Deep Watering vs. Frequent Watering: Which Is Better?

  

Walk through any neighborhood during a hot summer, and you'll see sprinklers hissing away every morning. Many gardeners assume that watering a little every day is the safest way to keep plants alive. It's an understandable instinct. When the weather is hot, everything looks thirsty.

But appearances can be deceiving.

In most cases, deep watering is far healthier than frequent, shallow watering. Understanding the difference can mean the difference between a garden that merely survives summer and one that thrives despite it.

What Is Deep Watering?

Deep watering means applying enough water that moisture penetrates well below the soil surface, encouraging roots to grow downward. Instead of wetting only the top inch or two of soil, the goal is to soak the root zone several inches deep.

Depending on the plant, this may mean watering for 20 to 60 minutes with a soaker hose or drip irrigation, or applying water slowly by hand until the soil is thoroughly moistened.

Afterward, allow the upper layer of soil to begin drying before watering again.

What Is Frequent Watering?

Frequent watering usually means applying small amounts of water every day or every other day. While the soil surface stays damp, the moisture rarely reaches the deeper roots.

This approach often encourages roots to remain near the surface, exactly where the soil heats up and dries out the fastest.

The result is a plant that becomes increasingly dependent on constant watering.

Why Deep Watering Wins

Stronger Root Systems

Roots naturally grow toward moisture.

When water penetrates deeply into the soil, roots follow it downward. Plants develop larger, stronger root systems that can draw moisture from a much larger volume of soil.

During a dry spell, these deeper roots continue finding water long after shallow-rooted plants begin to wilt.

Better Drought Tolerance

A deeply watered plant is far more resilient.

Even if you miss a watering during vacation or an unexpected busy week, established plants with deep roots often continue growing with little stress.

Plants trained on daily shallow watering may wilt dramatically within a single hot afternoon.

Less Disease

Constantly damp soil near the surface encourages fungal diseases, algae, fungus gnats in containers, and sometimes root rot in poorly drained soils.

Allowing the soil surface to dry between waterings reduces many of these problems.

More Efficient Water Use

Deep watering often uses less water overall.

Although each watering session is longer, you water much less frequently. Less water is lost through surface evaporation, and more reaches the roots where it's actually needed.

When Frequent Watering Makes Sense

Like most gardening advice, there are exceptions.

Newly Planted Annuals

Freshly planted flowers and vegetables haven't developed extensive roots yet. During their first week or two, they may require more frequent watering while becoming established.

As roots begin growing outward, gradually transition to deeper, less frequent watering.

Seedlings

Seeds and tiny seedlings need consistently moist soil near the surface to germinate successfully.

Allowing the surface to dry completely can stop germination or kill delicate young roots.

Once seedlings develop several true leaves, begin spacing waterings farther apart.

Containers

Container plants dry much faster than garden beds because they hold relatively little soil.

During extreme summer heat, pots may require daily watering—or even twice daily for small containers or hanging baskets.

Even then, water thoroughly until excess drains from the bottom rather than giving only a light sprinkle.

Sandy Soils

Very sandy soils drain rapidly.

Even with deep watering, they may need irrigation more often than heavier clay or loamy soils because they simply cannot hold as much moisture.

Signs You're Watering Too Often

Your plants may actually be receiving too much attention if you notice:

• Yellowing leaves despite moist soil
• Wilting even though the ground is wet
• Mushy stems
• Moss or algae growing on the soil
• Fungus gnats around houseplants
• Roots staying near the surface
• Constant weed germination

These symptoms often indicate overly wet soil rather than drought.

How to Water Deeply

A few simple practices make deep watering much more effective:

• Water early in the morning when evaporation is lowest.
• Apply water slowly so it soaks in instead of running off.
• Use drip irrigation or soaker hoses whenever possible.
• Check soil moisture by digging 4 to 6 inches down rather than judging by the surface.
• Mulch with 2 to 3 inches of organic material to slow evaporation.
• Water only when plants actually need it, not simply because it's Tuesday.

