Seasonal tips

  • Succession sow fast-maturing crops like French marigolds or nasturtiums every two weeks for continuous blooms.
  • Thin out crowded seedlings of summer squash and pole beans to ensure strong air circulation.
  • Apply a light layer of compost around heavy feeders like okra and melons to boost nitrogen levels.
Keep watch

Pest & disease watch

  • Monitor for aphids on the new tender growth of basil and borage.
  • Watch for cucumber beetles attacking your young cucumbers, squash, and melon vines.
  • Check zinnia stems for spider mites as heat increases later in the week.
Water

Watering this week

Water deeply in the early morning to keep foliage dry and reduce fungal risks on these warm-weather crops.

One more thing

Harvest your watermelons by checking for a creamy yellow spot underneath where they touch the ground, indicating ripeness.
