How to Harvest Swiss Chard So It Keeps Growing
Swiss chard is a cut-and-come-again leafy green, meaning you can harvest it multiple times without killing the plant. By using the right harvesting method, you can keep chard producing tender leaves for months.
When to Start Harvesting
Begin harvesting when leaves are 6–8 inches long and stalks are firm. Smaller leaves are tender and mild, while larger leaves have a stronger flavor.
The Best Harvesting Technique
- Pick from the outside in: Remove the oldest, outer leaves first, leaving the central growth untouched.
- Cut or snap cleanly: Use scissors, a sharp knife, or gently snap stalks at the base to avoid damaging the crown.
- Harvest regularly: Pick every few days to encourage continuous growth and prevent plants from going to seed.
How Much to Take
Never remove more than one-third of the plant at a time. This ensures enough foliage remains for photosynthesis and regrowth.
Encourage Regrowth with Good Care
- Water deeply: Keep soil evenly moist to support leaf production.
- Fertilize lightly: Side-dress with compost or feed with diluted fish emulsion every few weeks.
- Control pests early: Aphids, slugs, and leaf miners can slow regrowth—inspect plants regularly.
Note from My Experience
In my raised beds, I’ve kept a single Swiss chard planting productive for over nine months by harvesting outer leaves twice a week. By avoiding damage to the center, the plants continuously push out fresh, tender growth.
Takeaway: Harvest from the outside, leave the center intact, and care for plants after cutting—your Swiss chard will reward you with months of fresh leaves.
