Broccoli is not a fast grower. You can start broccoli indoors 4-6 weeks before transplanting. Broccoli does best in full sun. So pick an area which receives at least 8 hours of full sunlight. Add compost and manure in the garden bed. This will ensure that the soil is rich with nutrients. Plant broccoli in spring or fall.
Broccoli plants love moisture so make sure that the soil is nice and moist. Look out for weeds and make sure that the plant is free of weeds and insects.
