another tip ; what do your neighbors grow ?
or more importantly , have tried to grow?
in my garden in N.E. :
I was very successful in improving the soil.
we have a lots of leaves , and I had a large dog , x 2 . over two dog
life times. then I had no more dogs
and then plenty of WoodChucks.
what do iguanas like for snacks ?
im not making this up.
might be wise to grow something else.
there are varieties of plastic netting , that's not
obtrusive. find some of that that the iguanas dont like.
good luck ! what a fine project !
