I had the same problem - I cut off the bottoms of soda bottles, threw away the lids and placed the bottle over the plant, pushing it into the soil enough to stop it from blowing over. I then simply removed the bottle when the plant was looking a little cramped - worked a treat!

An extreme method would be to make a wood frame about 50cm high and cover with 30% shade cloth. OR put stakes in the ground and use shade cloth or bird netting as a fence. I have 2m x 2m x .5m frame with veggie netting on and around it. Only problem the netting disintergated from flapping on the wood frame. I will replace with 30% shade cloth soon. Or make an arch with plastic pipe or chicken netting and cover with shade cloth. Look around the yard for things you could use.

Go on the net and look for a natural spray - usually soapy water mixed with other things. Probably you have some grubs.

It is more about planting it the right time. Grab a packet and give it a go.

What would you suggest around Brisbane in regard to spacing the plant?

Hi, i have big healthy plants buth but the fruit are turning yellow and shrivelling. Ive harvested 6 out of around 20 ive had to throw away. Ived been trying hand pollinating but it seems to make very little difference. Are there any other issues that could be causing this?
