Growing squash in a container is a practical solution for growers with limited space, as squash plants occupy much room in vegetable gardens. You can easily and enjoyably cultivate squash on your deck, patio, or indoors. This article provides a step-by-step guide on how to grow squash in a container.
How to plant squash in a pot
Some common varieties, such as pattypan, yellow crookneck squash, and zucchini, are among the most commonly grown varieties of summer squash. Summer squash plants grow rapidly and typically start producing fruit within two months of planting seeds. After the flowers bloom, it takes approximately four to eight days before they are ready to be picked.
How to plant squash in a pot
- Select your planting pots.
Choosing an appropriate pot size is important for growing squash plants in containers. Squash plants have a shallow root system that doesn't require overly large containers. It would be best to use a pot of at least 12 inches deep of soil per squash plant.
- Create drainage holes in the planting pots.
To prevent rot and fungal diseases, it's essential to use containers with drainage holes at the bottom. Ensure that any container you use for growing squash has drainage holes to allow excess water to escape.
- Fill the pots with soil.
Fill your planting pots with soil rich with nutrients, and add little water to keep the soil moist.
- Insert the squash seeds
Use a stick to create a hole channel and gently insert a seed per pot. Cover with soil after planting the squash seed.
- Water after planting.
After planting the squash seeds in the pot, you need to water them to keep them moist. A dry environment will not facilitate proper germination.
- Arrange the pots under a shade.
Arranging the newly planted squash seed in pots under shade is highly recommended to prevent direct sunlight.

How to plant a squash seed
When the weather is consistently warmer than 60°F in late spring, you can directly sow squash seeds in your outdoor pots. It’s important to monitor the nighttime temperatures and bring the pots inside if they drop below 40°F to protect the young plants.
Fill seedling trays or peat pots with a rich seed-starting potting mix and lightly saturate the soil to start your squash seeds. This will give your seeds the necessary nutrients and moisture to germinate and grow into healthy seedlings.
How deep to plant squash
To ensure the successful germination of your squash seeds, plant them one inch deep in the soil and then loosely cover them. After planting, place a humidity dome, plastic wrap, or mulch over the tray to retain moisture and create a warm environment to encourage germination.
Squash seeds typically germinate between five and ten days, with an ideal soil temperature range of 80-90°F. If the soil temperature falls below 60°F, the seeds won’t germinate. It’s important to maintain the appropriate temperature to ensure the successful germination of your squash seeds.
How to transplant squash plants
Before transplanting seedlings, it’s important to acclimate them to outdoor conditions through hardening-off. This process helps prevent stress and shock to the seedlings. Hardening-off involves gradually decreasing water and artificial heat while slowly exposing the seedlings to normal outdoor conditions.
After thinning your squash seedlings, begin hardening off by decreasing the water and turning off the propagation mat. To encourage sturdy stem growth, ensure the seedlings receive ample bright light and keep them near a sunny window to prevent legginess.
Transplant both winter and summer squash into a site with full sun and very fertile, fast-draining soil after the last frost in spring.
Before planting, water the seedlings to ensure they are hydrated. To plant the seedlings, dig holes twice the width of their pots, spaced 1 to 2 feet apart, for optimal growing conditions.
To plant the squash seedlings, gently rip the bottom of the compostable pots and tear up the sides without removing the pot entirely. Settle the seedling into the hole, ensuring the base of the stem is level with the surrounding soil for optimal growth.
After settling the squash seedlings into the holes, fill in around them with the tilled, amended soil and gently firm the soil to collapse any air pockets.
Water the seedlings thoroughly to give them the hydration they need for healthy growth.
So, this guideline on “how to plant squash plant should help you successfully plant your squash from the nursery to the point of transplanting. Below are some frequently asked questions about planting squash plants in pots.
