Squash is commonly planted alongside corn and beans, known as the "three sisters," to confuse the adult vine borer.
  • Preparation Ideas: Preheat oven to 400 F. Peel squash. Cut squash in half and remove seeds. Cut into 1" pieces and place in single layer on baking sheet. Toss squash pieces with olive oil and season with salt and pepper. Bake in oven for 25 to 30 minutes until squash is lightly browned and fork tender.
Instructions Chevron Down Chevron Forward
    Growing Instructions:

    Squash seeds can be sown directly in the garden when the soil is warm and all danger of frost is past and the soil has warmed. Soil temperature (not air temperature) should be between 15°- 21°C (60°- 70°F). Plant 2-3 seeds in mounds 1.5-1.8 m (5-6') apart. Press seeds into the soil to ensure good contact and cover with 2.5 cm (1") of soil. After planting, water the seeds with a gentle mist or shower. It is critical to keep the soil consistently moist, but not soggy during germination. When your seedlings reach a height of a few centimetres (inches) and have developed 2 or 3 pairs of leaves, it is important to thin them out, according to the plant spacing indicated below. Do not allow the soil to become dry, as young plants have underdeveloped roots and can quickly dehydrate, particularly in windy conditions.

    For an earlier crop, squash seeds can be started indoors 3 to 4 weeks before the last frost in your area. Follow the seed depth and spacing guidelines indicated below. Once all danger of frost has passed, seedlings should be hardened off before planting in their growing location. Seedlings should be transplanted according to the plant and row spacing directions below. Regularly monitor your plants and ensure that the soil remains moist, but not soggy while they establish themselves in their new environment.

  • Planting Depth: 2.5 cm (1")
  • Plant Spacing: 3 per hill
  • Row Spacing: 1.5-1.8 m (5-6')

  • Instructions for Nutrient Care: Feed plants SUPERthrive once per week. Mix 1.2 ml (1/4 tsp) per 4L (1 gallon) of water in a watering can and apply solution to the base of the plants.
Suggestions Chevron Down Chevron Forward
Growing Suggestions:
  • Use a row cover during the first few weeks of seedling growth to protect plants from insect pests. Remove covers before flowering to allow pollination by insects.
  • Try to water plants at the base of the plant rather than overhead unless it's a sunny day. Dampness on foliage and fruit invites rot and disease.
  • Squash have shallow root systems and care should be taken when cultivating and weeding near the plants.
  • Squash plants have distinct male and female flowers. The male flowers appear first on long, thin stalks, followed by the female flowers with an immature fruit at the bottom. For the female flowers to produce fruit, they require pollen from the male flowers to be transferred to them by bees.
  • Poor pollination can result in squash flowers that do not bear fruit, or that bear small fruit. Consider growing bright-colored flowers nearby to attract pollinators.
  • If you're growing squash with a bush or vining habit, it's important to check for overcrowding and thin out a few lateral (non-main) stems or lower leaves (especially those touching the ground) to ensure better air circulation. This can help prevent the spread of disease like powdery mildew, reduce hiding spots for insect pests and make it easier for pollinators to find the flowers. Keep in mind that overcrowding can also cause weakened growth, so it's important to leave enough leaves for the plant to produce food for itself. Don't prune more than 1/3 of the plant.
  • An idicator that squash is ready to harvest is when th stem turns from green to brown woody stripes where it joins the fruit. When harvesting, cut the squash from the vines using a sharp knife or pruners. Avoid twisting or pulling fruits from the vines. Leave about 5-7 (2-3") of stem on each squash.
