Gardening in Volcano

[nanasohana]

Since not too many Volcano gardeners are responding, I will give you my opinions on what you should try to grow, staying with cool season crops:
cabbages(which includes broccoli, cauliflower)
lettuces
potatoes
turnips
carrots
onion...at least green
spinach and other greens
peas
celery
strawberries may do well

Now you may have to be very watchful of insects on these crops and turn to soap sprays, row covers or growing in a shadecloth structure if to much insect damage. You will also need good drainage.
I am not sure on tree crops.
