  • S = Plant undercover in seed trays

  • P = Sow seed
  • Grow in seed trays, and plant out in 4-6 weeks. Sow seed at a depth approximately three times the diameter of the seed. Best planted at soil temperatures between 21°C and 35°C. (Show °F/in)
  • Space plants: 60 - 80 cm apart
  • Harvest in 7-8 weeks.
  • Compatible with (can grow beside): Sweet corn
  • Mother Hubbard squash
  • Pattypan squash

Start in individual pots then transfer when all risk of frost is past. For succession, later plantings can be straight into the ground. Fast maturing squash varieties for summer growing. Not suitable to store like pumpkins. Usually grown to pick when young and used without removing rind or seeds.

Zucchini/courgette (see under Z) is also a variety of squash

Protect from frost. Water well. Grow on well mulched, raised area. Shelter from strong winds.

A spray with a 5 gm/teasp Bicarbonate of Soda in 600 ml/pint of water will help slow powdery mildew when it appears.

Culinary hints - cooking and eating Squash

Use whole or sliced. Steam or fry.

Which squash varities can trellis? Some say trellis summer because winter is too heavy. Some say you cant trellis summer squash because its a bush plant and only winter squash will vine/trellis. Please help.

Some varieties of both winter and summer squash trellis while others do not. You just need to pick a small, vining variety. I too have heard that it's not worth trellising any type of summer squash because the vines are not so long that you save much space... so here I am with Pattypan dancing circles around their 8ft bed. Next year they're going on a trellis. For winters, focus more on size; I've seen pictures of Kabocha on a good, strong trellis but not sure which varieties like your cooler climate.

When can I start winter squash--acorn squash, especially?

All squash is planted at the same time. Summer squash will be ready to harvest in the summer months and winter squash will take longer and be ready in the late fall/winter months. This should help with planning out where to plant as well. Happy Gardening!

CAN I PLANT BUTTERNUTS NOW (FEB)? (Gardenate replied : It depends on when cold weather starts in your local area. The plants might not have time to develop before the soil is too cold.)

Spring is the best time to sow all your cucurbit family members.
