Jun 26, 2023 · For medium-sized broccoli seeds, the general rule of thumb is to plant two seeds per hole. These seeds are moderately sized and strike a balance between the larger and smaller varieties. Planting two seeds helps increase the chances of successful germination, especially considering that not all seeds may sprout.
EARLY SPRING CROP: Use early and midseason varieties. Sow 2 seeds per cell in 72-cell plug flats, 3–4 seeds/in. in 20 row flats, or in outdoor beds ¼" deep. Seedlings should be ready to transplant in 3–4 weeks. If possible keep soil temperature 75–80°F (24–27°C) until germination, then reduce air temperature to about 60°F (16°C).

When a head first emerges from the stalk, start monitoring your container every day. The heads can grow really quickly at this stage, and you don’t want to let the buds turn into flowers.

If you have your broccoli seedlings under grow lights, leave them on for 14-18 hours per day. Florescent and classic grow lights should be kept 2 to 3 inches above the plant tops (raise them as your seedlings grow). LED grow lights don’t have to be quite as close to the plants. 6 to 8 inches will suffice.

Set out the transplants in late April and early May, spacing them about 45cm (18″) apart in rows 90cm (3′) apart. One packet sows approx 20m (66′) of row when thinned to a 40-50 cm (16-18″) spacing.
