Why Plant in September?

september is an ideal time for planting fall vegetables because it allows crops to mature in the cooler, more predictable weather of autumn. This reduces the risk of heat stress, pests, and diseases, leading to healthier plants and more abundant yields.

1. Leafy Greens: Spinach, Kale, and Swiss Chard

These cold-hardy vegetables thrive in cooler temperatures, making them perfect for September planting.

  • Spinach: Choose a variety like ‘Bloomsdale‘ for its cold tolerance and quick growth. Plant seeds directly in the garden, spacing them about 2 inches apart. Spinach will mature in 6-8 weeks, providing a nutritious addition to your fall meals.
  • Kale: Varieties like ‘Lacinato‘ and ‘Red Russian’ are excellent choices. Sow seeds 1/4 inch deep and 12-18 inches apart. Kale can tolerate frost, improving its flavor as temperatures drop.
  • Swiss Chard: This versatile green can be harvested in as little as 4-5 weeks. Plant seeds 1/2 inch deep and 4-6 inches apart. Swiss chard is also frost-tolerant and can be harvested well into late fall.

2. Root Vegetables: Carrots, Beets, and Radishes

Root vegetables are well-suited for fall planting because they can be harvested even after the first frost.

  • Carrots: Plant varieties like ‘Nantes‘ or ‘Danvers‘ in well-drained soil. Sow seeds 1/4 inch deep and thin seedlings to 2-3 inches apart. Carrots will be ready to harvest in 10-12 weeks.
  • Beets: ‘Detroit Dark Red‘ is a popular fall variety. Plant seeds 1/2 inch deep and 3-4 inches apart. Beets are ready for harvest in 8-10 weeks.
  • Radishes: Quick-growing radishes like ‘Cherry Belle‘ can be harvested in as little as 3-4 weeks. Plant seeds 1/2 inch deep and 1 inch apart for a continuous supply.

3. Brassicas: Broccoli, Cauliflower, and Brussels Sprouts

 Brassicas are ideal for fall planting as they thrive in cooler weather and even benefit from a light frost.

 

  • Broccoli: Plant ‘Nature jims sprouts ‘ or ‘Purple Sprouting‘ varieties. Sow seeds 1/2 inch deep and space plants 18-24 inches apart. Broccoli requires consistent moisture and full sun to thrive.
  • Cauliflower: Choose a variety like ‘Snowball‘ for fall planting. Sow seeds 1/2 inch deep and 24 inches apart. Cauliflower is sensitive to temperature changes, so consistent care is key.
  • Brussels Sprouts: Plant ‘Long Island Improved‘ for a reliable fall crop. Space plants 18-24 inches apart and provide support as they grow. Brussels sprouts will mature in 90-100 days.
