Perennial planting, care and maintenance

Set perennial plants in their permanent places so their roots are completely covered with prepared soil, but avoid burying the stem or crown. Place container-grown plants the same depth that they were grown; place dormant plants at the depth at which they grew the previous season. To encourage side root growth, make a planting hole twice as wide as deep. With bare-root perennials, spread the roots outward as well as downward. For container-grown plants, loosen encircled roots and shake some of the potting soil into the planting hole. Remember to crumble away the top edges of a peat pot to prevent water loss through wicking. Do not let roots dry out, especially during transplanting.

Water the plants thoroughly to force out any air pockets and to settle the soil. Mark and label the plantings. Mulch the bed surface with pine straw or bark to keep soil from drying, crusting, and overheating in the summer, and to prevent many weed seeds from germinating.

Care and Maintenance

If you do not mulch your plants, use shallow cultivation in the spring and early summer to break and aerate compacted soils. This also aids in water penetration and makes it easier to incorporate fertilizer. Summer cultivation can damage shallow roots and is more difficult because the plants will be larger. Early in the season, stake tall plants with wire stands or bamboo canes. Use care to avoid root damage.

Apply fertilizers sparingly to plants early in their growing season, after new growth begins to show. If plants are growing well, no additional fertilizer may be needed; otherwise, a second light feeding will be helpful several weeks into the season.

In the fall, cut the old plant stalks to the ground after the leaves have fallen and mulch to protect crowns and roots from the harsh extremes of our mild weather followed by sudden cold spells. Remove any winter annual weeds that may have germinated before applying mulch. Fall is also a good time to divide many plants that may be encroaching on one another.

Home gardeners in Mississippi need colorful plants that hold up to the hot conditions we have every year. One group of plants that is a great choice for summer color is salvia, which includes both perennial and annual top performers.

The annual Salvia Splendens, as the name suggests, can't be beat. It is commonly called scarlet salvia, but it comes in a variety of bright colors.

Christine Coker, a horticulture specialist with Mississippi State University, began sowing the seeds for her career in elementary school as a 4-H member. Now, she helps put food on Mississippians’ tables with her research and Extension projects.

BEAUMONT, Miss. -- For 16 years, Christine Coker has been doing what she loves: putting food on people's tables.

"In college, I really liked the study of plants, but I knew I wasn't going to be the world's greatest botanist," she said. "What I really wanted to do was feed people."

I really like to the flowering annual purslane in our hot summer landscapes. It's a vigorous, low-growing plant that forms a colorful carpet with succulent foliage.

But I plan to write about that wonderful plant in the future. Today, I want to extoll the virtues of one of its cousins: moss rose.

Moss rose has fleshy, succulent foliage that helps it hold up to the summer heat. The 1-inch-long, cylindrical foliage is bright green and arranged in clusters on the stems.

VICKSBURG, Miss. -- The Southern Gardener, Gary Bachman, would like to see Mississippi's historic bed and breakfast owners step up their game in the garden.

"What is your budget for your landscape and labor costs? Do you serve anything you grow and use your own flowers?" Bachman asked owners at a recent Mississippi State University Extension Service workshop. "I want to show you how, with minimal effort and minimal out-of-pocket expense, you can get a good return on investment from the landscape of your historic properties."

With summer officially here and hot and humid weather firmly in place, many gardeners -- myself included -- like to look at a pretty landscape, but don't really want to get out and do much work in that same landscape.

So selecting plants that look good without much work pique my interest. One plant that doesn't disappoint me is Sun coleus.
