Splits in peach tree bark have opened within the last few days. I'm certain of the timing, because I've been spraying trees, and had carefully gone over the bark of these trees earlier this week. There was one small split on one tree at that time. Now two trees have severe damage. I see no sign of discolored wood, sap/resin, or other exudate in or near the splits. The only possible cause I'm familiar with is freeze damage over the winter. Would such splits open now (early spring)? If freezing is the cause, how should I manage the damaged trees? One source suggests carefully cutting around the wound with a sharp, sterilized knife to encourage healing. These trees are in a home orchard (about a half-dozen each of apple and peach trees). So if this is disease damage, should I consider removing the affected trees to prevent disease spread to the rest of the orchard? Thanks for your advice!
