  • Space plants: 24 - 31 inches apart
  • Harvest in 7-8 weeks.
  • Compatible with (can grow beside): Sweet corn

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.

when should you cut yellow ruffle squash from the plant? We were told to cut them young and green and allow to yellow, but they have not yellowed as yet.

I also would like to know when to harvest squash as this is the first time I've grown it. Do you harvest it the moment the flower dies off the end inlike comment before mine are yellow on plant

There are a number of different types of squash ranging in mature colour from pale green to bright yellow. Pick when you feel your squash has stopped growing rapidly. Once the flower is pollinated you will see 2 weeks or so of rapid growth, after which it slows down somewhat. Experience of your own plant will tell you when is the best time to pick them, too big and they get 'floury' and too small and they are not ripe enough. Learn from your own plant, and let them grow.

I am growing button squash. I have no idea when to pick them, they are only quite small but when the flower dies off, if i dont pick them they die. The only thing is i picked some the other day but they were still a little prickerly? The plants leaves also have some kind of mould would this be the reason why i only have very small squash, before it dies??

If the squash die off after the flower closes/dies - this means the flower was not fertilised with pollen from a male flower. I would suggest you carefull pick a male flower (has a single, pointed centre) ensuring you don't shake it so much the pollen drops off, break off the petals surrounding it, & smear it in the crinkly looking centre of the female flowers. Plants can have male & female flowers on them. Re the mould - usually if badly effected the best thing is to pull it out & dispose of in bin. Maybe cutting some leaves off will help it to dry out & stop it spreading due to overcrowding. I have removed lots of leaves on my plants, so they put their efforts into growing the fruits rather than lots of big leaves.

Lyndall, your squash might not be getting properly pollinated. You could try pollination using a small paint brush or similar. A spray of dilute milk can help with the mildew on leaves.

We are growing button squash and eggplant for the first time. When growing squash do you need to pinch off the first few buds to encourage fruiting? Any other tips appreciated.

Hi All, Very new at all of this! Planted squash seeds and they need to be replanted into the vegie patch now & wondering if anyone can tell me how far apart to plant them etc? Full sun? Anly help wld be appreciated :)

Hi Steph, they need full sun, rich soil (dig in chicken pellets or other compost) and lots of space. I've got a couple of plants at the moment that were planted from seed around 10 weeks ago and the plants are around 5ft across. Less rich soils will probably produce a smaller plant. Keep them well watered and liquid fertilise at least once a week and you should have loads to go round! Pick when the fruit are around 5cm across.

My wife is Asian and she says it is ok to eat the plant itself. I know you can eat the flowers but I'm not so sure about the plant. Is it toxic or safe to eat?
