Seasonal tips

  • Finish all outdoor planting by mid-August to ensure crops mature before the early September frost.
  • Apply a thick layer of mulch over wintering perennials to protect roots from extreme lows down to -45°F.
  • Clear fallen leaves and debris to prevent overwintering pests and diseases for next spring.
Keep watch

Pest & disease watch

  • Monitor for aphids on your Cleome and French Marigold stems as temperatures cool.
  • Check Lettuce heads for leaf miners or slugs before the first hard frost arrives.
  • Watch for powdery mildew on any remaining green foliage in damp, cool conditions.
Water

Watering this week

Water deeply but infrequently now that soil is cooling and evaporation has slowed significantly.

One more thing

Gather your fresh-cut flowers like Spider Flower to bring vibrant color indoors while the garden sleeps.
