Joe Blair will demonstrate apple tree pruning on the grounds at Hildene. Blair will focus on two forms of pruning: corrective pruning for ornamentals and pruning to increase productivity for fruit-bearing trees. The arborist will demonstrate these techniques on the Lincolns’ historic apple trees with time for questions and answers throughout. 1:00 to 3:00 pm. This Hildene horticultural program is free and open to the public. Check in is at the Welcome Center.
