Pinus flexilis 'Vanderwolf's Pyramid'

Vanderwolf's Pyramid Pine is an evergreen coniferous tree native to the western United States. This slow-growing pyramidal shrub has bluish-green needles that are slightly twisted and slightly blunted at the tips, growing up to 2-3 inches long. This unique species was discovered by Leo C. Vanderwolf in 1910, and it is still popular today, due to its attractive cone-shaped form and the ability to quickly spread across open landscapes. It is drought tolerant and can survive temperatures of -40°F, making this an extremely versatile species for all climates.

watering

Water Vanderwolf's Pyramid Pine regularly, approximately 1-2 inches per week during growing season. Reduce watering to once every 2 weeks during summer months (June - September) when temperatures rise. During winter months (November - March), water only when the soil feels dry to the touch. Make sure to soak the soil when you water to encourage deep root growth. Also, make sure to water in the early morning to ensure it dries during the day.

sunlight

Vanderwolf's pyramid pine is a slow-growing evergreen that thrives in full sun with a minimum of 6 hours of sunshine per day. In areas of high humidity where wind protection is necessary, the plant can also tolerate light shade. To ensure optimal growth, the plant should be placed in a location that receives morning sun and afternoon shade. The sunnier the location, the fuller and bushier the pine tree will be.

pruning

Pruning of the Vanderwolf's Pyramid Pine should be done at least once a year, with more frequent pruning being needed in more active growing seasons. Pruning should be done in late winter or early spring, just before the new growth appears. Avoid pruning later than early spring to prevent any potential damage from new growth that will be curtailed when pruning is done. Prune away any dead, diseased, crossing or broken branches as well as any branches that have begun to grow towards the center of the plant. Take off no more than 25% of the total branch mass at any time. Lastly, prune any branches that are growing beyond an appropriate size or that are encroaching onto other parts of the garden or landscape.
