|I have a Waterfall Japanese Maple (my nursery bought it from you). I planted it in a copper container. Now the leaves are getting dry, burt and brown, particularly on their edges. The plant seems healthy otherwise, but its leaves do not have the vivid green color that they used to. What can I do?|
|A common maple problem is leaf scorch. This is usually a result of hot afternoon sunshine, but it can also be caused by fertilizer burn (salts can especially build up in containerized plants). I'd move the maple to a site that gets morning sun but only filtered afternoon sun (or bright afternoon shade). When you fertilize, use a water soluable fertilizer (such as Peter's or Miracle-Gro), and to keep salts from building up in the container, leach the soil every few months by immersing the container in a larger container of water for 15-20 minutes.
Best wishes with your maple.