Don't Judge by the Surface

One of the biggest mistakes gardeners make is watering because the top inch of soil looks dry.

In reality, the soil several inches below may still contain plenty of moisture.

A simple trowel or soil probe can reveal whether water is truly needed. Dig a small hole and feel the soil with your fingers. If it's cool and slightly moist several inches down, your plants are probably doing just fine.

Different Plants, Different Needs

Not every plant follows exactly the same schedule.

Shallow-rooted vegetables like lettuce need more frequent moisture than deeply rooted tomatoes. Hydrangeas typically require more water than established rosemary or lavender. Native plants adapted to your local climate often need surprisingly little supplemental watering once established.

Learning each plant's natural preferences will save water and produce healthier growth.

The Bottom Line

If you remember only one principle, let it be this:

Water deeply, then wait.

Deep watering encourages roots to explore the soil, producing sturdier plants that withstand heat, drought, and everyday stresses far better than plants pampered with frequent shallow watering.

Like raising a child, the goal isn't constant dependence but growing strength. A garden with deep roots is a garden prepared not just for today's sunshine, but for tomorrow's heat as well.

Five Mistakes Gardeners Make During Heat Waves

 

Summer heat can test even the most experienced gardener. A string of days above 90°F, paired with warm nights and drying winds, places enormous stress on plants. Yet many losses during a heat wave aren't caused by the weather alone. They result from well-intentioned mistakes made by gardeners trying to help.

Understanding how plants respond to extreme heat can help you avoid unnecessary damage and keep your garden healthy until cooler weather returns.

1. Watering Too Often, But Too Shallow

One of the most common mistakes is giving plants a quick sprinkle every day. While this wets the surface, it rarely reaches the deeper roots where plants actually need moisture.

Shallow watering encourages shallow root systems, making plants even more vulnerable when temperatures soar.

Instead:

• Water deeply one or two times each week, depending on your soil and rainfall.
• Water early in the morning whenever possible.
• Allow the moisture to soak six to eight inches into the soil.
• Check the soil before watering again rather than following a strict schedule.

Container plants are an exception. Pots dry much faster than garden beds and often require daily watering during prolonged heat.

2. Fertilizing Stressed Plants

When plants begin to wilt or stop growing, it's tempting to assume they need fertilizer. In reality, heat stress often causes plants to slow their growth intentionally.

Applying fertilizer during extreme heat can create additional stress by encouraging tender new growth that cannot withstand the weather. Excess fertilizer may also increase salt concentrations around the roots, making it harder for plants to absorb water.

Wait until temperatures moderate and plants begin growing normally again before feeding them.

3. Pruning During Extreme Heat

Heavy pruning removes valuable foliage that shades stems, fruit, and developing branches.

Leaves are the plant's natural sunscreen. During a heat wave they protect bark from sunscald and reduce water loss.

Avoid:

• Heavy pruning of shrubs
• Removing large limbs from trees
• Cutting back perennials severely
• Deadheading excessively if plants are already struggling

Instead, postpone major pruning until cooler weather returns. If something must be removed because it is dead or diseased, make only the necessary cuts.

4. Leaving Bare Soil Exposed

Bare soil acts like a skillet in July. Direct sunlight can drive soil temperatures well above the surrounding air temperature, damaging fine roots and causing moisture to evaporate rapidly.

A layer of mulch helps protect the root zone.

Good choices include:

• Pine straw
• Shredded bark
• Wood chips
• Leaf mold
• Compost

Maintain two to four inches of mulch around most landscape plants, keeping it a few inches away from trunks and stems to prevent rot.

Besides conserving moisture, mulch helps moderate soil temperatures and reduces weed competition.

5. Ignoring Signs of Heat Stress

Many gardeners panic when leaves wilt during the afternoon and immediately reach for the hose.

But temporary afternoon wilting isn't always a sign that plants need water.

Many plants recover naturally as evening temperatures fall.

