Things to do in August

  • Optimal time for establishing a new lawn is August through mid-September.

  • Prune cherry trees before fall rains begin to allow callusing in dry weather. This will minimize the spread of bacterial canker.

  • First week: If necessary, second spray of filbert trees for filbertworm.

Question of the Week

We have a large infestation of flea beetles, centralized in our garden. There are millions of the beetles. We put 1000 ladybugs out last night. The garden is approximately 60x100 ft. Do we need more lady bugs or is there another approach to kill these beetles?
