August Garden To Dos
General Garden Care
- Water all trees/shrubs deeply at least once every three weeks if in the ground. Plants in containers may need daily water to survive.
- Keep compost piles slightly moist, turn frequently.
- Pick up and compost fallen fruit.
- Stay cool—garden in the early morning or late afternoon. Avoid mid-day sun!
- Prune berries when fruiting is finished.
- Prune Apricots before rains to prevent Eutypa lata fungus from infecting pruning wounds.
- Prop up fruit tree branches if needed to help with the fruit load.
- Raise squash and cucumbers off the ground so pests cannot tunnel into the fruit.
- Start seeds of fall vegetables: direct seed beets, onions, Swiss chard, carrots, parsley, spinach, peas; radishes, lettuce.
- Start containers of broccoli, Brussels sprouts, cabbage, cauliflower, kale.
- Plant a last row of corn to ripen in the fall.
- Harvest vegetables frequently.
Flowers & Landscaping
- Plant fall blooming bulbs (Crocus, Lycoris).
- Deadhead spent blossoms to keep plants blooming.
- Divide bearded iris rhizomes if over three years of age.
- Fertilize spring blooming plants- they are setting their buds now.
- Fertilize warm season lawns.
- For fall color, plant seeds of calendulas, Icelandic poppies, stock, snapdragons, sweet alyssum, sweet peas, violas.
- Cut and dry summer flowers & herbs in dry shade.
- Cut back straggly early summer color plants.
- Fertilize chrysanthemums at the end of the month.
- Drippy acorns? Drippy acorns are caused by a bacterium similar to Erwinia amylovora, the organism that causes Pear Fireblight. There is little to be done, just keep the plants as stress-free as possible and clean up fallen leaves regularly.
