Picking summer squash small and often

Squash is often ready 4–8 days after the flower opens, and plants make less new fruit when big squash stay on the vine.

When we suggest this

  • Your noteYou noted the stage: fruit forming or ready to harvest.

What would stop us suggesting it

  • When you note a new stage, or the timing window ends.
  • When you mark it Done or Doesn't apply. "Doesn't fit my setup" stops it for that plant this season.

What to do

  1. Check plants every day or two once fruit starts forming.
  2. Pick zucchini and other long types at about 6–8 inches long and 2 inches across or less. Pick pattypan types at about 3–4 inches across.
  3. Remove oversized squash too, even if you won't use it. If you can't dent the skin with a thumbnail, it's past its best.

What we can't know

  • Which kind you're growing: zucchini, yellow, or pattypan.

Sources give 6–8 in for zucchini and long types (South Dakota State allows up to 10 in) and picking every 1–2 days, daily in very warm weather.

Where this advice applies

All US regions.

Any US garden where summer squash or zucchini is setting fruit.

In very warm weather squash sizes up fastest and may need picking daily.

Exceptions

  • Plants you've marked finished for the season.
  • Squash you're growing on purpose for seed.
