Updated · Sources · How we source care data
Cathaya is a genus in the pine family, Pinaceae, with one known living species, Cathaya argyrophylla. In foliage and cone morphology, Cathaya has been considered a member of the subfamily Laricoideae, closely related to Pseudotsuga and Larix, but more recent genetic studies have suggested a closer relationship to Pinus and Picea in the subfamily Pinoideae.

How do you care for Silver Fir?
Plant Silver Fir in full sun to partial shade and water a young tree every 7–14 days until it is established. It tolerates temperatures of 0–80°F (-18–27°C).
What Is the Silver Fir?
Silver Fir (Cathaya argyrophylla) belongs to the Pinaceae family within the Cathaya genus.
Silver Fir displays a tall coniferous tree growth habit, reaching up to 100 ft tall with a spread of approximately 30 ft. Silver Fir produces small inconspicuous flowers.
Leaf size: approximately 4 inches.
How Often Should You Water a Silver Fir?
Water a young or newly planted Silver Fir 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 Silver Fir?
Well-draining acidic soil with high organic content. Good drainage is essential for Silver Fir to prevent waterlogging, which leads to root rot and fungal issues.
Where Should You Plant a Silver Fir?
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.
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 Silver Fir?
Silver Fir can spread to about 30 ft (9.1 m) and reach about 100 ft (30 m) tall. Space plants about 30 ft (9.1 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 Silver Fir?
Silver Fir 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 Silver Fir in Winter?
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 Silver Fir?
Silver Fir can be propagated through seeds, grafting.
Is the Silver Fir Toxic to Pets and Children?
Pet safety not verified
The ASPCA does not list Silver Fir, 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 Silver Fir?
Silver Fir is susceptible to aphids, spider mites, pine beetles. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.
