Welcome to the ultimate guide on how to grow delicious and nutritious squash right in your own backyard in the UK. Whether you have a sprawling garden or limited space, this step-by-step guide will walk you through the entire process of growing squash, from sowing the seeds to harvesting and storing the bountiful fruits.

Sowing and Planting Squash

Before you begin, choose a sunny spot in your garden or allotment for your squash plants. Squash loves warmth and requires at least 6-8 hours of direct sunlight daily. Start by preparing the soil, ensuring it is well-drained and rich in organic matter.

Soil Type

Squash plants thrive in fertile soil with a pH level between 6 and 7. If your soil is heavy clay, add organic matter such as well-rotted compost or aged manure to improve drainage and fertility. Sandy soil can benefit from the addition of organic matter to improve water retention.

How to Grow Squash from Seed

Start your squash journey by sowing the seeds indoors in early spring, around 4-6 weeks before the last frost date. Fill seed trays or small pots with seed compost and plant the seeds about an inch deep. Keep the soil moist and warm, and within a week or two, you will see the seedlings emerge.

How to Plant Out Squash

Once the danger of frost has passed and the seedlings have developed a few true leaves, it’s time to transplant them into the garden. Choose a location with enough space for the sprawling vines to grow, or consider vertical growing techniques for limited space. Dig a hole, place the seedling carefully, and cover the roots with soil. Water thoroughly.

How to Harvest Squash

As your squash plants grow, you’ll notice beautiful yellow flowers that eventually develop into fruits. Harvest time varies depending on the variety, but most squash is ready to be picked when the skin is firm and the fruit has reached its mature size. Use a sharp knife or secateurs to cut the fruit from the vine, leaving a small stem attached.

How to Store Squash

Proper storage is essential to enjoy your homegrown squash throughout the year. Store them in a cool, dry place with good air circulation, such as a pantry or cellar. Avoid storing them directly on the floor to prevent rot. Check your squash regularly and use any that show signs of spoilage promptly.

Problems with Growing Squash: Common Pests and Diseases

While growing squash can be rewarding, it’s important to be aware of potential pests and diseases. Common squash pests include aphids, squash bugs, and vine borers. To prevent these pests, consider using row covers and practicing crop rotation. Powdery mildew and blossom end rot are common diseases that can affect squash plants. Proper watering and good air circulation can help prevent these issues.

Where to Buy Squash

You can find squash seeds and young plants at local garden centers, nurseries, or online retailers. Look for reputable suppliers that offer a wide range of squash varieties suited for the UK climate. Consider heirloom varieties for unique flavors and shapes.

Best Squash Varieties to Grow and Why

When choosing squash varieties, consider your taste preferences and growing conditions. Butternut, acorn, and spaghetti squash are popular choices for their versatility in cooking. Pattypan and yellow crookneck squash are known for their unique shapes and flavors. Experiment with different varieties to find your favorites!

What Tools Will I Need to Grow Squash?

Fortunately, growing squash doesn’t require a vast array of tools. Basic gardening tools such as a spade, garden fork, and watering can are essential. Additionally, a trellis or stakes may be necessary for vertical growing methods. A sharp knife or secateurs will come in handy during harvest time.


Growing squash in the UK is a rewarding experience that allows you to enjoy the flavors of summer all year round. With the right soil, proper care, and a little patience, you’ll be harvesting your own delicious squash in no time. So, roll up your sleeves, grab your gardening tools, and get ready to embark on your squash-growing adventure!
