1. How can I transform this sand into soil? I don't think I can convince the owners to finance a keyline layout or other such drastic measures, so I am somewhat restricted and realize it will take a long time, but in monetarily reasonable ways what can I use for cover crops besides sunn hemp (I've heard good things about castor beans and a few others), green manure crops, and local sources of soil building material?
4. Suggestions of pests I should prepare for from the months of September through late May, and if you know of any ways to battle them that aren't reliant on purchasing organic pesticides I would be much obliged. I'm definitely going to be growing hedges, beneficial flower/herb borders, and polycultures throughout the beds to try and limit space for weeds and the temptation of insects. I know a lot of the basics but am looking for locally trusted and successful plant varieties or seed distributors.
5. Is citrus wood okay for hugelkultur beds? I used some to plant veggies in and it did well but I don't know what the long term effects would be and have had trouble finding information.
6. I'm also helping manage a citrus grove-- any advice for plants I should use in a citrus grove to benefit trees? I know of the usual permaculture goodies but looking for more input from locals. Also interested in vegetable varieties that would be well suited for growing between trees, which I have been experimenting with.
7. What is a good mulch or other way to help preserve moisture that works on a farm scale?
