Chinese elm

It is important to water Chinese elms (Ulmus parvifolia 'Hokkaido') consistently throughout the growing season. The amount and frequency of watering will depend on the environment and the time of year. In general, Chinese elms prefer their soil to remain consistently moist, so water deeply whenever the top inch or 2 of soil is dry. During the hottest months of summer, you may need to water as frequently as once a week. In cooler months, water every 10-14 days. Avoid over-watering as this can stress the plant and cause root rot.

Chinese elm (Ulmus parvifolia 'Hokkaido') thrive in full sun to partial shade. When providing sunlight for this plant species it is important to ensure it has 4-5 hours of direct sunlight per day. This allows it to develop the smaller leaf-structure that it is known for, and helps it create its desired canopy shape. Too little sun can lead to stunted or lopsided growth. Too much sun can cause leaf burn. When positioned in a sunny spot during the afternoon, be sure to give the Chinese elm protection from the blazing hot sun that typically occurs in the afternoon. Late afternoon shade and morning sun is usually the ideal sunlight for this species.

Chinese elm (Ulmus parvifolia 'Hokkaido') should be pruned in late winter or early spring. The amount of pruning should be light to moderate; removing dead, diseased, or crossing branches. You can thin out the crown by removing 1/3 of some of the oldest branches. This should increase air circulation and reduce the risk of disease and insect infestations.
