apart from maples, i am now a fan of orchids - i usually go to that section to read on threads in caring for orchids. i was wondering, is there guidline to follow in taking care of maples such as Sangokaku? last summer, i noticed the leaves at the tip turn brown from top branches... is that related to too much sunlight? not enough watering? or over fertiliser? i hope someone has the patience to write "THE BASICS of caring for MAPLES"