Before watering:

• Check the soil several inches below the surface.
• Look for recovery in the evening.
• Watch for repeated morning wilting, which is a stronger indication that watering is needed.

Persistent wilting, scorched leaf edges, flower drop, and premature fruit drop are signs that the plant is struggling beyond normal heat response.

Bonus Tip: Know Which Plants Need Extra Attention

Some plants handle heat surprisingly well once established.

These include:

• Lavender
• Rosemary
• Coneflower (Echinacea)
• Black-eyed Susan (Rudbeckia)
• Sedum
• Lantana
• Yarrow (Achillea)

Others need closer monitoring during prolonged heat, especially if newly planted:

• Hydrangeas
• Hostas
• Lettuce
• Spinach
• Impatiens
• Newly planted shrubs and trees

Young plants with undeveloped root systems are almost always the first to suffer.

Let the Garden Rest

Perhaps the greatest mistake is believing something must always be done.

During a heat wave, nature often benefits from restraint. Resist the urge to fertilize, prune, or constantly disturb the soil. Keep plants watered appropriately, maintain a protective layer of mulch, and allow them to conserve their energy.

Most established plants have survived countless hot summers before. Given proper care and a little patience, they'll usually recover when cooler temperatures and autumn rains finally arrive.

A gardener's wisdom is often measured not only by what he does, but by knowing when to leave well enough alone.

Haws Watering Cans: A Tradition of Craftsmanship in the Garden

 

In the quiet world of gardening tools—where usefulness usually outruns beauty—there stands one company whose humble product has become something of a legend. That company is Haws, the English maker of watering cans that gardeners around the world recognize instantly by their graceful long spouts and finely perforated roses. For nearly a century and a half, these watering cans have embodied a simple but noble idea: if you care about plants, the tools you use ought to be worthy of the work.

A Victorian Invention That Changed Watering

The story begins in 1886, in London, when a man named John Haws patented a new design for a watering can. The old models of the day were awkward—hard to carry, difficult to tip, and prone to pouring water in a heavy stream that battered young plants. Haws set out to fix that.

Ironically, John Haws was not known as a particularly successful gardener. While serving in the British colonial service in Mauritius in the 1880s, he struggled to grow vanilla and began tinkering with watering can designs that might improve his odds. Out of that practical frustration came a remarkably elegant solution.

His patented watering pot featured a balanced shape, a long spout, and a removable “rose” head that dispersed water into a gentle shower. As Haws described it in the patent:

“Much easier to carry and tip… more adapted for use than any other.”

Gardeners quickly agreed. The design proved so effective that the essential form of the Haws watering can has changed very little in the decades since.

Building a Reputation for Quality

After John Haws died in 1913, the company passed into the hands of his nephew Arthur Haws, who moved the factory to Bishops Stortford and continued refining the product. At its peak, dozens of craftsmen worked there producing cans that were admired not only for their function but also for their elegance.

Arthur was famously obsessive about the watering rose—the perforated head that breaks water into droplets. In the early factory, one worker’s entire job was to punch every tiny hole by hand, ensuring that the spray fell evenly and gently over seedlings and delicate foliage.

That sort of attention to detail is the reason Haws cans developed a reputation as the “Rolls-Royce of watering cans.”

The company survived wars, economic recessions, and ownership changes, but the essential idea remained intact: make the finest watering can possible and gardeners will recognize its worth.

Craftsmanship That Still Matters

Even today, Haws watering cans are largely hand-made in England, using quality metals such as galvanized steel or copper, often with brass fittings and carefully engineered components.

Their design is not merely decorative—it is practical in ways that seasoned gardeners immediately appreciate:

• Balanced weight distribution makes a full can easier to carry and pour.

• Long, narrow spouts allow precise watering between plants.

• Interchangeable roses produce a soft rainlike spray that won’t disturb soil or seedlings.

• Durable materials mean the can may last decades with proper care.

The result is a watering tool that feels almost alive in the hand—responsive, predictable, and satisfying to use.

