How do you harvest broccoli to encourage regrowth?

Correct harvesting techniques are the key to broccoli's regrowth ability. When you cut the main head correctly, it tells the plants to produce side shoots. I have harvested reliably for over 4 months using this same technique. The initial cut is the first harvest that prepares the plant for a second production. Correctly done, it will minimize stress on the plant and the potential for disease to infect your plants.

Central head harvesting needs angled cuts with sterilized tools. Cut stems at an angle of exactly 45° and 5-6 inches below the head. This prevents stagnant water in the stem. I prefer using bypass pruners, and I dip them in an alcohol solution. Clean cuts heal faster and redirect energy into the lateral buds. Damaged stems totally inhibit regrowth.

Side shoot harvesting requires different precision. Wait until shoots are 2-4 inches with tight buds. Use floral snips and cut ¼ of an inch above the leaf axils. I harvest the largest shoots first every 3-5 days. Removing something continuously signals the plant to produce more. Ensure that you do not break budding shoots of neighbors.

Post-harvest care provides continued growth. Water deeply twice a week to maintain moisture at all times. Apply nitrogen fertilizer weekly. I use a fish emulsion solution. Remove yellowing leaves immediately to focus energy. These methods allow for more harvests.

Sustainable management of your garden also provides you with a longer regrowth window. Keep temperatures from 60-75°F and use shade cloth when temperatures reach 80°F. Below 50°F, you will need to use row covers. I also heavily mulch to insulate the soil and regulate its temperature. When conditions are right, plants can devote a network of energy to creating new shoots.
