From a meteorological standpoint, September 1 marks the beginning of the fall season.   Fall is officially here on Wednesday, September 23.  However, there is so much going on with gardening now that September is here. 
Here are just a few gardening chores that we need to keep in mind this month.
  1.  Did you have problems with Japanese Beetles this summer?  If so, now is a good time to apply Milky Spore to the lawns.  I think Milky Spore is the best product for controlling the population of the white grub worm which turns into Japanese Beetles.  The white grub worms are eating now in order to get fat before going deep into the ground for the winter.  Milky Spore begins working as soon as it is applied.  Once grubs are infected they will multiply the Spore.  Milky Spore is non-toxic.  It is harmless to food crops, and does not affect pets, beneficial insects, bees, birds, other animals, and even earthworms.  It is a great product for control.  So, do it now and then again in early March.
  2. Did you have problem with the Canker Worm, a.k.a. “Green Inch Worm” this spring eating the leaves on some of your trees and shrubs?  If so, now is best time to begin to win the battle.  You want to keep the wingless female moth from crawling up the trees and laying her eggs.  Apply a product called Tree Tanglefoot to the trunk of the trees.  This sticky substance will trap the female moth thus stopping her in her tracks.  No egg laying = no green inch worms in the spring.
  3. September is a good month to dig up and divide your perennials.
  4. Now is a good time to start planting your cold crop vegetables such as lettuce, spinach, broccoli, cabbage, kale, cauliflower, etc.  If you don’t have a traditional garden it is o.k. to plant these leafy vegetables into your landscape.  These leafy vegetables will give color and texture to your established foundation plants.
  5. September is the first month for the S. O. D. program.  Now is the time to seed or overseed your lawn and apply your first application of a lawn starter fertilizer.  Once you seed – WATER, WATER, WATER daily until the seed has germinated and began to grow.  You must keep the ground moist through this germination period.
  6. Do NO trimming on evergreens or spring blooming shrubs such as azaleas.  Pruning in September will alert the plant to put out new growth.  You do not want new growth at this time.  This tender growth will be hurt will our first fall frost.
Next week I will talk about the S. O. D. fertilizing program and the seeding or overseeding of our cool season fescue lawns.
