Depending on the weather, yearling Purple Martins should begin to start arriving now through the rest of the month, looking for nesting sites to colonize. Houses should be cleaned and ready to go up. No matter what, keep the housing up through June, martins may arrive and begin nesting as late as the end of June.
Taking Care of Trees and Shrubs
Feed deciduous trees and shrubs as they resume growth. The live oak leaves may be falling, this is normal, no cause for alarm. The round growths on the leaves are wasp galls, harmless to the tree. Use them for mulch. Paint all wounds on oak trees with pruning paint or latex paint immediately after the wound is made or discovered in order to prevent the spread of oak wilt. Watch for SOPHORA CATERPILLARS on Texas mountain laurel. Use Bacillus thuringiensis (Bt) or malathion to control them.
