How many times can you harvest from one plant?

Prof. Martin Thorne, Ph.D.A broccoli plant provides several opportunities for harvest, starting with the main head, followed by numerous side shoots. If done properly, you can harvest 1 primary head and 10 - 35 side shoots over the span of 2 - 4 months. My personal record with a single Broccolini plant has been 42 side shoots. Productivity is highly variable, depending on the variety and the level of ongoing care.
Variety selection has a huge effect on total yields. Calabrese types entice 10-15 side shoots after the main head. Broccolini types yield 25-35 tender shoots. Purple sprouting broccoli gives you 15-20 flavorful shoots. Each type has a unique growth habit, which has implications for harvesting frequency and permanence.
Cutting Technique
- Main Head: Cut at 45° angle 5-6 inches below head
- Side Shoots: Snip ¼ inch above leaf axils when 2-4 inches
- Frequency: Harvest shoots every 3-5 days for continuous production
Productivity Boosters
- Fertilization: Apply nitrogen-rich feed weekly after main harvest
- Water Management: Maintain consistent soil moisture without saturation
- Pest Control: Prevent damage to growing points for uninterrupted regrowth
With proper technique, harvest duration expands quite a bit. Except for in rare situations, most plants will produce for 8-12 weeks after their initial harvest. I have managed plants for 16 weeks under almost perfect conditions. Temperature control is crucial. If temperatures are above 80 degrees, production will be shortened, while temperatures between 60 and 75 degrees will lengthen production.
The regrowth potential of plants declines when they deplete their energy reserves. When regrowth comes from smaller shoots and yellowed leaves, the plant is depleting its reserves. I will rotate the plant every four months and observe when my nutrients are depleted, indicated by slow regrowth. Keep track of your observations to determine when each variety's peak production cycle occurs.
Maximize your yields with the following expert tips! -Choose varieties that make sense for your climate. -Check your plant and shoot development daily. -Harvest early developing shoots first to encourage more growth. -Keep your plants healthy with consistent care. If you take care of your plants, they will continue to produce for you for months to come.
