I bought this texas scarlet chaenomeles japonica at a big box store last month, since it looked healthy, large, and relatively low priced. It was only after I took it home and started chopping away all the twiggy growth that I noticed my intended trunk has some reverse taper in spots. If it just is a matter of branches having grown wrong, then I'll eventually shorten to below those points and it won't matter. What I'm concerned about is if some insect o r fungus or virus has done these. Are they galls like oak trees get? Will they spread throughout the tree? Will they spread to nearby trees of the same family? Is there a cure I can buy somewhere?
