Lemon squash can get quite big, and depending on the variety, they can grow anywhere from 10 to 12 inches long and weigh between 3 and 5 pounds.
If you’ve ever wondered how big lemon squash get, the answer really depends on the type you’re growing and how long you let them mature on the vine.
Some smaller varieties stay compact at around 4 to 6 inches, while larger types can surprise you with their size if left to fully develop.
In this post, we’ll look at how big lemon squash get, what factors affect their size, and how to tell when they’re ready to harvest.
How Big Do Lemon Squash Get?
Lemon squash generally grow to be about the size of a large lemon or a small grapefruit, though some can get bigger.
On average, a mature lemon squash measures between 3 and 4 inches in diameter and weighs around 1 to 2 pounds.
However, if you leave them on the vine longer, they can keep growing and reach 5 to 6 inches across and weigh up to 4 or 5 pounds.
The size of your lemon squash depends on several key factors that we’ll break down below.
1. Variety Matters Most
The variety of lemon squash you plant plays the biggest role in how big they get.
Some cultivars are bred to stay small and tender, while others are known for producing larger fruit.
If you’re growing a compact variety, don’t expect your lemon squash to get massive no matter how long you wait.
On the other hand, larger varieties can easily exceed 6 inches if given enough time and the right conditions.
2. Growing Conditions Affect Size
How big lemon squash get also depends on how well they’re grown.
Lemon squash thrive in full sun with rich, well-draining soil and consistent watering.
When they get plenty of nutrients and water, they grow bigger and healthier.
Poor soil, drought, or too much shade can stunt their growth and keep your lemon squash smaller than they could be.
3. Time on the Vine
The longer lemon squash stay on the vine, the bigger they get.
If you harvest early, your lemon squash will be smaller and more tender.
But if you leave them to mature fully, they can grow much larger and develop a tougher skin.
Just keep in mind that bigger isn’t always better when it comes to lemon squash, as oversized ones can become seedy and less flavorful.
What Determines the Final Size of Lemon Squash?
Several factors work together to determine how big lemon squash get.
These include genetics, growing conditions, and how long you let them mature.
Understanding these factors helps you decide when to harvest and what size to expect.
1. Genetics Set the Limit
Every lemon squash plant has a genetic ceiling for how big its fruit can get.
You can’t make a small variety produce giant lemon squash no matter how perfect your garden is.
So check your seed packet or plant tag to know what size to expect from your specific variety.
2. Soil Fertility and Watering
Healthy soil with plenty of organic matter gives lemon squash the nutrients they need to reach their full size.
Consistent watering is also key, as drought stress can cause lemon squash to stay small and develop poorly.
Mulching around your plants helps retain moisture and keeps the soil temperature steady.
3. Competition and Spacing
If your lemon squash plants are crowded, they compete for water, nutrients, and sunlight.
This competition can limit how big lemon squash get.
Giving each plant enough space to spread out helps them grow bigger, healthier fruit.
4. Pests and Diseases
Pests like squash bugs and diseases like powdery mildew can weaken your plants.
When lemon squash plants are stressed by pests or disease, their fruit often stays smaller.
Keeping a close eye on your garden and addressing problems early helps your lemon squash reach their potential size.
When to Harvest Lemon Squash for the Best Size
Knowing when to harvest is just as important as knowing how big lemon squash get.
For tender, flavorful lemon squash, pick them when they’re 3 to 4 inches in diameter.
If you want bigger lemon squash, you can let them grow to 5 or 6 inches, but be prepared for a tougher texture and more seeds.
The skin should be firm and glossy, and you should be able to pierce it easily with your fingernail.
1. Check the Skin
A ripe lemon squash has smooth, shiny skin that’s firm to the touch.
If the skin feels hard or dull, your lemon squash may be overripe.
For the best eating quality, harvest when the skin is still tender enough to scratch with your thumbnail.
2. Watch the Calendar
Most lemon squash varieties are ready to harvest about 50 to 60 days after planting.
Keep track of when you planted so you know when your lemon squash are approaching their prime size.
Harvesting regularly also encourages the plant to keep producing more fruit.
So, How Big Do Lemon Squash Get?
Lemon squash typically get to be about 3 to 4 inches in diameter, though they can grow up to 6 inches or more if left on the vine.
How big lemon squash get depends on the variety, growing conditions, and how long you let them mature.
For the best flavor and texture, harvest your lemon squash when they’re small to medium-sized.
If you want bigger lemon squash, give them time, space, and plenty of care, and you’ll be rewarded with an impressive harvest.
