I noticed a big old Valencia orange tree today that I thought was dead was beginning to bud out some leaves. Won't have any oranges this year, but maybe next. I planted two more Satsumas close to the house on the south side hoping I can either keep them misted in freezing temps or I can build some plastic sheeting panels I can use to protect them. They are loaded with little Satsumas right now. If the grapefruit sprouts from the stump it will probably be the root stock and not any good.
