My pears on the tree are big yellowish with brownish dots and hard. When should i pick them? Will a frost harm them? Thanks.
Sounds like you have some nice pears. The brownish dots are nothing to worry about…they can be avoided by using a fruit tree spray every 2 weeks during the growing season but the spots are harmless and common on organically grown pears. I go ahead an harvest them. A light frost probably won’t harm them but a freeze will. They will finish ripening just fine inside the house.
