« why has my acer not got many leaves on the branches this year
Have you got it planted somewhere where early morning sun hits it, i.e., an east facing position? This is usually the cause - sun hits frost on buds before its had a chance to melt, causing the buds to die and drop off. Other possibility is drought.
