What is eating my Cryptomeria leaves?
Spider mites occasionally attack Japanese cryptomeria, with spruce spider mites (Oligonychus ununguis) being the most common pest. The tiny green arachnids feed on the foliage, resulting in mottled needles that look yellow before turning bronze. The injured foliage often falls from the tree.
Does cryptomeria turn brown in winter?
Winter Browning in Cryptomeria japonica Winter browning occurs due to a phenomenon called photoinhibition that takes place under periods of high light and low temperature.

Why is my Japanese cedar turning brown?
It's a normal cycle all cedar trees go through. Here's how it works: around late summer or early fall, cedars and most conifers need to let go of older, interior needles that are no longer doing the tree much good. Those needles turn yellow/brown as the tree phases them out and makes room for new growth from the tips.
How is cryptomeria blight treated?
Solution. Cultural solutions to twig blight include removing all blighted twigs and needles and burning them. Prune the tree only when the weather is dry to avoid spreading the fungal pathogen. If you must water the tree overhead, water in the morning so the tree will dry before evening.
How can you save cryptomeria?
Provide the cryptomeria tree with plenty of air circulation to prevent disease. Pulling weeds that grow under the canopy of the Japanese cedar will help improve airflow. A 3- to 4-inch layer of pine bark or straw can help prevent weeds from growing back. Mulching also improves water retention.
Can you cut back cryptomeria?
Cryptomeria is unique in that its branches and trunk, when severely cut back, will re-row a sprout from the cut. They need not be pruned except to control the shape and size but are very resilient to pruning so do not be afraid to prune as you desire.

How do you fertilize Cryptomeria?
Fertilize cryptomeria trees in the spring using a 10-8-6 fertilizer and apply it on top of the mulch layer. Check the fertilizer package to establish the right amount to use. Water newly planted trees once a week for the first three months with 1 inch of water at each application.
What does blight look like on Cryptomeria japonica?
Leaf blight is most noticeable in the summer when the Japanese cedar should be a healthy, rich, dark green. Inner leaves turn brown first, giving the tree a thinning, unhealthy appearance. Left untreated, older twigs will turn gray and small, black cavities will develop on the upper surfaces of infected leaves.

How do you fertilize Cryptomeria?

Why do cedar trees turn brown?
Root Rot: Armillaria root rot is sometimes found in cedar hedges. Branches turn brown, often starting on one side of the tree. Fans of white fungal mycelium can be found under the bark at the base of dead trees and in the roots. Black 'strings' called rhizomorphs spread the fungus from one tree to another.
How do you prune Cryptomeria Globosa Nana?

What happens when the ground freezes?
When the ground freezes, roots can't take up moisture to replenish what's being lost through the leaves and needles.
Why do evergreens get windburn?
Evergreens are more prone to winter windburn than leaf-dropping plants because their needles continue to lose moisture to evaporation throughout winter. Broad-leaf evergreens like hollies and rhododendrons are even more prone to windburn than needled evergreens.
Do Cryptomeria evergreens discolor in winter?
Some evergreens discolor in winter, but ones that don't green up in spring most likely suffered root death. Q: A year ago, I purchased two Cryptomeria japonica 'Black Dragon' that I've been growing in large pots flanking our west-facing porch. They did quite well last summer and fall, but over the winter, they turned a coppery color.
How to control cryptomeria?
Control cryptomeria and phomopsis blight by pruning out and destroying infected needles and branches, cutting below the infection site into healthy wood to remove all of the blighted tissue. Keeping the foliage dry will prevent the fungal pathogens from germinating.
What causes a tree to turn brown?
Cryptomeria blight pathogens (Pestalotiopsis funerea) cause the foliage to first turn yellow and then brown starting at the tips of the needles. The older foliage in the lower sections of the tree typically suffer the worst damage. Cercospora needle blight pathogens (Cercospora spp.) initially cause the needles in the tree's lower sections to turn brown, gradually spreading up the tree and outward. Small, green fungal spores form on the needles and smaller twigs.
How to kill cryptomeria spider mites?
Control small populations of spider mites by spraying the foliage with a strong stream of water from a garden hose. Use a 2 percent insecticidal soap solution to treat larger populations. Following the instructions on the product's label, mix about 5 tablespoons of insecticidal soap into one gallon of water and spray the foliage thoroughly for optimal results. A 2 percent insecticidal soap solution can also help control scale populations, but you must time the application with egg hatching for the treatment to work effectively.
What are the mites on Japanese cryptomeria?
Spider mites occasionally attack Japanese cryptomeria, with spruce spider mites (Oligonychus ununguis) being the most common pest. The tiny green arachnids feed on the foliage, resulting in mottled needles that look yellow before turning bronze. The injured foliage often falls from the tree. Severe spider mite infestations might cause defoliation and twig or branch dieback. Japanese cedars can die if severe infestations coincide with environmental stress. Unlike other spider mite species, the spruce spider mite thrives in cool weather and becomes inactive once temperatures reach 90 degrees Fahrenheit.
How to treat cercospora blight?
Copper-based fungicides can effectively treat cercospora blight. Following the manufacturer's directions, mix one-half to 2 fluid ounces of fungicide into 1 gallon of water. Spray your cryptomeria tree until you thoroughly cover all of the needles and branches every 10 to 14 days from budbreak until the needles mature to a dark green color.
How to treat Cryptomeria with mites?
Spider Mites are very small and a pest that is sometimes overlooked. Take a white sheet of paper and hold it just below the foliage where it 's brown and green . Tap the green and brown branches letting whatever is on them fall down on to the white paper. If you see little orange red insects scurrying around the paper then it is Spider Mites. Treat the Mites with Malathion or Neem Oil. Neem Oil is organic and safer to use. Neem Oil also treats disease and most other insects as well.

What causes browning on a tree?
Leaf Blight is a fungal disease that will cause browning of the foliage. This disease is normally seen during periods of wet weather or as I noted when foliage is not allowed to dry in a short period of time. This disease can be spread by spores blown in the wind or splashing water possibly from sprinklers. Just to be safe the tree can be sprayed with a fungucide formulated to control leaf blight or Neem Oil.
