Pinus flexilis 'Cesarini Blue'

Limber Pine (Pinus flexilis 'Cesarini Blue') is a unique evergreen conifer that offers both year-round color and texture in the landscape. With its erect conical form and dense, dark grey-green foliage, it's an excellent choice for a feature tree in the garden. The 'Cesarini Blue' cultivar displays deep blue-green needles that are bright turquoise on the underside. In late spring, mature plants bear pearl-like, yellow-white cones. Limber Pine prefers a sunny spot and well-drained soil, and can tolerate temperatures as low as-30°F (fingers crossed). It's one of the hardiest high elevation pine trees available, making it an ideal addition to a mountain retreat.

watering

Limber Pine (Pinus flexilis 'Cesarini Blue') requires moderate watering. During the hot summer months, the soil should be kept evenly moist but not overly wet. Water whenever the top 1/2 to 1 inch of soil dries out, typically every 5-7 days. The limber pine should receive at least 1 deep watering per week that reaches deep into the root system. Water until the soil is evenly moist and water starts to come out of the drainage holes on the bottom of the pot. During the cooler months of spring and fall, the pine should be watered less frequently and allowed to dry slightly more between waterings. This will help prevent root rot.

sunlight

Limber Pine (Pinus flexilis 'Cesarini Blue') requires full sun, which is generally 6 to 8 hours of direct sunlight a day. This species of pine does best when given full sunlight throughout the day. If it is not given full sunlight exposure during the day, its growth and growth rate will be stunted. If possible, the plant should be placed in a location that can get full sunlight year-round, although limber pines can also tolerate partial shade. It prefers more sun during the spring and summer months, and can tolerate a bit more shade in the winter months.

pruning

Limber pine (Pinus flexilis 'Cesarini Blue') should be pruned in late winter or early spring, when the new growth begins. Pruning should be done lightly to thin and shape the tree. The tree should not be trimmed back beyond its natural shape as this will limit its air and light exposure, inhibiting the tree’s ability to grow and thrive. Pruning can help control the height and spread of the tree, as well as reduce the occurrence of disease or pest infestations. For larger trees, dead or hazardous branches should be pruned away to ensure the safety of passersby. In addition, any lateral branches that are rubbing against each other should be pruned away to avoid further damage to the tree.
