Always check the moisture content of the soil before watering. Fertilization should continue. Check wires for…

Outdoor: All outdoor trees should have been removed from winter protection and placed on their growing benches. The trees should be receiving as much sun as possible. Watering needs will be high, and all trees will need watering at least once a day.
