Prof. Samuel Fitzgerald, Ph.D.Kale's unique regrowth capacity makes it a popular garden vegetable for continual harvesting. When harvested correctly and using the cut-and-come-again method, any leaves can regrow in a few days. To promote regrowth of kale, cut the outer leaves with a knife 1-2 inches from the base, while preserving the central bud. Be sure to water the plant regularly and feed it once a month to continue harvesting for months.
Harvesting Technique
- Cut position: Always remove outer leaves first
- Bud protection: Never damage the central growth point
- Timing: Harvest morning after dew dries for quick healing
- Frequency: Limit to twice weekly for sustained production
Nutrition & Water
- Fertilizing: Apply fish emulsion every 3-4 weeks
- Water depth: Soak soil 6 inches deep after harvesting
- Mulching: Maintain 2-inch straw layer for moisture retention
- Soil health: Test nitrogen levels monthly during regrowth
Steer clear of regrowth errors that injure plants. Cutting too close to the stem can open the plant up to disease. Harvesting while the plants are wet spreads fungal spores. Overcollecting plants will permanently weaken them. I try to keep my harvest to ⅓ of the leaves a week. This keeps the plants healthy.
Maximize regrowth potential with seasonal modifications. Provide afternoon shade when the air temperature exceeds 85°F. Provide frost protection when the air temperature drops below 25°F to prolong harvests at the end of the season. Rotate harvest zones around the plant. My kale yields 20% more leaves by following these practices!
