I’d appreciate advice on how to over-winter my Endless Summer hydrangeas in urns. For instance, should I move them into the garage (unheated), then when, or give them a special fertilizer? I’m hoping they will re-bloom next year and remain healthy planter plants for several years. I’m in Zone 7b (northern NJ).


Your Endless Summer Hydrangeas in the urns are so elegant! It will be best to bring the plants into a garage or basement for the winter months. Our container gardening guide has information including winter watering. If the urns can’t be moved, you could remove the hydrangeas and place them in containers to bring in for protection. Hold off on fertilizing until spring. You don’t want to encourage new growth going into winter.
