The tree was growing lopsided and had no stakes to hold the weight of this year's fruit. A smaller branch broke and then two days later, the entire tree was down. The trunk cracked and several branches just fell beneath the heavy load of the fruit. The nectarines are not entirely ripe, but I picked as many as I could. Should I prune the downed branches and continue to le the fruit try to ripen, or do I need to just cut it down?
