How to Check If Sweetcorn Ears Are Ready to Pick
How to Check If Sweetcorn Ears Are Ready to Pick
Judging ripeness is the secret to the very best sweetcorn: plump kernels bursting with sweet, milky juice. Pick too soon and your cobs will be stunted and bland; too late and they’ll turn tough and starchy. Here’s how to know for sure when it’s showtime in your corn patch!
Top Signs Your Sweetcorn Is Ripe
1. Browning Silks
- The tassel-like silks at the end of each ear turn from golden to brown and dry.
- Silks will have started drying for about 1–2 weeks.
2. Full, Firm Ears
- Gently squeeze the ear through its husk: it should feel plump, round, and solid—not thin or doubled-over.
3. Fingernail Kernel Test
- Peel back a small section of husk (near the top of the cob).
- Puncture a kernel with your thumbnail:
- Milky, white sap: Perfect! Pick now.
- Clear, watery sap: Not quite ready—check again in a day or two.
- No juice or doughy kernel: Overripe, starch building up.
4. Uniform Kernel Rows
- Kernels should be swollen, bright, and arranged in neat, regular rows up and down the cob.
5. Ear Position
- Ripe cobs often start to tip slightly downward on the stalk.
How to Avoid Under- or Overripe Corn
- Check every day as soon as you see brown silks. Sweetcorn matures fast, sometimes within just a couple of days.
- Mark your calendar for about 18–24 days after silks first appear—this is when most varieties are ready.
Troubleshooting Unripe or Poorly Filled Cobs
- Harvested too soon: Small, underdeveloped, or tasteless kernels.
- Overripe: Kernels tough, dull, or lose sweetness—use in cooked dishes or preserve.
- Patchy fill: Pollination issue—see our pollination tips to improve results next year.
What To Do Next
- If some plants aren’t ready, leave them and check again tomorrow. Corn on one stalk may ripen at different times.
Pro Tip:
The sweeter the variety, the narrower the picking window. Super-sweet corn is best picked and eaten on the same day!
