Cytospora Canker

Have you noticed your Colorado blue or other , such as Douglas , and White looking a bit peaked in the last few years? They are probably infected with Cytospora canker, a fungal disease that attacks and kills individual branches of primarily mature spruce trees. One by one the branches begin to discolor from the bottom of the tree upward.

Cytospora is caused by the organism Cytospora kunzei . This fungus naturally occurs as a saprophyte on the dead bark of many conifers. The fungus only causes a problem when the health and vigor of the tree has been weakened by other causes such as drought or poor nutrition.

The fungus overwinters as fruiting bodies on the bark of infected tissue or as vegetative mycelium in can- kers. Infection is suspected to occur during late winter and early spring. The site of infection may be natural wounds such as leaf scars or manmade pruning wounds. The spores of the fungus are dispersed to potential host trees through splashing rain.

The resulting lesions begin at the base of the branch near the branch collar and spread along the branch in an elliptical fashion. The cankers are reddish brown and slightly sunken. There is often an excessive amount of resin covering the cankers. Removal of the bark will disclose sapwood which appears normal in color. Upon close examination, one may find tiny, black, pimple-like pycnidia which represent the fruiting structures of the fungus. It is in these black pycnidia that spores are produced which will continue the disease cycle.

Cytospora canker will not result in sudden death of the infected tree but rather, several years or decades will pass before the trunk is girdled and an affected tree will die. Dead twigs may remain on the tree for many years. Typically, trees less than 15-20 years old are not affected. However, the fungus may attack small branches of young seedlings in nursery beds.

Because Cytospora normally attacks trees under stress, it is important to prevent or eliminate any stresses on susceptible trees. Avoid overcrowding and drought. Take precautions not to injure the root system.

A fascinating read…

If you love trees and excellent writing, then The Overstory is the book for you. By Richard Jordam, it is a compilation of short sto- ries—all very different with trees playing a major role in each. Re- cent winner of the National Book Award. A Christmas Tree for All Seasons

The dwarf Alberta Spruce can be purchased online, used as a Christmas tree indoors and planted in full or part sun and well-drained soil. It attracts birds, is deer resistant, can handle high wind, heat, and cold and is even drought tolerant once established. There is no need to prune this evergreen, but it tolerates pruning well. Dwarf Alberta spruce trees are classified as evergreen conifers. The Latin name is Picea glauca 'Conica', making it a relative to the giant white that can grow as tall as 140 feet.

It is cold tolerant to minus 50 degrees F, and thrives in zones 2-8. It likes full to part sun and adapts to any soil that is well drained. A neutral to acidic soil is best. After planting, adding a layer of 2 -3 inches of mulch will help keep the soil moist. Do not allow the mulch to touch the trunk as this increases the chances of pests and disease. After the plant is established, it only needs watering when the soil is dry. This Spruce is drought tolerant after establishing. Fertilize when planting and in early spring yearly with a slow release fertilizer. If the soil is on the basic side choose a fertilizer for acid loving plants. It should be planted where it has plenty of air flow.

Once the plant is growing outside, one problem you may run into with this plant is spider mites. Spider mite damage usually results in patches of brown, dried needles. You can test for their presence by gently shaking the plant while holding a white piece of paper under the branches. The mites will appear as small, moving flecks.

To treat for spider mites first try an insecticidal soap. It is more environmentally friendly than other methods. You’ll want to saturate the foliage. It may require several applications about 7 to 10 days apart. Now if this doesn’t work, you may have to resort to harsher pesticides. Just avoid horticultural oils because they are harmful to the dwarf Alberta spruce.

Congratulations to all who have worked so hard this year, sometimes under trying circumstances. Your enthusiasm and willingness to volunteer is what makes Clinton County Mas- ter Gardens a very special group of people. Merry Christmas and a happy and healthy 2020 to all!
