cleaning gravel

I have a pretty basic question. I have a fairly heavily planted
30 gallon tank which contains a couple of juvenile discus and
some tetras. I perform weekly water changes with a gravel vacuum to
help remove feces. However vacuuming the gravel is quite difficult
with all the plants in the tank. How should I go about cleaning
a planted tank without disturbing my plants?
