August: To Do in the Garden

by Gary Crispell EMGV

Already it’s August! We must be having fun ‘cause the time sure is flying. It’s a good thing we’re supposed to be staying home mostly. I surely don’t have time to go anywhere. Nature abhors a vacuum and so, like most folks, I’ve found plenty to do without going anywhere.

I don’t know about your yard, but ours didn’t get a drop of rain from the first week in July until the 29th.  The Accidental Cottage Garden looks like an accident happened. It is sad. There are a few black-eyed susans (Rudbeckia fulgida) hanging on along with some coreopsis (C. lanceolata and C. verticilata). The butterfly weed (Asclepeis tuberosa) and a late blooming daylily (Hemerocalis x August Flame) are making an orange show and some blanket flowers (Galardia pulchella) are thumbing their noses at the droughty-ness.

We stuck some tomatoes in Earth Boxes in front of the kitchen window and they are very happy. Then there’s the basil … Last year we had three plants. (I like basil.) This year we have 10,378 – more or less.  Basil as a weed species is a novelty to me!

Anyway, here are a few things you can do in your garden when the heat index is not in the stratosphere.

Lawn Care
– Check the lawn for grubs.  If you find some, treat with an appropriate insecticide. If you do not find any be grateful and put the sprayer away.
– Late in the month prepare any areas that need to be seeded with cool season grass (tall fescue, bluegrass).

– Give your strawberries a shot of nitrogen fertilizer.
– DO NOT fertilize trees or shrubbery until December.

– Sow pansy seeds this month in flats, indoors, to transplant to the landscape in September.
– Perennial seeds, such as hollyhock (Alcea rosea), larkspur (Delphinium) and Stokes aster (Stokesia Laevis) can be sown now, outdoors, for healthy plants in the spring.
– Repot more house plants.
– Plant a fall garden with beets, Chinese cabbage, cucumbers, kale, kohlrabi, lettuce, mustard, radish, rutabaga, squash & turnips.

Nada! Nope. Don’t. No pruning of trees or shrubs until November. In case of hurricane damage disregard the above admonition.

– Same stuff as last month. Look for spider mites on coniferous evergreens (juniper, arborvitae, etc.) and lace bugs on azaleas and pyracantha.
– Continue rose spray program and weekly spraying of fruit trees and bunch grapes.
– Watch for worms on cruciferous vegetables (broccoli, cabbage, cauliflower) and borers on squash.  Spray only if necessary. Follow the label instructions.

You may still take cuttings of shrubs.

More things to do if you just can’t get enough of the August heat:

  • Read our Tomato Grafting Project page and up your game for next year’s tomato crop.
  • Make sure your Landscape Plan is up to date especially if you plan to modify the landscape this fall.
  • Keep running up the water bill when the August thunderstorms skip your house.
  • Build a compost bin.
  • Dig Irish potatoes.
  • Stay cool and hydrated.
  • Wear your mask and wash your hands.

September and October will soon be at hand and we can do all those things in relative comfort.
