I'm trying and with some success. I put planter boxes all along my two decks and filled them with black dirt. I use rain water. The first three herbs I planted did very well; basil, parsley and turnip greens. I have been using all of these and giving away extra. Two weeks ago I planted cilantro, chives, rosemary, acorn squash, jalapeños and long red peppers. The cilantro germinated in 3 days and the other in 5 to 6 days.
In a section I call the farm (cleared open area) The cantaloupe seeds sprouted well. The iguanas got 8 hills and I have 4 left. They are flowering nicely and have set a couple of fruits. The watermelon sprouted in the planters but was transplanted to the farm and did not survive. I was told that mint is a deterrent for iguanas and did find a few scraggly plants. These few have spread nicely.
I purchased a great horned owl solar powered life sized statue, the eyes are scary as $#!+, and the thing makes a clicking sound as the head rotates. This I had mounted on a stump in the middle of the farm field. I want my caretaker to make a few clacking whirligigs to add to this area to keep the birds out.
These nightly rains and sunny days are doing wonders. One of my friends (who knows everything - really) insists that the days are not long enough to ripen foods. This does not make sense to me as it grows under the same sun on the mainland
My attitude: What have I got to loose? $1 US on each packet of seeds and the joy of watching it sprout is enough to delight this simple soul.
NOTE: Potential ex-pats - it really doesn't matter what you do when you come here - just do something to amuse yourself and keep living not sitting on a bar stool dying.
