How to replace turf with asiatic jasmine.

Q: We want to cover zoysia turf with asiatic jasmine....[but] wonder if we must remove the turf, or can we plant the jasmine over very closely cropped zoysia? Also, how do we plant "bare root" jasmine? Thanks for answering all the rookie questions.

A: Yours are good questions. Thanks for asking.

I understand that you want to replace the turf with asiatic jasmine, but don't know whether to remove the zoysia or plant into it. Though I often recommend tilling, removing the turf and/or tilling the soil will expose weed seeds that have been long-dormant, resulting in a weed problem. On the other hand, the living turf will present competition for moisture and nutrients the jasmine will need. Why not crop the turf, spray it with herbicide and leave the dead grass in place? The zoysia should expire in about 10 to 14 days. This will leave a mulch cover over undisturbed soil. Unless the soil in the planting site is compacted,  the jasmine should grow well. If the soil is a little compacted, you could loosen it around each planting hole with a trowel before installing the jasmine. Incorporate a bit of fertilizer or compost in each hole before planting, taking care that synthetic fertilizer doesn't contact the new plants.

Planting bare root is easy enough, though takes a little care. Be sure that the roots are kept moist before planting. Do not allow them to dry out. Follow the instructions about loosening the soil and adding fertilizer or compost as noted above. Make sure that the roots are spread out a bit and covered with sufficient soil. Water well. Maintain soil moisture until the plants are established, allowing the soil to drain before irrigating again. Don't drown them with love. Depending on your site, considering sun, wind, etc.,  you might be watering every couple of days. Monitor the condition of the plants and soil throughout the season. Once asiatic jasmine is established, though, it is tolerant of dry conditions.

You could add some mulch on the dead zoysia between the jasmine, if you like, for extra moisture retention and weed suppression. Since you live in the South, pine straw might be readily available to you. Don't blanket the jasmine plants themselves.

I hope this helps. If you have any questions, don't hesitate to contact me.

How To Make A Simple Composting Barrel

 

Composting happens all the time without human intervention. Leaves fall, grasses die, wood rots and the circle of life from a seedling to a plant’s final end returns the basic building blocks of life to the soil for another go-round.

Gardeners can use this process to their benefit by gathering and confining the organic material to an easily accessible location for the process to occur. It can be in an open pile or contained in a box, barrel, bucket or bin. The choice is yours. The end result is COMPOST – black gold for the garden.

For the organic material to be useful, it must be decomposed. For it to be useful sooner, it must decompose faster. The key to faster decomposition is turning – turning the material over and over so that all the ingredients are exposed to the insects, worms and micro-organisms for digestion and decay.

We’ve tried every basic method – open piles, boxes and bins. Some were flimsy. Others were not very durable. Some were simply inconvenient to manage. I’ve seen the manufactured barrels that rotate on metal or wooden stands, or those on rollers for kicking over and over. I was sold on the concept, but not the products on the market, so I decided to try composting in a barrel of my own making.

I paid a visit to The Barrel Man. He’s just down the road from me. He sells all kinds of used barrels at very reasonable prices. I selected this 60-gallon plastic, flat-sided barrel with a screw-on lid. It also has an inner lid for better sealing.

“What was it used for?”, I asked.

“Meat processing by-products”, he said.

I opened it up to sniff. It smelled clean enough; not offal.

“Oh, it’s been cleaned”, he informed. “It’s food-grade plastic.”

So, I paid him, loaded it into my pickup truck and headed home.

Why did I choose a flat-sided barrel? I’m glad you asked. I don’t intend to mount it on a stand, but to push it over on its side and kick it around several times to mix the ingredients, and maybe turn it upside-down, too. I figure the flat sides will do a better job of shifting and mixing the material inside for faster decomposition. It can’t get any simpler than that.

The only tools needed were a power drill, a 1” hole saw, a 2” hole saw, and a big, black, felt-tip marker.

I began by marking the ribs on all four sides where I’d drill the aeration holes. These holes were drilled with the 1” inch hole saw.

Then I turned the barrel upside-down. I used the 2” hole saw to penetrate the very center, and the 1” hole saw to make four more drainage holes around the circumference. When the barrel is filled, I hope these drainage holes will also provide entry ways for earthworms and other busy critters when the barrel is in direct contact with the ground.

Important tips: 1) the bottom is thicker than the sides, so takes longer to penetrate; 2) take your time cutting with a firm hand, 3) better do your work over a tarp so you can gather the plastic shavings and dispose of them properly.

It wasn’t long before I had the barrel mostly filled with leaves, vegetable and fruit scraps, coffee grounds and torn paper filters, shredded documents in layer upon layer. I could see that it wouldn’t be long before my barrel would be maxed-out. So I headed back to The Barrel Man for more barrels. These flat-sided composters can be easily lined up near the garden, all in different stages of decomposition, taking less space than round barrels.

 That’s all there was to it. You can do it, too.

Soil Tests – The Why and How

 

No doubt you've learned somewhere that soil tests provide essential guidelines for gardening. Perhaps the "why" and "how" have eluded you. This article might help.

You’ve probably noticed that different types of plants grow in different places. That’s because they are either native or adapted to distinct habitats. Drive through the countryside and you’ll see what I mean. On one side of a hill you might find a hardwood forest. The other side might be predominantly native pine. In another place there will be a grassy meadow. Farther along you might see a bog with sedges and alders. Each area has its own soil type, nutrient levels, drainage and chemistry. The lesson here is that plants thrive in locations and conditions that meet their needs.

