What You Need to Know About Squash

There are many names for squash. There is squash that is widely used for savory cooking. Some varieties are also called gourds. 

Then there is the popular Halloween variety known as pumpkin. 

All these

They are collectively known as Cucurbita. They are also herbaceous vines. 

Squash is actually a fruit, since it has seeds in the middle of it. However, just like the tomato, people usually refer to this plant as a vegetable. 

And just like the tomato

Squash can be made into different things. You can make savory dishes using squash and it’s also a popular dessert as in squash / pumpkin pie, pudding, and cakes. 

You can also turn it into juice. The pureed form is also a popular soup. 

Or you can just eat it as is. You can steam it or roast it and the squash is already a comfort food. Mashed squash is also popular and is often a recommended first solid food for babies. 

Very healthy, too

There are so many vitamins and minerals present in squash. It has vitamin C and beta carotene, which are great for the eyes. Beta carotene is already good for the skin. 

Squash also contains B6, which would lower your risk of depression. Plus, it’s high in fiber, which would be fantastic for digestion. 

Here are some of the vitamins and minerals you get from squash:

  • Calcium
  • Iron
  • Magnesium
  • Vitamin A
  • Vitamin B6

Moving on

There are two main varieties of squash: winter squash and summer squash. The latter is usually harvested before it has fully matured.

On the other hand, winter squash has a rougher exterior and spends more time on the vine. That rigid exterior allows the squash to be stored for months. 

Here are some of the more popular cultivars of squash:

  • Acorn
  • Butternut
  • Cocozzelle
  • Crookneck
  • Kabocha
  • Pumpkin
  • Scallop
  • Spaghetti
  • Straightneck

  • Zucchini (also known as courgette)

Tips for Growing Squash

Squash is fairly easy to grow, which is also why it is among the most popular fruit/vegetable grown in the garden. 

Of course, people also grow it for its produce and its taste. 

As mentioned

Squash is really versatile. You can make juice out of it or cook soup. It can also be used in various savory dishes as well as desserts. 

Even the seeds of most winter squash varieties can be eaten. The same could be said about the flowers. 

Also, pumpkins are popular decorations during Halloween. 

What squash needs:

If you want to grow healthy and delicious squash, you have to ensure that the right circumstances are applied. 

Here are important requirements for growing squash:

  1. Squash needs full sun. 
  2. It requires sufficient moisture. 
  3. It also needs fertile soil. 


The first thing you need to do is to fertilize your soil. You can use compost in order to introduce moisture. 

Then of course, you need to add fertilizer. The area where you wish to plant the squash should be rich in organic matter. 

This means

You have to mix compost and decomposed manure into the soil. 

This process will also ensure that the soil will drain well. 

Sowing seeds

Since squash fruits are fairly large, they should be planted on the ground. However, you can start indoors. 

You could plant seeds in small containers and then transplant them later. 

But they could also be sown directly into the ground. 

Important tip

You should sow the seeds only when frost has ended. Remember, squash seeds need full sun. This actually means that they need warmth in order to grow well. 

So, it would be better to wait until the soil is a bit warm before you start planting. 

This is why

Some people prefer to start growing squash indoors. This way, they could start planting during winter and they could be kept warm by a heating mat. 

By the time the danger of frost has passed, you already have seedlings that you could transplant into your garden. 


Squash plants prefer to be planted on hills. Not literal hills, mind you. You just need to create mounds of soil that would resemble a hill. 

You could start sowing four to five seeds for every hill.


When the seedlings have developed, you can concentrate on just growing the two healthiest ones. 

This means that you have to remove the weaker seedlings.

Best Fertilizer for Squash

Squash thrives in fertile soil–I think I’ve already mentioned that a couple of times. 

Aside from the fertile soil, you also need to put just a pinch of 10-10-10 fertilizer around the area. 

Moving forward

When you already see the plants growing up, you should then add another dose of fertilizer. This time, you want to sprinkle the fertilizer around the base of the squash. 

The purpose of this is to ensure that your plants will have sufficient amounts of nutrients while they are growing. 


This would also spur growth. It means that your squash will grow fast and healthy to boot. 

Now, it’s important to note that while the squash needs a lot of fertilizer, it doesn’t need to be overfertilized. 

Here’s what you should do

Read the packet of the fertilizer to know how much is appropriate for your plant. 

Don’t forget to wear gloves when you put the fertilizer. A mask and a pair of goggles would be good too, to ensure safety.
