- Plant broccoli during the cool weather of early spring and fall. Grow it in containers or an in-ground garden.
- Space broccoli plants according to the label (usually 18 inches apart). Choose a location with full sun, easy access to water, and fertile soil with a pH between 6.0 and 7.0 (amend soil with lime if necessary).
- Before planting, improve native soil by working in several inches of compost or other rich organic material.
- Keep soil moist by giving broccoli plants 1 to 1.5 inches of water per week.
- Make the most of your broccoli growing efforts by regularly feeding with a continuous-release plant food.
- Lay down a thick layer of organic mulch made from finely ground leaves or bark to preserve soil moisture and prevent weeds.
- Timing and temperature are critical for successful growth. The ideal growing temperature range is 65 to 80° F.
- Harvest broccoli when the center crown is full of tiny, green, tightly-packed buds.
- Plant seeds 1/4 to 1/2 inch deep, or set transplants slightly deeper than they were grown originally.
- Plant or thin seedlings 18 to 24 inches apart in the row and allow 36 inches between rows.
- Broccoli plants grow upright, often reaching a height of 2 1/2 feet.
- Space plants one foot apart in all directions in beds.
