Waltham 29 Broccoli Planting Instructions:
1. Timing: While it can be planted in the spring, Waltham 29 truly shines as a fall crop. Start seeds indoors 10-12 weeks before your first expected autumn frost.
2. Sowing: Sow seeds 1/4 to 1/2 inch deep. If starting indoors, transplant to the garden once the seedlings have at least two sets of true leaves.
3. Care: Broccoli needs plenty of nitrogen and consistent water. Mulch the base of the plants to keep the soil cool and moist, which prevents the heads from "bolting" or flowering too early.
4. Harvesting: Cut the main head when it is firm and the buds are tightly closed. Cut at an angle to allow water to run off the stem, which encourages the growth of side shoots for a secondary harvest.
5. Pests & Disease: Keep an eye out for cabbage worms and root maggots. Using a floating row cover can protect the young plants from pests while they are establishing.