Why Serious Gardeners Love Them

A good watering can does more than hold water. It shapes how water meets the soil.

Haws cans excel at precision watering, delivering moisture gently and evenly so that seeds and delicate plants are not washed away. Their carefully engineered rose heads produce droplets similar to a light rain, an approach that protects fragile foliage and improves absorption into the soil.

Professional gardeners, horticulturalists, and even television personalities like Monty Don have praised the brand for this reason.

In a practical sense, the Haws design helps prevent common watering mistakes—overwatering, soil disturbance, and splashing that spreads plant disease.

A Tool That Becomes an Heirloom

There is also something less tangible at work here: pride of ownership.

Many modern garden tools are disposable—thin plastic, poorly balanced, made for a season or two. A Haws watering can feels different from the moment you pick it up. The metal is heavier. The spout is elegant. The rose unscrews with a satisfying precision.

Gardeners often speak of these cans the way woodworkers talk about a well-balanced plane or chefs about a forged knife. It is not merely a tool; it becomes part of the ritual of tending plants.

And because they are so durable, Haws watering cans are often passed down from one gardener to the next. Nearly 140 years after the first patent, many of the company’s cans are still built on the same principles—and in some cases, the same patterns—as the originals.

A Small Object With a Long Legacy

It is easy to overlook something as ordinary as a watering can. Yet the Haws story reminds us that even the simplest tools can embody craftsmanship, ingenuity, and tradition.

For gardeners, watering is not merely a chore. It is a quiet moment in the day—the gentle sound of droplets on leaves, the smell of damp soil, the feeling that something living depends on your care.

A Haws watering can does not make you a better gardener overnight. But it does something subtler: it invites you to slow down, to water thoughtfully, and to take pride in the small acts that make a garden flourish.

And in the end, that is exactly what the best tools have always done.

Should You Fertilize Your Garden in the Summer?

 

As the summer sun climbs high and gardens brim with life, many gardeners wonder: Should I fertilize during the heat of summer, or will I do more harm than good? The answer, like much in gardening, lies in understanding your plants, your soil, and the climate you’re working with.

Summer fertilization can be beneficial, especially for heavy feeders like tomatoes, squash, and container-grown plants that rapidly deplete soil nutrients. However, fertilizing in the peak of summer heat must be done with care. Heat-stressed plants, already struggling to retain moisture and function properly, may react poorly to a sudden influx of nitrogen—resulting in scorched leaves or accelerated dehydration. Slow-release organic fertilizers, compost teas, and diluted liquid feeds are gentler options that can give your plants the boost they need without overwhelming them. Always water deeply before and after applying any fertilizer to help nutrients reach the root zone and reduce the risk of root burn.

Ultimately, the best approach is to test your soil, observe your plants, and consider the temperature. If leaves are green and growth is steady, hold off. If your plants look pale or sluggish despite adequate watering, a mid-season feed might be just the ticket. Like a good Southern supper, timing and moderation make all the difference.

5 tips to help your garden make it through a heatwave

 

Is the current heatwave stressing you out? Think what it’s doing to your plants. Many plants – especially vegetables – need full sun. But during some summers it gets a little ridiculous. If your garden looks like it’s struggling during extreme heat, here are some tips to help you help your garden make it through.

• Water early and water deeply. Mid-day watering might seem like the best time to resuscitate your wilting garden, but it’s not. The hot sun will dry some of the water before it has a chance to percolate into the soil, and the wind might just blow the spray elsewhere. Water in the morning before the day heats up and the wind begins to stir. Water deeply, too. A light sprinkle won’t have a chance to soak much into the soil. Furthermore, roots will tend to stay near the soil surface where the water can be found. Deep watering will encourage deeper root growth.
  
