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.

I’ve promoted the 2020 Mississippi Medallion winners Colorblaze coleus, beautyberry and Luscious lantana for the last three weeks. Now, I want to tell you about the fourth and final 2020 selection, Garden Gem tomato.

This will come as a surprise to the Southern Gardening Nation, but I think I’m starting to like eating fresh tomatoes. I’m certainly looking forward to picking fresh Garden Gem tomatoes this summer.

One of my favorite easy-care, flowering plants has to be lantana. This low-maintenance plant is highly tolerant of the hot, humid summers in our Mississippi gardens.

It’s no wonder that lantana has been selected as a Mississippi Medallion winner three times.

Through February, I’m highlighting plants named 2020 Mississippi Medallion winners. Each of these winners is superbly adapted to our garden and landscape environment.

This week, I want to tell you about American beautyberry, a winner that is a native species found across the Southeast. It is known botanically as Callicarpa americana.

A couple of weeks ago, I had the privilege of introducing the 2020 Mississippi Medallion Winners at the Gulf States Hort Expo in Mobile, Alabama. This is a special group of selections, as the Mississippi Medallion program is celebrating its 25th anniversary in 2020.

The plants selected for 2020 include Colorblaze coleus, beautyberry, Luscious Series lantana and Garden Gem tomato.

It may be chilly outside, but don’t let that deter you from going outside and working in your garden and landscape. Grab a jacket and your gardening tools, there is plenty to be done during February!
