I live in Hawaii and we can plant almost everything yr around. We can't grow tomatoes (except cherry tomatoes), melons, most peppers, anything with a soft skin. Medflys get them and rots them. In a green house people grow tomatoes, peppers as such. Garlic likes a cold season to grow so I put my garlic i'm going to plant in the refrigerator for 3 months which tricks them that is their cold season and I get some nice looking garlic. I do use the cuban variety though. I have worm bins for worm casting and mycorrhizal fungi when transplanting for a healthier, bigger plants and for the most part disease restraint. Love mycorrhizal.