• Add mulch. We can’t say this enough. A couple inches of mulch will help the soil to retain moisture, and mulch helps to suppress weeds, too. Grass clippings, straw, wood chips and chopped leaves are excellent mulch materials. In addition, the rotting organic material will build your soil into a healthier ecosystem.
• Provide some shade. Though many plants need full sun to flourish, a little shade during hot afternoons will protect them when they need it most. Shade cloth is a most popular solution.
• Lay off fertilizing for awhile. Fertilizer – especially nitrogen – encourages plant growth. Active growth stimulation during hot weather is just what your plants don’t need. Let them rest during hot spells, just as you would do yourself.
• Get rid of weeds. Weeds compete with your flowers and vegetables for moisture. Eliminate them. Your garden plants will thank you.

Call Before You Dig!

 

Call before you...WHAT?

‘Tis a season for planting. Homeowners are gearing up for improving their properties, making plans, buying trees and shrubs, and maybe even installing irrigation, fences or mailboxes. No doubt, this will involve digging holes or trenches.

Before you begin, you'd better find out what you're getting into. There could be electric power lines, outdoor lighting, conduits, gas lines, fuel oil pipes, buried telephone or internet cables, fiber optics, potable water or irrigation pipes/valves, sewage/drain pipes. You don’t want to cut through any of those. Accidents, some with very serious consequences, can occur if safety isn’t heeded, including explosions, flooding, electrocutions. Make a list of all utilities and contractors that you THINK might be involved.

Mark the specific area(s) where you’ll be working, so utilities aren’t flagging or painting your entire yard.

To find out utility locations, Dial 811 - Call Before You Dig, to make “a locate request.” It shouldn’t cost you anything, but it might. (Get that settled up-front.) The call center will contact all utilities in your area that subscribe to this service. You should receive a confirmation “ticket” or some such communication telling you which services have been contacted. Bear in mind, though, that not all utilities or contractors subscribe to this service! If you suspect that a utility wasn’t included on the list, double-check. Personally call the contractor, if necessary.

Here are a few of the most neglectful or uninformed contractors:

• Cable TV companies;
• Invisible dog fence installers;
• Irrigation contractors;
• Security firms.

In some cases they have no idea where their lines were buried. “It was so long ago…”

Utilities and contractors that have been notified must come to your property to mark their lines, usually with flags or paint, within a specified period of time particular to your state or area.

The markings are color-coded.

Red: Electric power lines, cables or conduit, and lighting cables.
Yellow: Gas, oil, steam, petroleum, or gaseous materials.
Orange: Communication, alarm or signal lines, cables or conduits, and fiber.
Blue: Potable water.
Purple: Slurry, irrigation and reclaimed water.
Green: Sewers, drainage facilities or other drain lines.

Once you’ve waited the few days required, check your list to confirm that the notified utilities have responded. If some didn’t, report it.

When you’ve done everything required for your safety, proceed with caution. Be sure not to dig where markings have been displayed. Dig promptly before the markings disappear due to wind, rain or landscape maintenance. Avoid surprises.

Do you really need a raised bed garden? No, but…

 

Back in the day, most gardeners gardened in the good old-fashioned way by planting directly in the ground. It seemed like the right thing to do because we’d always done it that way, and others had, too. There’s certainly nothing wrong with that if it’s your choice.

But some of us have abandoned our past methods and adopted raised-bed gardening for our vegetable and ornamental plants. Why? Here’s why.

 

Weed control is less of a problem. Because we raised-bed gardeners usually buy soil and humus or produce our own compost, fewer weeds are imported than if native soil is used. This saves time, energy and frustration.

Watering is easier to control. Plants are usually grown closer together. There’s no wasted space. Consequently, irrigation is accurately directed where it’s needed. Less water is wasted irrigating spaces between rows normally found in traditional gardens. Whether or not you have a private well, this represents a significant savings.

Soil compaction is eliminated because you aren’t tromping through your raised beds.

Raised beds invite closer plant spacing, therefore producing higher yields in less space.

Soil in containers and raised-beds warms earlier in the season due to sun exposure on the sides, stays warm longer, and extends the growing seasons. When cold weather does arrive, it’s easier to protect plants with protective frost covering.

Because soil is confined in the containers, rainfall and irrigation waters don’t run off. Erosion is reduced.

