How do you care for Chinese Hemlock?
Plant Chinese Hemlock in full sun to partial shade (USDA zones 6a–8b) and water a young tree every 7–14 days until it is established. It tolerates temperatures of 10–80°F (-12–27°C).
What Is the Chinese Hemlock?
Chinese Hemlock (Tsuga chinensis) belongs to the Pinaceae family within the Tsuga genus. Chinese Hemlock is native to China, Taiwan, and Vietnam. Chinese Hemlock is also known as Taiwan Hemlock.
Chinese Hemlock displays a pyramidal, conical tree growth habit, reaching up to 60 ft tall with a spread of approximately 25 ft. Chinese Hemlock produces small, inconspicuous cones.
Leaf size: approximately 1.5 inches.
How Often Should You Water a Chinese Hemlock?
Water a young or newly planted Chinese Hemlock every 7–14 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established trees mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

What Soil Mix Works Best for a Chinese Hemlock?
Well-draining, acidic soil with high organic content. Good drainage is essential for Chinese Hemlock to prevent waterlogging, which leads to root rot and fungal issues.
Where Should You Plant a Chinese Hemlock?
Choose a spot with full sun to partial shade and well-draining, acidic soil with high organic content. Avoid low spots where water collects after rain.
Chinese Hemlock is suited to USDA Zone 6a – 8b.
Plant container-grown or balled-and-burlapped trees in spring or early autumn, setting the root flare at soil level, and water well after planting.
How Far Apart Should You Plant a Chinese Hemlock?
Chinese Hemlock can spread to about 25 ft (7.6 m) and reach about 60 ft (18 m) tall. Space plants about 25 ft (7.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

How Do You Prune a Chinese Hemlock?
Chinese Hemlock needs little pruning. Remove dead, damaged or crossing branches in late winter or early spring.
Don't cut back into old, bare wood: conifers in the pine family rarely sprout new growth from it. To keep a denser shape, trim only the soft new shoots in late spring.
How Do You Care for a Chinese Hemlock in Winter?
Chinese Hemlock is hardy down to USDA zone 6a, so once established it can stay outdoors through winter in that zone and warmer ones.
Water deeply in late autumn before the ground freezes — evergreens keep losing water through their needles all winter, and spread a 5–8 cm (2–3 in) layer of mulch over the root zone, keeping it away from the trunk.
Young and container-grown trees need extra protection: roots in a pot freeze much more easily than roots in the ground.
How Do You Propagate a Chinese Hemlock?
Chinese Hemlock can be propagated through seeds, cuttings. Similar propagation techniques also apply to western hemlock plant care, which shares the same genus.
Is the Chinese Hemlock Toxic to Pets and Children?
Pet safety not verified
The ASPCA does not list Chinese Hemlock, so we can't confirm whether it is safe for cats and dogs. Keep pets from chewing it as a precaution.
This is a general caution, not veterinary or medical advice. If your pet ate a plant, contact your vet or animal poison control.

What Pests and Diseases Affect the Chinese Hemlock?
Chinese Hemlock is susceptible to aphids, spider mites, scale insects. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.
