Japanese white pine

Pinus parviflora 'Blue Wave'

Japanese white pine (Pinus parviflora 'Blue Wave') is a evergreen tree with an upright to spreading growth habit. Its bright green needles are arranged in clusters of five and typically have a glaucous blue-green tinting, giving the tree an overall blue-green appearance. It can reach a height of 25-30 feet and a spread of 8-15 feet. The white bark of young Japanese white pines stands out against its bright green needles, giving it a striking contrast. Its flattened, blue-gray cones add winter interest to its landscape presence. This hardy species is an excellent choice for rockeries and mixed borders.

watering

Water Japanese white pine (Pinus parviflora 'Blue Wave') once every week during the growing season. The amount of water needed should be determined by the weather; during dry and hot conditions, provide deep and thorough waterings. Make sure not to overwater, as this can lead to root rot. Provide a good soaking, until the water begins to drain from the bottom of the pot. Established trees may need less water than younger plants, but water still needs to be applied frequently during dry spells.

sunlight

Japanese white pine (Pinus parviflora 'Blue Wave') requires full sun exposure for 6 to 8 hours each day. While this species can tolerate some shade, it is important to note that it won’t thrive in deep shade, so exposure to direct sunlight for at least part of the day is essential for its growth. It is also beneficial to position the plant in a location that gets plenty of morning sunlight, as this will help it with photosynthesis and the ability to grow.

pruning

Japanese white pine (Pinus parviflora 'Blue Wave') does not require much pruning. For general upkeep and shaping of the tree, prune off any dead or damaged branches anytime of the year. It is best to prune while the tree is young in late winter or early spring before it begins to produce new growth. Removing up to 1-third of the new growth is beneficial for the healthy growth of the tree and to maintain its overall shape. Avoid pruning late in the summer as it can stress out the plant.
