How to Plant and Grow Patty Pan (Scallop) Squash

Cucurbita pepo

If you love summer gardening and usually stick to zucchini and yellow crookneck squash, why not add some interest to your patch with delightful looking and delicious scallop squash?

Also known as patty pan squash, these beautifully shaped cucurbits take this common name from the scallop-edged pans that were intended for making small cakes or pies.

They grow on compact bush plants rather than vines, taking up less room in the garden than some of the other summer squash varieties.

Patty pan squash are a group of varieties or cultivars of the species Cucurbita pepo.

This is the same species responsible for many other edibles of the summer garden – including pumpkins, crooknecks, straightnecks, acorn squash, vegetable marrows, zucchini, and many ornamental gourds!

In this article you’ll learn everything you need to know about growing patty pan squash, from seed to harvest to plate.

Here’s what we’ll cover:

Also known as granny, custard, button, schwoughksie, or pattypan squash, as well as cymlings, scallopini, or patissons, these veggies are native to the Americas, and made their way to Europe in the 1500s.

These days these flying saucer shaped veggies are rare to find for purchase, even at farmer’s markets, so if you want to enjoy cooking with them, you’ll likely need to grow your own!

Boasting some of the most beautiful cultivars, patty pan squash have an old fashioned appearance, combined with a familiar flavor and succulent texture.

Although they may look unusual, their growing requirements aren’t very different from crooknecks or zucchini.

Propagation

Consider sketching out your design in a garden planner ahead of time.

Here’s how to proceed:

Direct Sowing

To direct sow seed into the garden:

1. Prepare the growing area by removing any weeds, mixing a few shovels of compost into the soil, and watering down the planting area the day prior to sowing.
2. Unless you are in an arid climate, mound the soil up slightly in the center of the planting area.
3. Poke two to three holes, an inch deep, in the center of the planting area, insert one seed per hole, then close the soil over the seeds and pat it down.
4. Water in the seeds, and if conditions are dry, irrigate daily until germination. Germination should take place in five to 10 days.
5. Thin to one to two seedlings per planting, removing the weakest ones.

Gradually decrease watering as young plants become established.

How to Sow Indoors

When possible, opt to direct sow rather than growing starts to transplant.

However, if you have a short growing season, you may need to start seeds indoors two to four weeks before the last frost date.

Before you start, gather up your supplies: seeds, seed starting growing medium and pots or trays. You may also need a heat mat, like this one, available via Amazon.

1. Fill pots nearly full with moist growing medium, leaving a half inch to an inch gap at the top.
2. Poke a hole into the center of each pot or tray cell, then insert one seed one half to one inch deep.
3. Squeeze the growing medium closed over the seed and pat to ensure good contact between the seed and the medium.
4. Place the pots or tray near a window where plants will be exposed to six to eight hours of direct sunlight after they germinate, or under a grow lamp, and keep them at a temperature of 70 to 95°F.
5. Keep the growing medium moist. Expect germination in five to 10 days.

After your last frost date, harden off the seedlings and transplant into the garden.

Transplanting

Whether you’ve grown your own seedlings indoors or purchased nursery starts, here’s how to put them in the ground:

1. Prepare the growing area by removing weeds or faded vegetation from last year’s garden.
2. Water the planting area the day before transplanting.
3. Dig a hole in the garden soil that is twice as wide and deep as the nursery pot.
4. For seedlings in biodegradable pots, break off the rim of the pot and discard, then insert the pot into the hole. For those in plastic pots, carefully remove the plant from the pot without disturbing the roots, and insert the root ball into the hole.
5. Replace soil around the root ball but take care not to cover the crown of the plant.

Water in well, and irrigate daily for the next week if conditions are dry.

How to Grow

Growing patty pan squash is much the same as growing other summer squash.

Here’s what you’ll need to know:

Climate and Temperature

Patty pan squash are warm season crops – that means they won’t tolerate frost or freezing temperatures.

Sow or transplant after all risk of frost has passed, and harvest before frost returns in fall – or use a floating row cover to extend the growing season.

Light 

Like other cucurbits, these summer squash plants need a full sun location in the garden.

Situate the growing patch where it will receive at least six to eight hours of direct sunlight per day.

Soil

Patty pan squash grows happily in typical loamy garden soil, thriving in a pH range of 5.8 to 6.8.

Water

As a general rule, water patty pans infrequently, but deeply.

You may have heard that scallop squash plants need one to two inches of water a week – and that’s true, but only if the temperatures are in the 70s.

How often you’ll need to water depends not just on the temperature, but also on how sunny it is.

In dry, hot weather, you may need to irrigate two or three times a week.

Fertilizing

If you work compost into your soil before sowing or transplanting, you may not need to add additional fertilizer later in the growing season.

