(Best months for growing Squash in South Africa - Semi-arid regions)

  • 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 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.

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.

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).

my next question is how does one determine the male and female of the flowers?

Male flowers will have a longer, spindly stalk and only produce pollen (the male half of the deal) while female flowers have shorter stems and an undeveloped fruit (the female half of the deal). This fruit will develop into a squash or pumpkin when and if pollinated. Trust this helps.

Hi Guys, I don’t know if this is the right forum for this, but, can some explain to me why a gem squash plant I have has produced so many flowers and yet not one has grown into a squash. I have seen the small squashes grow to about 1cm and then the little stalk starts to dry out and the squash falls off. I have it growing as a vine to keep it off my courtyard floor, is this part of or the problem,
