BASIC CARE:
· Crapemyrtles love the heat, so put them in the sunniest spot you have. They will love the extra heat that occurs near a south-facing wall or fence. They are extremely drought-resistant once established.
· Fertilize in spring, because they bloom on ends of new growth. Preferably Plant-tone or comparable dry fertilizer. Liquid feeds of Miracle-gro are fast-acting but need to be repeated.
· Trim in early spring (April or early May), ideally before new growth ensues. Later trimming will not hurt the plant, but may delay or eliminate flowering. If you trim a branch, it needs at least 5-6 weeks of hot weather before it blooms. So, hedging a crapemyrtle in late June may ruin your chances to enjoy its blooms.
· Mulch generously in the fall. This protects the root zone from freezing completely and aids survival.
CRAPEMYRTLE NO-NOs:
· Do not fertilize after August 1st. The resulting new growth will not harden off properly before frost and will die back in winter.
· Do not prune heavily after August 1st. Again, the resulting new growth after pruning will not be ready for winter.
· Do not plant in an area that puddles after a rain. Plant in soil that drains very well, such as a sloping area or raised bed.

Keep in mind that Crapemyrtles are naturally late to come out in spring, but then grow rapidly with the onset of hot weather. So be patient, and Enjoy!
