Splitting bark usually occurs in the winter or spring and may be caused by sunscald or fluctuating temperatures (frosts). Generally, trees will heal over splits in the outer layer of bark in the next season, but you can keep it free from insects and disease in the meantime by using a tree wrap. Wrap the tree in October or November and leave the wrap on for the duration of winter. Don’t use paints or sprays.
