What vegetables to plant in June

  1. Plant celery early this month (self-blanching varieties are best for home gardeners). Celery is a heavy feeder, so be sure to plant it in fertile soil.
  2. If you live in a warm-season area, plant sweet potato slips early in the month if you didn’t plant them last month. Sweet potatoes prefer lean, well-draining soil.
  3. Set out transplants of Brussels sprouts. These will mature for a fall harvest.
  4. Transplant okra plants once the soil temperature is greater than 70°F.
  5. Plant tomato transplants in early June.
    • Check for the days to maturity before selecting tomato plants to transplant this month.
    • Choose tomato varieties that’ll produce tomatoes before your first frost.
