Hi Nikv, thanks so much for the message and great info, you are always a wealth of knowledge. Thanks for the tip on the bottles, we've used some inverted bottles in the garden around the fruit trees, but will definitely do more.
The shade cloth will be an absolute must, there is a local supplier here but they seem to only sell 80 and 90%, will look around some more before summer gets here.

Black soldier flies oh wow, that's really interesting. I've read up on them before and they've actually started farming them in parts of SA. I always thought that they were much smaller than these gigantic goggas that like our compost. Good to know and I'm happy to welcome whatever bugs help with the decomposition.

Appreciate your wisdom and help, have a lovely night :)
