(Best months for growing Squash in New Zealand - cool/mountain regions)

S = Plant undercover in seed trays T = Plant out (transplant) seedlings

  • 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.

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.

Hi, The unpollinated will fall off when small. Maybe increase your flower plants around them to encourage bees or do a little pollinating yourself with a cotton bud. Hope this helps

How do you know when to harvest patty pan squash? I have lots of small squash, some vibrant yellow, and other still pale. Some small ones are starting to just fall off and flowers on others are dying. Help please! It looked like this was going to be a bumper crop!!

Most squash are picked when they are small. Look up the internet and have a look. If you like small ones about 40mm and up to 50-60mm for larger. If they are not pollinated they will just shrivel up and die. Read up about pollination.

Hi, I planted Baby squash last season and they all produced beautiful flowers which then dropped off and no fruit was ever produced. I still have 1 plant growing profusely but it is also dropping its flowers and not producing fruit. I have a raised garden bed which consists of Culterra's professional potting soil mixed with last years winter leaves to which I add lawn cuttings from time to time. The raised bed drains well but faces west with full sun from 10h00 till 17h00. To protect the veggies from the hot afternoon sun I have shade netting covering the raised bed. All my various other veggies and herbs have done extremely well. I tend to water every 3rd day or so when no rain is about. I reside in Pretoria. I am also careful with which veggies I plant together. I also follow the principle of planting Marigolds and Basil in with the veggies. I keep peas, beans and cucumbers well away from onions. I grow potatoes but again well away from the raised bed. Any idea what is up with the baby squash? Your assistance will be appreciated.

Probably not being pollinated. Do it by hand. e g just take one of the "male" flowers (the ones on stalks - and a single stem inside the flower), peel the petals off the male flower to make it easier to get into the "female" flowers and rub the pollen onto the "female" flowers (the ones with the fruit under them - and the curled shaped stamens).
