Outdoor: Be ready to put your trees into winter protection as soon as the weather dictates. A night temperature of 25°F is a good reference point for when the trees need protection. Remove the remaining foliage on deciduous trees and any weeds or debris on the soil before placing the trees into winter protection. Spraying with a general fungicide can be beneficial. Keep your trees well watered. The trees will use less water in the current cooler temperatures. Fertilization may be stopped at this point. Do not repot except in the case of an emergency. Wiring may be done and is often easier on deciduous trees after the leaves have fallen.
Indoor: Provide maximum amounts of light during the fall and winter seasons. The use of artificial light may be needed. Fertilize trees growing under artificial light. Water as needed for your indoor conditions (light, temperature, humidity)
