How many times should I till and spread horse manure before I plant my garden?
Really, as many times as ya want. There's no such thing as too much horse manure (unless it's still all in the stall- then any amount is too much). :)Buy a soil test kit. It's easy to do and cheap, too. If you need to seriously ammend your soil, it'll tell you what's lacking, and you may need to put in more than horse manureHoof trimmings are good too. And coffee grinds.
