Container Preparation

Squash plants reach about 4-5 feet in width when mature and will need a large container to grow in. The container does not have Susquehanna-SP17871-20-Inch-Large-Outdoor-Square-Planter-Cedar-0to be 4-5 feet wide, but it must be wide and deep enough to support that size plant.  Half of a 55 gallon barrel or an old tire make perfect containers for squash growing. Make 3-5 drainage holes in the container bottom and place a coffee filter over each hole to prevent the potting soil from leaching out during watering.

Squash grows rapidly and needs fertile, loose soil so the roots can seek out soil nutrients to feed the hungry plant. Mix potting soil 50/50 with compost, then add 1 cup of granulated 10-10-10 fertilize. Fill container with soil mix and water thoroughly until water comes out of the bottom drainage holes. Wait 24 hours before planting seeds or plants.

Planting Time

Squash is a warm season vegetable, so wait until air temperature reaches 75 or above for 3 consecutive days before planting. Place 1 plant or 2 seeds in a shallow hole in the center of the prepared container. Cover with potting soil and water in well. Keep soil moist and seeds will germinate in 4-7 days.  Apply a 2 inch layer of organic mulch around plant when it reaches 6 inches tall. Plant seeds at 2 week intervals to extend the harvest time.Seeds-of-Change-06000-Certified-Organic-Seed-Lioness-F1-Squash-0


Squash will do its best when placed in a location that receives full morning sun and partial shade in the afternoon. When the plants are placed in full sun, they will wilt in the hot afternoon sun and vegetable production will slow down.

 After Care

Squash are heavy feeders and need to be fed once a week. Keep soil moist at all times and feed with a water soluble plant food mixed at the recommended rate every week. Harvest squash at any stage of development, but don’t allow them to get over 10 inches or they will become hard and inedible. Squash blooms can be harvested and eaten, but remember each bloom represents a future squash. Pick the bloom and the squash won’t develop.
