I planted a Rhus typhina in 2009, it was about 1 metre tall and in a 3 litre pot. In january 2010 I noticed after gale force winds that the bark had split on the trunk. White sap was seeping through the split, thought this may be a sealant to protect plant. More bark has split since, the plant is growing and producing foliage and seems healthy enough. Is there some kind of bandage to protect it? Why did it happen and is it a common problem?
