Garden Checklist for March 2011

Russellia equisetifolia is a heat-loving perennial favored by hummingbirds
- Often, tomato and pepper plants started outdoors from seed will grow so quickly they will catch up with commercial plants in size within a few weeks. For many gardeners, this is the only way to obtain rare or heirloom varieties. But because this has been a winter with erratic weather patterns, it's best to keep an eye on young tomato transplants so that they may be covered if the threat of a late frost occurs.
- Don't be in a hurry to set out young pepper plants. Wait until the temperatures seem to be settled.
- Pruning of evergreens and summer flowering trees and shrubs should be completed in early March. Prune spring flowering trees and shrubs as soon as they finish blooming.
- Start hanging baskets of petunias, ferns and others for another dimension in landscape color. One attractive begonia plant can yield a number of others through careful rooting of stem cuttings.
- Plant dahlia tubers in fertile, well-drained soil.
- In North Texas there is still time to plant seeds of your favorite annuals in flats to be transplanted out-of-doors when danger of frost is past.
- Select and order caladium tubers as well as coleus plants for late April and early May planting. Do not plant caladiums until soil temperature reaches 70°F.
- As camellia and azalea plants finish blooming, fertilize them with three pounds of azalea-camellia fertilizer per 100 square feet of bed area. Check mulch on azalea and camellia beds and add where needed.
- Fertilize roses every 4 to 6 weeks from now until September.
- Beware of close-out sales on bare-root trees and shrubs. The chance of survival is rather low on bare-root plants this late in the season. Your best bet at this time of year is to depend on container-grown or balled-and-burlapped plants for landscape use.
