I had a landscaping company plant two Cockspur Thornless Hawthorns that seem to be struggling. First of all the trunk itself is very 'bark-y' with the bark curling away from the trunk. Is that normal? Also, the trees keep sprouting at the bottom. I trim them about every 2-3 months. I've had them almost two years. They do leaf but one has some leaves turning reddish already. I was told to water them them twice week and these trees are exposed to full sun for about 6 hours day. Also I feel thorns on the clippings at the base of the tree - so is this really a 'thornless' cockspur? Help!!
