Hi Tim,

I don'th think that the amount of organic matter in organically amended garden soil is enough to raise its temperature significantly. High nitrogen organic matter (like fresh horse manure or fresh grass clippings) does heat up due to the life activities of bacteria, and when a compost pile is made using a large enough component of such materials, the whole pile heats up, but we don't want to be planting directly in any organic material that is in the "heating up" stage of decomposition. The French intensive market gardeners around Paris used what they called "hot beds," made by burying fresh horse manure deeply in a bed, then adding soil, then planting on top. That warmed the soil. However, they knew not to plant directly in the manure, since the bacteria that do this would be likely to decompose the seedlings as well.

With organic methids the soil tempurature should be a little warmer as there is more organic matter which stimulates microbes which produce heat.
Kind Regards

Hi: I just moved into a house near City College with an old and overgrown garden filled with ornamental shrubs and trees and a number of fruit trees. Can you recommend a source for identifying the fruit trees and flowers? I'm going to get Golden Gate Gardening as well, but I'm a real novice when it comes to gardens. I only know how to weed and turn on a hose and I'm eager to learn how to handle my lovely garden. No one has lived in the house for 7 years, but the previous owner was a rose and fruit fan and obviously took great care with her backyard. Thanks.