You can adjust your garden soil to suit the needs of your crops in their assigned spaces. It’s easier to amend pH and nutrient levels as required, and native soil has less of an impact on your planting soil.

No more bone-jarring roto-tilling is required!

You can garden wherever you want. Would-be gardeners with limited space on a balcony or patio can still grow stuff and transform their environment into productive spaces.

Raised-bed gardeners don’t have to bend over so far to work. What’s more, gardening height can be adjusted to suit their needs. This is just the ticket for disabled persons and senior citizens

So, if you desire to plant a garden but feel that you don’t have the space or ability to do it, raised-bed gardening might be just right for you.

This Homeowner Has Uneven Soil Moisture Issues

Q. One section of our lawn gets dry sooner than others. We run the sprinkler system the same length of time in each section. The sprinklers in the dry area also water another area that doesn't dry out, so we can't really run them longer without getting the other area too wet. Help!

A. You should figure out why the area in question dries so soon. The reason might include any of the following:

• The grade of the lawn is higher in the dry area than in the others, so the water is draining away;
• The soil type is sandier in the dry area than in the others, so the water perks down sooner;
• The sprinkler heads in the dry area are not covering it properly;
• The sprinkler heads in the dry area are not delivering enough water;
• The sprinkler heads are spaced too far apart.

The simplest thing will be for you to place several empty cans of the same size around your lawn, especially within that irrigation zone. Run the irrigation for the normal period of time, then measure the water in the cans. This will indicate whether enough water is being distributed, and whether it is being distributed evenly. If the dry area is receiving less water, try replacing the existing nozzles with larger ones. If your water pressure is insufficient to support larger nozzles, replace the nozzles in adjacent normal areas with smaller ones, and run that zone a little longer.

Changing nozzles is not difficult, but it may require some inexpensive, specialized tools. If you can't do it yourself, or you simply don't want to be bothered, find a competent lawn irrigation specialist.

If the problem is due to grade or soil type, know that the grade can be changed or the soil can be amended. If the sprinkler heads are spaced too far apart, you may need to have additional heads installed. A well-respected landscape specialist should be able to help you.

FAQ: The leaves on my 5-year old maple tree are turning brown around the edges. What's causing it?

Q. The leaves on my 5-year old maple tree are turning brown around the edges. What's causing it? Is there anything I can do? Do you think it will live?

A. I expect that your tree is suffering from drought and heat. There's been a lot of that going around this year. Maples are not particularly drought tolerant, especially young ones. You need to water it, and you need to do it right. One option is to rig up a drip irrigation system around the base of the tree. Ask for instructions at your local garden center or check the internet. Most drip irrigation manufacturers provide instruction pamphlets.

The irrigation line should be placed on the ground around the tree just inside the drip line. That's where the feeder roots are. The drip line is under the outer branches. Watering close to the trunk won't help. There are no feeder roots there. Irrigate long enough for the water to soak deeply into the ground. Three or four hours the first day is not too long. The soil should be kept moist, not soggy.

Another option is to place the end of your garden hose on the ground just inside the drip line and let it drip slowly for one or two hours. Then move it to another place around the tree and let it drip some more.  Keep doing it until you've watered entirely. Again, the soil should be kept moist, not soggy.

A third option is to install a drip irrigation bag on your tree. There are several brands. Treegator is the original. These are placed around the trunk of the young tree and filled with water. The water is gravity fed slowly into the root ball. If the tree is too large and the drip line too far from the trunk, drip irrigation bags won't do the job.

Will it survive? I don't know. That depends on how much the tree has suffered. It might survive through this season but croak the next, or even the next. In addition, drought stress can weaken trees to the point that they succumb to other afflictions.

As I've often heard said, "an ounce of prevention is worth a pound of cure." Watering a little during dry spells when the tree is healthy is better than watering a lot when it's suffering. But we usually don't think of it until symptoms begin to appear. That's the way we are about a lot of things, isn't it?
