Q Why do Japanese maple (Acer palmatum) leaves sometimes frazzle?
A Leaves turning brown at the edges, curling, shrivelling and sometimes dying is a common problem with Japanese maples, especially those with feathery, paler or variegated leaves. It can be caused by frost, cold, drying winds, dry or wet soil and sun.

Q How can I avoid Japanese maple leaves frazzling?
A There are a number of things you can do. Keep Japanese-maple plants moist but not wet, especially when grown in pots or newly planted. Place in dappled shade and protect from cold winds. If late frost is predicted after the new leaves have emerged, cover the tree with fleece or move a pot-grown tree to shelter until the risk of frost has passed.
