Hello all, greetings from Hawaii. I don't have my profile set up yet but I'm at about 800ft and 180inches rain.
I have about 6-12 inches of soil so I planned on making flat circular mounds and surrounding it in vetover grass.
My question is: should I use say 20%
compost 80% fill dirt, or just amend the planting hole? If I use more than 20% will the compost break down into nothing and make the mound smaller?
Mahalo.
