Could be solved with a highly directional antenna that rejects signals
not in its direction.  You'd probably need amplification as well. The
wider the separation of the multi-paths, the better. If the
configuration is such that you're getting a slightly delayed signal
from the same direction then you're probably out of luck.

Is it possible that the vegetation is lensing the radio frequency,
giving you a stronger signal?

More likely, in winter the vegetation is no longer blocking the stray
multi-path signals, giving you a better signal in summer.