Cultivars to Select

Are you ready to think about which type of scallop squash to grow? Here are a few suggestions to get you started:

Benning’s Green Tint

‘Benning’s Green Tint’ is an heirloom cultivar first introduced in Washington, DC, in 1914, that produces light green to creamy white fruits.

Needing just 52 days to reach maturity, ‘Benning’s Green Tint’ should be harvested at two to three inches wide.

‘Benning’s Green Tint’

Purchase packs of ‘Benning’s Green Tint’ in an assortment of sizes from High Mowing Organic Seeds.

Gelber Englischer

A German heirloom, ‘Gelber Englischer’ produces fruits that are cream colored to lemon yellow, and are shaped rather irregularly.

This variety is best harvested at two to four inches wide, and needs 55 to 60 days to reach maturity.

‘Gelber Englischer’

You’ll find packs of 20 ‘Gelber Englischer’ seeds available at Botanical Interests.

Jaune et Vert

‘Jaune et Verte’ is a yellow and green patty pan cultivar with radiating stripes that is best harvested at two to three inches wide.

This French heirloom is slower to mature than some of the others, requiring 60 to 90 days to produce fruit.

‘Jaune et Vert’

Pick up ‘Jaune et Vert’ seeds in a selection of pack sizes from Eden Brothers.

Maintenance

When growing patty pan squash, keep the area around the bushes free from weeds, especially when they are young and trying to get established.

However, after the plants are a bit bigger, they will hold their own and won’t be bothered if you get behind on weeding chores.

In the meantime, one way to help prevent weeds from growing is to apply mulch around plants.

And there are many different materials you can use for mulch, such as leaves or straw.

Managing Pests and Disease

I’m sure you’re looking forward to plucking that first patty pan squash off the bush.

But to ensure an abundant harvest, you’ll also need to be on the lookout for pests and diseases.

Herbivores

Insects aren’t the only types of unwanted visitors you might find eating your patty pan squash plants:

Deer

If there are deer in your area, your garden will be at risk from them unless you let them know they are not invited.

A deer fence can keep these four legged browsers away from your crop – but there are other preventative actions you can take as well, as detailed in our guide.

Rabbits

Rabbits only seldom choose to nibble on these plants, but if you’ve previously had visits from these mammals to your garden, you might want to protect the plants.

Learn how to keep rabbits out of the garden here.

Insects

Expect the same types of critters to frequent your patty pan squash plants as the pests that typically target zucchini.

Here are a few potentially bothersome insects to look out for:

Aphids

Often, an aphid infestation can be controlled simply by spraying them off the plant with a strong jet of water from a garden hose. Repeat weekly until the aphids are gone.

Our guide to dealing with aphids has more information.

Squash Bugs

Squash bugs are true bugs that bite into the leaves of cucurbit plants, damaging the tissue, and causing them to wilt, and eventually die.

Manual control is a slightly time consuming but effective method of removing these pests.

And also keep your eye out for nymphs that are bright gray or light green with spindly black legs.

Read our guide to controlling squash bugs to learn more.

Whiteflies

Does a cloud of white flies greet you when you enter your garden patch? Sounds like you might have a whitefly problem.

In spite of the name, they are not actual flies, these sucking insects are related to scale and mealybugs.

Learn about how to deal with whiteflies here.

And as part of an organic approach to protecting crops from pests, consider using companion plants.

Disease

In addition to pests, you’ll also want to be aware of a few diseases that affect patty pan squash:

Blossom-End Rot

This condition affects patty pans in the same way that it does zucchini.

Read our guide to blossom-end rot in zucchini to learn more.

Downy Mildew

If you have noticed yellow or light green angular shaped spots on leaves, accompanied by a downy fuzz, then you’re probably looking at downy mildew!

This fungal-like disease thrives in humid conditions, and can be prevented by watering at the base of the plant instead of overhead, such as with sprinklers.

Powdery Mildew

Are you seeing a white powdery substance on the leaves of your patty pan plant?

Powdery mildew, a fungal disease that spreads in humid conditions, is likely to blame. It’s very common in the summer garden and can be treated organically.

Read our guide to powdery mildew here.

Harvesting

Here’s the fun part! When the fruits are about two to three inches wide, it’s time to harvest.

When the size is right, grab a clean knife or pair of garden pruners and cut the stem from the bush.

Why should you pick fruits when they are so small?

As they grow larger, the seeds inside will become tough. You can still eat the fruits at this later stage, but you will want to remove the hard seeds from the interior first.

Preserving

If you grow more patty pan squash than you can eat at once, you might want to consider preserving some of your harvest.

Freezing is of course one option. If you want to freeze the raw vegetable, take the time to blanch it first for the best results.

Finally, don’t overlook the wonders of dehydration. Dried garden vegetables can provide ingredients for winter soups or be transformed into fun snacks.
