Happens quite a bit here. The wind will blow the plant over, so that is the direction it grows in mainly.

from sa, may i suggest earwigs could be your problem, we followed advice from a friend and put a small amount of olive oil in a clean tuna tin set in the place your zuccs are not to close though, also to check your garden at night when all these nasties come out, good luck.

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?

Hello Sir, I was just reading through the comments further on, and it occured to me that you may have some micro-climates at your new property making things alot cooler/dryer/warmer- outdoor thermometer reads in the area for the day will tell you, and most likely the nutrient balance/microorganisms population is a lot different than your old place...I read somewhere that some squash or pumpkin can change their flowering habits due to a combination of level of nutrients/metals available and plant hormones in the soil, returning to male and female on seperate plants, maybe test the soil for nutrient levels and contaminants if you havent done so already. Is the seed your own or bought? If its not your own seed, you could take it up with the supplier, keep detailed records of these kind of issues and welcome questions about oddities etc, sometimes they purposely breed plants as F1 hybrids so you have to buy more seed to make collecting it not worthwhile
