Pea straw is great as a mulch, don't worry about the peas sprouting they will be putting nitrogen back into the soil plus you can eat the peas, maybe wouldn't be a good look in the front garden. Personally I use the sugar cane mulch as it seems to get the worms moving probably because there a traces of sugar still in there. The absolute best mulch I have used, and the cheapest was dag ends off the sheep, benefit of the **** still on the wool and the wool breaking down itself releases amino acids into the soil another plus is the worms and microbes love it I paid $20 for a bale weight around 200 + kilo.
Dusting the veg with Derris dust a natural insecticide from some sort of bean, got taken off the market once before but now it is back so I am not sure whether it is safe, they advertise it as 'natures way' does kill most bugs and caterpillars.
If your starting with a blank canvas shaunous I would be looking at Aquaculture especially if you have the space, I was thinking of starting from scratch next year but I have to many established fruit trees I would have to take out, plus I have started working again so I will be time poor :unsure:
Will PM you when I find my invoices of where I bought the mesh and poly, the floor I rolled out with shade cloth from eBay heavy duty and cheaper than Bunnings.
