Ask John

Q: Hi John,

I purchased a coral bark Japanese maple from you about 6 weeks ago. I planted it as recommended. The leaves are turning brown which started about 2-3 weeks ago. What do you think is causing this?

A: Hi Deb,
 

Great question and an easy solution. This process that you are experiencing is a botanical term called transpiration: Transpiration is essentially evaporation of water from plant leaves. That means there is not enough water in the soil or root system to sustain the leaves. We recommend buying a soaker hose to lay around the base or a tree watering bag. It needs a deep watering twice a week. Don’t stand over the tree and water it since it mostly stays on the surface. Prune back any dead tips.

You should see a happier tree over the next few weeks by following these tips.