Garden spaces are sometimes not so easy to judge. Further inspection and discovery will probably be necessary. Follow a similar exercise to your drive in the country when garden planning. Walk around your landscape taking note of drainage, sun exposure, slope and the plants that are thriving. Even moss and weeds can tell a story, but we'll delve into that some other time.

There are a couple of ways to determine your soil type, chemistry and condition. The first is to take a soil sample for testing. The second is to utilize the USDA Web Soil Survey tool. Taking a soil sample is easy enough. Using the USDA Web Soil Survey tool? Not so much.

A basic soil test will tell you three things: the soil pH (acidity or alkalinity), phosphorus (P), and potassium (K). Nitrogen (N) is not so easy to determine, so test results probably won’t show it. Advanced soil tests can reveal organic content and some minor element content. Keep in mind that a single soil test only provides a “snapshot” in time. Some of the element levels can change over the seasons.

Obtain a soil sample bag or bags from your local Cooperative Extension Service office. Fill in the blanks with your name, address and contact information. Check off the tests you want performed. Collect soil samples from various comparable places around your garden or landscape to provide a soil “profile.” Before taking samples, remove leaves and other debris from the immediate site. Scrape down to the actual soil. Mix the samples thoroughly in a clean plastic bucket. Transfer the mix to the soil sample bag, and return it to the office. A report should be mailed to you.

Using the USDA Web Soil Survey tool is another matter. You might find it here:

https://websoilsurvey.nrcs.usda.gov/app/

I can’t walk you through the steps. It wasn’t intuitive for me. You’ll just have to play around with the website until you figure it out for yourself. Nearly every square foot of the United States is included in the survey. No doubt you’ll find your square feet.

Here’s an example. Zeroing in to a delineated area on my property shows that it consists of two soil types: Pelham loamy sand (5.4% of the area) and Tifton loamy sand (94.6% of the area). What does that mean? According to the USDA, “The Pelham series consists of very deep, poorly drained, moderately permeable soils that formed in unconsolidated Coastal Plain sediments. These soils are on nearly level broad flats, toe slopes, depressions and drainageways.” “The Tifton series consists of very deep, well drained soils that formed in loamy marine sediments. Tifton soils are on interfluves. Slopes range from 0 to 8 percent.” Understanding these characteristics helps me figure out what to plant and where, especially if drainage is important.

With such facts in mind, the gardener can choose suitable crops and where to plant them. Obviously, this isn’t so vital if one is planting in containers or raised beds. However, when the homeowner is planning landscape plantings of trees, shrubs, perennials and vines, they are essential considerations.

You might have some particular plants in mind. If so, read the plant descriptions and learn about their soil requirements. Choose those that seem most compatible with your conditions.

If soil test reports indicate that amendments are necessary, make them weeks or months ahead of planting time to allow them to be incorporated into the soil and take effect.

It’s far easier to select plants appropriate to your situation than it is to dramatically change or amend your native soil to accommodate unsuitable plants of your choosing. Be realistic. Make it easy on yourself. Work with nature, not against it.

How To Plant Perennials From 2-1/2” or 3-1/2” Pots

 

It's not uncommon for folks to visit their garden shops at the first breath of spring, buy a few plants, then wander about the yard looking for some place to put them. That's not the way to go about it.

Before you purchase your plants choose them with your site conditions in mind. Site conditions include your USDA climate zone, sun exposure, soil moisture, soil texture, soil chemistry (soil pH) and those constraints that limit the types of plants you can grow.

Ideally, you should’ve begun preparing the planting bed before your plants arrived. If you haven’t begun preparations yet, set your plants aside out of the sun, wind, extreme heat or cold. Get started.

Have a soil sample tested. Drop by your nearest Cooperative Extension Office for some soil sample bags. Follow instructions on the bag. Your report should arrive in a few days. Follow instructions in the report. Plant your perennials with other plants having similar cultural requirements.

Prepare the planting bed by cultivating at least 8" deep, removing all traces of weeds. Compacted soil should be cultivated to 12" deep.  Amend the soil according to the Cooperative Extension Service report.

As a general rule, though, compost may be incorporated into the soil.  Incorporate 5-10-15 fertilizer at a rate of no more 2 lbs. per 100 square feet into the top 4" to.  6" of soil. Avoid synthetic fertilizers contacting any part of your plants.

Space plants in 3-1/2” pots about 12" to 18" apart. Space plants in 2-1/2” pots about 8” to 12” apart. Plant spacing is not an exact science. Sure, you must consider the mature sizes and growth rates of your plants, but spacing is as much a matter of your budget and patience.

Dig planting holes into the cultivated soil a little less deep than the depth of the growing container. Place the plants into the holes and back-fill, watering as you go. Press soil around the root balls. Do not cover entirely the root balls with soil. The tops should be slightly exposed. Add a top-dressing of mulch around the plants, not on top of them, about 1" deep.

Fertilize sparingly and allow soil to dry slightly between watering.  Few plants like to be waterlogged, though there are exceptions – particularly those that thrive in bogs and along water features.

Having done that, periodically remove weeds from the planting bed. Fertilize your plants as required.

What’s next? Enjoy the results of your labor!
