watering
The Swiss stone pine should be watered deeply once a week during the growing season, and every 2 weeks during the winter. In particularly hot weather or very dry periods, the plant may need to be watered more frequently. Saturate the soil until it is wet to a depth of 8-12 inches and allow time for the soil to dry out before watering again. Make sure not to overwater, as this can lead to root rot, fungus, or other issues.
sunlight
Swiss stone pine (Pinus cembra 'Glauca') generally prefers an exposure of full sun or partial shade, with roots ideally in partial shade. For best results, the Swiss stone pine should receive 8 to 10 hours of direct sunlight per day throughout the growing season (late spring to early autumn). When the temperature falls in the winter, it is better for the tree to receive more indirect sunlight for the majority of the day. In the early morning hours, a few hours of direct sunlight are sufficient to give the tree an adequate energy boost.
pruning
Swiss Stone Pine (Pinus cembra 'Glauca') should be pruned twice a year for optimal health and growth. Prune in early spring, before new growth begins, and again in late summer or early autumn. During the spring pruning session, any dead, diseased, or broken branches should be removed, and any thin, lanky growth should be selectively thinned to promote a better overall structure. During the late summer or early autumn pruning, any remaining dead, diseased, or broken branches should be removed, and any overly long branches should be shortened back to encourage a fuller, denser appearance. For best results, prune Swiss Stone Pine a little at a time, instead of taking off too much at once.
