watering

Japanese white pines require weekly watering, about 1 to 2 inches per week. Make sure to water the roots so moisture can reach them. Be sure that the soil remains evenly moist, but not overly soggy. It is best to water in the morning and avoid getting the foliage wet, as it can lead to fungal diseases. During the warmer months, check the soil frequently to ensure it is not drying out and that your Japanese white pine is not being over-watered.

sunlight

Japanese white pine (Pinus parviflora (Glauca Group)) prefers full sun, but can tolerate partial shade. It needs 6 to 8 hours of direct sunlight each day to thrive. These plants prefer full sun exposure in the morning and afternoon, but can tolerate some shade in the middle of the day. While too little sunlight can lead to unhealthy growth, too much sunlight can cause the foliage to scorch. Japanese white pines should be given indirect sunlight during the hottest part of the day, especially in areas with intense sun exposure.

pruning

Japanese white pine (Pinus parviflora (Glauca Group)) needs to be pruned in early spring as soon as new growth begins. Prune back new shoots that are longer than 6 inches and any shoots that grow inward toward the center of the plant. Remove excess candles from the main apex of the tree to maintain a strong central leader. The goal is to keep the overall silhouette compact and well balanced. If desired, a few outer branches can be pruned to open up the canopy and allow light to reach the inner foliage.
