Sounds like the opposite of a good microclimate maker... Shades from the 'high' summer sun, and allows radiational frosts in the winter Unless you're talking about an evergreen one, in which case it would only be half as bad.billdango wrote:It would look even better if the oak [or any other broadleaf trees] are at least fairly mature and the palm and banana trees are growing underneath the lower branches.
The best deciduous tree would be one that is bare in the summer and in leaf in the winter - it would allow the 'high' summer sun and low winter sun, and provide frost protection and greenness when it's needed the most.
