Are there any Japanese Maple trees that like full sun in zone 6?

Japanese Maples prefer dappled shade. I do not know of a Japanese Maple cultivar that likes full sun.

You can get an acer rubrum which is a red maple and will tolerate full sun--even it will get burnt leaves in the heat of summer. The maple you want has to have some protection from the elements and shade.

you're drowning the little timber moist isn't meant to be soggy placed them in easy coloration and shrink the water which you're giving them. preserve from west(afternoon) solar. what kind potting soil, what moss? i could advise repotting them into miracle gro potting soil, it has stable fertility and texture stable success
