Okay, how's this for basic---I've been vegetable gardening in a very casual way in containers the past few years. My husband finally gave in and said he couldn't stand the look of all my plastic buckets and tubs and built me three great big raised beds to potter around in--each of them 4' x 16' by 24" deep. They sit on some pretty hard granite-based soil typical of So Cal (which is why I used containers before, you could kill yourself chipping away at this bedrock).
So far, the beds are empty---no soil, no nothin' except for the irrigation pipes and a few vaguely puzzled chickens. I can place an order with SoilDirect or something similar for whatever I need to fill up the beds and get started---but what should I start with? My choices appear to be 70/30, 50/50 or 30/70 soil/compost. I have both horses and chickens on my property, so an ongoing supply of compost won't be a problem, but I don't have nearly enough ready to go right now to fill the beds. I'm assuming straight compost isn't the right thing---I previously tried filling some of my containers with straight compost (well-rotted, lovely stuff courtesy of the horses) and while some plants did okay, it seems it was just too much of a good thing for others.
Any and all suggestions would be greatly appreciated! BTW, I'm brand spankin' new to the forum, so if there's an area Basic Answers for Gardening Imbeciles, point me to it---I'm not adverse to topics like "how to recognize a tomato" or "insider tips for turning on the water hose". Thanks!
