How to Grow Summer Squash

Summer squash tends to be a prolific grower that doesn’t need a lot of extra attention to thrive. In fact, favorites like zucchini will produce plenty of fruit for your table even if you forget about it, and just let it grow wild in the garden.

Avoid growing your summer squash varieties too close to each other or growing them with melons, cucumbers, or winter squash. This is important if you plan on saving seeds for later use as not only can the flavor of these change with cross-pollination the end result of saved seeds can be a bit of a wild card.

Before planting your summer squash you should add plenty of fresh compost to help give your plants the nutrition they need to thrive. Make sure your soil is well-draining, and maintains moisture and nutrition well. Add organic matter to clay or sandy soils.

While your summer squash can thrive when directly sown into the garden you can also make the most of your gardening season by starting your summer squash plants indoors 4 to 6 weeks before the last frost. For the best results, you want to keep your seedlings above 70 degrees to assist with germination and early growth.

Start your summer squash with 2 seeds per seed starting container or hole in your garden. After true leaves have formed thin to only one plant each ensure that your summer squash has plenty of room to grow.

Plant your summer squash at least 2 feet apart to give the plants plenty of room to spread out. Despite being more of a bush plant than a vine plant most summer squash varieties do grow quite large.

Summer squash plants are very heavy feeders. In addition to adding in the compost when you plant your squash, you want to fertilize often to help ensure that the soil has enough nutrition for your plants to grow and thrive.

If your summer squash is not receiving enough nutrition in your garden you will find that you may have issues with blossom end rot. Testing your soil acidity can help you determine what needs to be done to balance your soil if you see blossom end rot appear.

Mulch your summer squash and use the deep watering method if you do not get a lot of rain to make sure these heavy feeders have what they need to thrive. Keeping your squash well-watered is essential to helping produce larger fruits that can provide your family with more food.

Dealing with Pests and Your Summer Squash

Summer squash plants tend to have issues with squash bugs and squash vine borers. While your plants are young you can use floating row covers to help prevent squash bug eggs from being laid.

Harvesting and Using Summer Squash
