watering

When to water: Jeffrey's pine (Pinus jeffreyi) should be watered once a week during the summer months and every 2-4 weeks during the winter months. How much to water: Each time you water, the soil should be moistened thoroughly with enough water to reach the roots, but not soggy or soaked. Try to avoid splashing water onto the needles of the tree so that its leaves don’t become overly wet.

sunlight

Jeffrey's pine requires full sunlight with at least 6-8 hours each day for optimal growth. It prefers warm climates, and is best suited to receiving 4-6 hours of direct sunlight early in the day and a few additional hours of scattered or indirect sunlight throughout the day. During the winter months, when the days are shorter, Jeffrey's pine does best with 4-5 hours of direct sunlight during the early to mid-morning hours, and additional indirect sun in the afternoon.

pruning

Pruning Jeffrey's pine is essential for keeping the tree healthy and well-shaped. The best time for pruning Jeffrey's pine is in late spring (May-June). Pruning should also be done in late summer to early fall (August-September) when tree sap production is at its peak. It's important to only prune dead branches or branches that could damage the tree. In addition, Jeffrey's pine should not be pruned more than 25% within any given year. This reduces stress on the tree and can reduce the chance of pests or diseases entering into the tree.
