(Best months for growing Squash in USA - Zone 5a regions)

  • S = Plant undercover in seed trays
  • T = Plant out (transplant) seedlings
  • 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 70°F and 95°F. (Show °C/cm)
  • Space plants: 24 - 31 inches 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 5gm/teasp Bicarbonate of Soda in 600ml/pint of water will help slow powdery mildew when it appears.

Culinary hints - cooking and eating Squash

Use whole or sliced. Steam or fry.

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.

You are talking about butternut pumpkins aren't you. Best to ask in the pumpkin section not the squash. Go to pumpkin enter your climate zone and then check the planting guide.

Butternuts are considered a squash.

I have read article on planting the 3 companion plants together..have planted sweet corn & French runner beans & looking for a suggestion for something climbing for trellis behind Don't particularly like squash..

My suggestion is plant them in separate areas, all three that is. I have just harvested a block of corn, there is no way I could have planted climbing beans amongst them. You would have to thin out the corn planting therefore effecting the pollination ability of the corn. Do you want small thin cobs of corn. I feel you would end up with a poor crop of each vegetable. Corn needs fertilising, beans don't need much, conflict.

I am growing squash at the moment, but flowers grow then bud ( squash) grow then fall off when really tiny. First year this has happened. Grew plenty last year. Is it the extra heat we are having here in QLD? Is it because they are now growing on trellis? Last year just left on the garden bed similar to pumpkin.
