March is a good time to shop for and add lungwort (Pulmonaria) and Lenten rose (Helleborus) to your garden. Lungwort is an early flowering shade perennial that often struggles in the heat and humidity of our Tennessee climate, so be aware that Pulmonaria longifolia cultivars and hybrids are much more durable. Good selections are 'Roy Davidson,' 'E.B. Anderson,' 'Trevi Fountain' and for its vigor and heat tolerance, 'Diana Claire.'

Climbing roses should not be pruned until after their first flush of growth. Now is a good time to tie the canes to a support before they flush out with spring growth.

Prune spring-flowering shrubs (azaleas, flowering quince, Forsythia and Loropetalum) soon after they finish flowering, but only if they need it. Selectively cut old or unruly branches by reaching deeply into the shrub leaving no visible stub. making the cut just above a joint. This pruning method will keep them from looking like meatballs.

A good option for Loropetalums that have outgrown their space is to tree-form them. They can easily be limbed up by removing lower branches.

Kerria japonica, also known as Japanese kerria or yellow rose of Texas, often has dead branches. Follow them to the base to cut them. Remove older branches the same way to keep the plant looking good. Older, overgrown or neglected plants can be cut to the ground for rejuvenation.

Azaleas often show symptoms of lace bug and spider mite infestations during the hot months of summer. This damage can be prevented by a onetime early application of the systemic insecticide imidacloprid. This insecticide should be poured in liquid form around the root system as the flowers fade, spreading the active ingredients throughout the plant issue where it remains effective through the growing season. Bayer Advanced Tree and Shrub Insect Control is a common brand that contains this safe and effective insecticide. Always follow label directions when applying any pesticide.

Spring is a good time to freshen up the mulch in your landscape. Remember not to pile it around the trunks of your trees and shrubs. If using a pre-emergent herbicide, be sure to apply it before spreading your mulch to prevent the sunlight from breaking it down. It also forms a more effective barrier when allowed to bond with soil particles.

Remember it is not necessary to fertilize well-established trees or shrubs. If you are trying to encourage faster growth on new plantings, a balanced granular fertilizer scattered on the soil surface is effective. Be careful not to overdo it. Tree spikes or drilling fertilizer into the root zone is unnecessary and expensive.

Cut back any woody perennials that may need it, like rosemary, rue, lavender, Santolina and Artemisia. If done before the danger of frost has passed, new growth may appear, and a freeze can kill that new growth and sometimes the entire plant.

Plant butterfly weed (Asclepias), parsley, dill, rue and pipevine to encourage butterflies in your garden. The foliage of these plants provides food for the caterpillars. Aristolochia fimbriata is a lovely ground-cover-type of pipevine that is covered each year by the pipevine swallowtail caterpillar at the UT Gardens, Jackson. It may be al little hard to find for sale, but worth seeking out.

Caladiums and vinca need warm soil. Caladium tubers will rot in cool soil, and vinca will be disease-prone, or exhibit stunted growth. Night temperatures should regularly be above 60 degrees F before planting.
