I swear, summer squash has two modes: tiny and adorable or zucchini the size of a baseball bat. One day, you check on your plants, and everything looks normal. The next, you’ve got squash so big it could be used for self-defense.

I’ve been there—harvesting too late, ending up with watery, seedy squash, and desperately Googling “what to do with overgrown zucchini.” But through trial and (delicious) error, I’ve figured out exactly when to harvest summer squash, how to store it so it stays fresh, and the best ways to cook and preserve it so none goes to waste.

If you want to avoid soggy squash, wasted produce, and missed harvest windows, let’s get into it!

When to Harvest Summer Squash (Timing is Everything!)

Summer squash, including zucchini, yellow squash, pattypan, and crookneck, grows fast. If you’re not checking daily, you might end up with squash so big you have to haul it inside with both arms.

Best Size to Harvest by Type

Squash Type	Best Harvest Size	Why?
Zucchini	6-8 inches long	Tender, firm, and not overly seedy
Yellow Squash	4-7 inches long	Sweet, not tough or watery
Pattypan	2-4 inches across	Best texture and flavor
Crookneck	4-6 inches long	Smooth, not bumpy or hard

Daily Harvest Tip: Once summer squash starts producing, check plants every single day. Squash can double in size overnight—no joke.

How to Harvest Summer Squash Properly

I used to just grab squash and twist it off the plant… until I learned the hard way that this damages the vine. A few best practices will keep your plants producing longer and prevent breakage.

Use Clean, Sharp Tools – A sharp knife or garden shears works best. (Affiliate link opportunity: garden shears)
Cut at the Stem – Leave about ½ inch of stem attached to prevent premature rotting.
Harvest in the Morning – Squash holds the most moisture early in the day.

Pro Tip: Frequent harvesting encourages more production! If you let squash sit too long, the plant assumes it’s done its job and stops making new fruit.

What to Do with Overgrown Squash

So, you missed the ideal harvest window, and now you have monster zucchini on your hands? No worries—I’ve got you covered!

Signs of Overgrown Squash:

• Bulging in the middle
• Thick, tough skin
• Large, developed seeds
• Watery or spongy texture

How to Use It Instead of Tossing It:
Make Zucchini Bread – The extra moisture actually works in your favor!
Grate & Freeze for Baking – Perfect for later use.
Stuff It & Bake It – Scoop out seeds, fill with stuffing, and bake.
Turn It into Fritters or Hash Browns – Shred it, squeeze out excess moisture, and fry it up!
Make Zucchini Noodles (Zoodles) – A spiralizer (Affiliate link opportunity: spiralizer for zoodles) makes easy, low-carb pasta alternatives.

How to Store Summer Squash for Maximum Freshness

Nothing’s worse than a soggy, limp zucchini in the fridge. Luckily, I’ve tested a few methods, and these are the best ways to keep summer squash fresh:

Short-Term Storage (Up to 1 Week)

Store in the Crisper Drawer – Place whole, unwashed squash in a perforated plastic bag or paper towel to absorb moisture. (Affiliate link opportunity: reusable produce bags)
Keep it Dry – Excess moisture = faster spoilage.

What NOT to Do:
Don’t wash squash before storing—it speeds up rot.
Don’t store squash in a sealed plastic bag—it needs airflow!

Long-Term Storage (Freezing & Preserving)

If you have a massive squash harvest, freezing or dehydrating is the way to go.

How to Freeze Summer Squash

Wash & Slice – Cut into rounds or cubes.
Blanch for 2-3 Minutes – Quickly boil, then transfer to ice water.
Drain & Flash Freeze – Spread pieces on a baking sheet to freeze before transferring to freezer bags. (Affiliate link opportunity: freezer-safe storage bags)

Shelf Life: Up to 1 year!

How to Dehydrate Summer Squash

Slice thinly (¼ inch thick)
Lay out on dehydrator trays (Affiliate link opportunity: food dehydrator)
Dry at 125°F for 6-10 hours until brittle
Store in airtight containers

Dehydrated squash is great for soups, stews, or even homemade zucchini chips!
