Chinese wingnut

Pterocarya stenoptera

Chinese wingnut (Pterocarya stenoptera) is a deciduous tree native to China and Japan, growing up to 25m tall and 25cm in diameter. Its bark is grayish-brown and scaly. The leaves are 6-15cm in length, oblong to elliptic, and double toothed on the serrated margins. The flowers are monoecious, small and yellow-green in color, blooming from May-October. The fruit is an oval, winged nut, hence its name. The nut has edible, sweet-tasting, oily kernels, which can be eaten raw or roasted. Chinese wingnut is used in an ornamental capacity due to its stunning fall foliage, light green male catkins, and the large nuts that hang from the branches. It is best grown in full sun and moist, well-drained soil.

watering

Water Chinese wingnuts (Pterocarya stenoptera) deeply about once every 10 to 14 days when the plant is actively growing and there is no rainfall. Make sure the ground is watered thoroughly to a depth of at least 18 inches. In hot or dry conditions, you may need to water more frequently, as these plants are quite drought tolerant and usually don't need daily watering.

sunlight

Chinese wingnut (Pterocarya stenoptera) plants need full Sun during the morning and afternoon hours. They do best in the sunniest part of the garden, and should be protected from the wind. They prefer a minimum of 6 hours of direct sun each day and will become leggy and sparse if they are given too little light. If grown in containers, make sure the pot is placed in a spot that gets at least 4 to 6 hours of direct sun at some point during the day.

pruning

Chinese wingnut is a deciduous tree that should be pruned in late winter, when the tree is in its dormant state. Pruning should be kept to a minimum and should only be done if the tree shows signs of disease, has dead or broken branches, or is growing out of control. The best approach is to thin out some of the old, weak or overcrowded branches, so as to allow for better air circulation as well as increase sunlight penetration into the canopy. When pruning, make sure to remove branches that are clear of any buds so as to prevent any potential fruit production. It is also important to make sure that the cuts are neat and smooth to avoid any kind of wounding of the wood.
