How Big Do Lemon Squash Get

Lemon squash can get quite big, and most varieties reach full size in about 50 to 70 days after planting.
 
If you’ve ever wondered how big do lemon squash get, the answer depends on the variety, growing conditions, and how long you leave them on the vine.
 
On average, a mature lemon squash will grow to be about 4 to 6 inches in diameter and weigh anywhere from 1 to 3 pounds.
 
Some giant heirloom types can push past 5 pounds if you let them keep growing.
 
In this post, we’ll look at exactly how big lemon squash get, what affects their final size, and how to tell when they’ve reached their peak.
 
Let’s dig in.
 

How Big Do Lemon Squash Get?

Lemon squash typically get as big as a large grapefruit or a small melon, but there are a few factors that decide their final size.
 
Here’s what influences how big your lemon squash will get:
 

1. The Variety You’re Growing

Different lemon squash varieties have different genetic size limits.
 
Some compact bush types stay smaller, usually maxing out around 3 to 4 inches across.
 
Heirloom vining types, on the other hand, can get much bigger and often reach 6 inches or more in diameter.
 
So before you ask how big do lemon squash get, check your seed packet because the variety sets the ceiling.
 

2. Growing Conditions and Soil Quality

Lemon squash get bigger when they’re grown in rich, well-drained soil with plenty of organic matter.
 
If your soil is poor or compacted, the plant will still produce fruit, but the squash won’t get as big.
 
Consistent watering also plays a huge role because squash are thirsty plants.
 
When they get steady moisture, the fruit swells faster and reaches a larger size.
 

3. Sunlight and Temperature

Lemon squash need at least 6 to 8 hours of direct sunlight to get big.
 
Warm weather speeds up growth, while cold snaps can stunt the fruit.
 
If temperatures drop too low, the squash may stop growing altogether, no matter how long you leave it on the vine.
 
That’s why lemon squash get their biggest in full sun and consistent warmth.
 

4. Time Left on the Vine

The longer you leave lemon squash on the vine, the bigger they’ll get, up to a point.
 
Young lemon squash are usually harvested at 2 to 3 inches for a tender, mild flavor.
 
But if you want to know how big do lemon squash get when fully mature, you’ll need to wait until the skin hardens and the color deepens to a bright yellow.
 
At that stage, they can easily reach 4 to 6 inches and weigh a couple of pounds.
 

5. Spacing and Plant Health

Crowded plants compete for water and nutrients, which means smaller fruit.
 
Give your lemon squash plenty of room, usually 2 to 3 feet apart, so each plant can thrive.
 
Healthy plants with strong vines also produce bigger squash because they have more energy to pump into the fruit.
 
So if you want to maximize how big lemon squash get, keep your plants well-spaced and pest-free.
 

What’s the Average Size of a Lemon Squash?

The average lemon squash is about the size of a softball, roughly 3 to 4 inches in diameter.
 
At that size, it usually weighs between 1 and 2 pounds.
 
But when conditions are ideal, lemon squash can get as big as 6 inches across and tip the scales at 3 pounds or more.
 
So the range really depends on how you grow them and when you pick them.
 

How to Tell When Lemon Squash Are Fully Grown

Knowing when lemon squash are fully grown helps you harvest at the right time.
 
Here are the signs to look for:
 

1. Firm, Glossy Skin

A fully grown lemon squash will have firm skin that’s glossy and bright yellow.
 
If the skin still looks pale or feels soft, it needs more time on the vine.
 

2. A Thump Test

Give your lemon squash a gentle thump.
 
If it sounds hollow, that’s a good sign it’s fully grown and ready to pick.
 

3. Heavy for Its Size

Pick up your lemon squash and feel the weight.
 
A mature one will feel heavy for its size, which means it’s packed with moisture and fully developed.
 

4. Dried Stem

When the stem starts to dry out and turn brown, your lemon squash is usually done growing.
 
That’s the plant’s way of saying the fruit has reached its full size.
 

So, How Big Do Lemon Squash Get?

Lemon squash get as big as 4 to 6 inches in diameter and can weigh anywhere from 1 to 3 pounds or more.
 
The final size depends on the variety, growing conditions, sunlight, and how long you leave them on the vine.
 
If you give your lemon squash rich soil, steady water, and plenty of sun, you’ll be rewarded with bigger, healthier fruit.
