watering

Eastern White Pines can survive with a moderate watering regime. Watering should be done every 2 weeks during the warm season. During the cooler months, only water once a month. When watering the plant, be sure to give it a thorough drenching, providing a good soaking of several gallons of water until the water drains out at the base of the plant. Do not leave the plant sitting in standing water. This type of pine is prone to fungal root rot caused by overwatering, so be sure to check the soil to determine when it is time to water again.

sunlight

Eastern white pine (Pinus strobus 'Horsford') thrives with at least 6-8 hours of direct sunlight throughout most of the day. For optimal growth, place this evergreen tree in an area that gets plenty of good morning sunlight and some afternoon shade during the hot summer months. The ideal position for this species is in a location that is in full sun in the early morning and afternoon, and part shade during the midday hours.

pruning

Pruning Eastern White Pine (Pinus strobus 'Horsford') should be done twice per year, once in the late winter (February - March) and then again in the early summer (June). The goal of pruning is to improve the overall structure and shape of the tree. During late winter, pruning should be done conservatively, removing only dead, diseased, or damaged branches, as well as any crossing or rubbing branches. In early summer, pruning is focused on shaping and thinning the crown. Thinning allows for more light to penetrate the tree, stimulating stronger and healthy growth. When pruning, approximately 10 to 20% of the branches should be removed. Be certain not to remove more than 30% of the foliage otherwise it may not survive.
