Sinojackia rehderiana

Jacktree is a species of deciduous tree found in East Asia. It grows up to 25 feet tall, with a broad, open canopy and a straight or slightly contorted trunk. Its dark brown bark is scaly looking and deeply ridged. The foliage is dense and green during the summer, providing ample shade. In autumn, the leaves turn yellow and orange, providing beautiful contrast against its backdrop. The fragrant white flowers of jacktree are a special treat, appearing in Spring and then fading away in summer. It is hardy and drought tolerant, making it a great choice for gardens or landscapes, providing texture and colourful foliage year-round.

watering

Jacktrees should be watered moderately but consistently. They should be kept in moist, but not soggy soil. During the spring and summer months, Jacktrees should be watered when the top inch of soil feels dry to the touch. In the winter months, Jacktrees should be watered much less frequently--allowing the top layer of soil to dry out completely before watering again. During periods of extreme heat or drought, Jacktrees may require more frequent watering so that their soil remains moist.

sunlight

Jacktree (Sinojackia rehderiana) is a deciduous tree that requires full sun for optimal growth and health. It should be planted in a location that receives at least 6 hours of direct sunlight a day but preferably more. The best time to receive this sunlight is 8am to 6pm, in the warmer months of Spring and Summer. Avoiding direct sunlight in the afternoon, especially during the hottest part of the day, will help to reduce water loss in the leaves and help the tree to thrive.

pruning

Jack trees should be pruned from late fall to early spring. Pruning should be light so that only dead wood and light shaping of branches is done. It is important not to prune too much as this will affect the shape and health of the tree. Trees should be pruned to help enhance its structure and not to drastically reduce the size or foliage. This will also encourage the plant to grow outward, rather than inwards, and should retain its natural shape. Young Jack trees should be pruned regularly in their first years of growth as this promotes strong, healthy branching. Pruning should be done moderately and thoughtfully with an emphasis on strengthening central leaders while removing crossing, rubbing and dead branches.
