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.

Red, green, and yellow pods on a Chilly Chili plant, a colorful pod producer without the heat.

Late summer and early fall are among my favorite times of the year because the ornamental peppers are starting to really color up.

More and more fellow gardeners are jumping on the bandwagon and planting these beauties in their landscapes. These plants are hot -- in landscape character and accent -- and they carry the garden through the fall season and maybe beyond.

Most ornamental peppers begin setting fruit as the temperatures rise, so the best show is always saved for late summer and continues through the fall as they keep producing. This means you need to set these plants out in the late spring.

A Lycoris, pink/red flower with no foliage, better known as the spider lily or naked lady.

This is the time of year many gardeners have been waiting for all summer.

If you’re thinking about the cool front that blew through this past weekend, I’m afraid you’re incorrect. What I’m talking about is the emergence of naked ladies in gardens all across Mississippi.

I’m talking about the seemingly magical plants known botanically as Lycoris. Common names include magic, surprise or resurrection lily, but some gardeners simply call them nekkid ladies.

I’m often asked which flowering plants I think are best for our landscapes and gardens. This is not a simple question!
 
Through the Southern Gardening column and television program, I try to highlight great garden plants. Of course, these flowering plants happen to be my current favorites. That means my list of favorites is in a constant ebb and flow, as many readers know.
 
Today, I want to tell you about a landscape star that is shining brightly while others have faded pretty badly as we near the end of the meteorological summer. Today’s star is the penta. The reference to stars is very apt, as one common name for this plant is Egyptian Star Cluster.

This year has been a challenge in my home landscape and garden.

First, we have had a lot of rain: more than 93 inches and counting collected in our Community Collaborative Rain, Hail & Snow Network rain gauge. If you’re interested in being a volunteer rain reporter for them, go to http://www.cocoraahs.org for more information. I’ve seen so many waterlogged landscape beds and lawns that just won’t dry out.

The second big challenge was the heat. When it’s not raining, the high temperatures and humidity have maintained heat indexes that make me -- and many others gardeners -- just stay indoors. Surely that yard work can be put off until October.

But I’ve taken the steps to make my gardening an easier chore
