Answer: I'm not sure where you're located, but if you are in the Eastern U.S., your soil will tend to be acidic, so adding lime is fine. Of course, the best thing to do is a soil test to determine the pH. For vegetables the range is 6.0-7.0. If you are on the low side, add 40 pounds of lime per 1000 square foot of garden. Horse manure is great as a soil conditioner. Be sure to get old, composted horse manure because the fresh stuff has lots of bedding materials (sawdust, hay), which can tie up nitrogen int he soil and casue a deficiency. Anything older than one year is fine. Also, horse manure tends to have lots of weed seeds, so be diligent about weeding.
