- Check with your local county agent for the average last killing freeze date for your area. Killing freezes can and do occur after this date but it is a good indication.

- 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.
- 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 geranium and coleus plants for late April and early May planting. Do not plant caladiums until soil temperature reaches 70F.
- 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.
