Cedar-Apple Rust

Cedar-Apple Rust disease is a very common disease which affects cedar trees, junipers and apple trees. It is unique because in order for it to perpetuate itself, it must alternate between an apple tree and a cedar or juniper tree. It is therefore important to treat all apple trees, junipers and cedar trees in an area, regardless of whether they are yet showing symptoms.

The symptoms of Cedar-apple Rust are most identifiable on apple trees. In the mid to late spring small pale yellow spots appear on the upper surfaces of the leaves. As the season progresses the spots grow in size and small black or brown spots develop in the centre of the larger yellowish spot. As the spots develop and the tree comes under more stress, leaves and fruit will drop prematurely. Cedar-apple Rust is common on both fruit-producing apple trees as well as ornamental flowering apples.

In the spring the fungal spores from the brown and red galls on juniper or red cedar trees are blown by the wind on to the leaves of apple trees where the spores infect the apple tree and rapidly multiply during wet periods. As the season progresses, the fungal spores from the apple tree are blown back on to juniper and red cedar trees where a new infection takes place.

Recommended Steps to Control Cedar-apple Rust

Cedar-Apple Rust cannot be controlled during the active growing season after it has already infected the tree. It is, however, a good idea to apply a fungicide spray during the growing season on the infected tree, as well as surrounding cedar and juniper trees, so as to reduce the degree of infection and re-propagation. During the growing season spray all of the infected and uninfected cedar, juniper and apple trees with Monterey Complete Disease Control. Repeat the spray a second time in about 14 to 21 days.

The following spring spray the trees (especially the apple tree) with Monterey Complete Disease Control. The first spraying should occur when the tree flowers; the second spray should be applied when about 75% of the flower petals have dropped; and the third spraying should occur about 10 to 14 days later.

TreeHelp developed easy-to-use Annual Care Kits to help homeowners maintain healthy and vibrant trees.

TreeHelp Annual Care Kits provide health supplements that are specific and appropriate to the type of tree that you care for. The supplements are designed to promote root-development which will have a lasting effect on the long-term health of your trees. Root development is vital for a tree because it gives the tree a reserve of strength and vitality that will help it survive through periods of drought, nutrient deficiency, insect infestation or disease. Too many fertilizers and other soil additives on the market focus on immediate impact - like "candy for trees". Our soil treatments, on the other hand, provide nutrients and organic elements that will help your tree today and for many years to come.

Some of our more popular kits include:

Palm
Contains 5 Complete Fertilizer spikes with high amounts of Manganese, Magnesium and Potassium, crucial to palm tree health.

Citrus
Contains specialized citrus fertilizer spikes loaded with micronutrients to improve tree health and fruit production

Birch
Birch trees are vulnerable to devastating insects such as Bronze Birch Borer. ?ÿThe Birch Kit is designed to promote stronger growth that helps make your tree less susceptible.

Customized kits are also available for over 90 other types of trees.

Having the right composition of minerals and organic material is extremely important in maintaining tree health. As a result, all of our kits are "custom-built" with specially selected components to suit a particular tree type. For example, the mycorrhizal fungi that benefits an oak tree will have no effect on a maple. And the fertilizer recommended for use on a pine would not be ideal for an elm. With our custom care kits, you can be certain you are applying the right treatments to your trees.

Step 1: Mycorrhizal Fungi

Mycorrhizal fungi is a relatively new soil treatment for trees. Co-existing with trees and plants in nature for hundreds of millions of years, these beneficial fungi provide a "safety net" for the tree in times of stress. By colonizing the roots and extending themselves further into the soil, the fungi enable the tree to take in more nutrients and moisture. The result is a healthier, more robust tree better capable of withstanding the many stressful conditions that exist in an urban environment and to better metabolize nutrients.

Because trees are often transplanted into non-native soils, and because urban soils have often been damaged by pollution and compaction, it is essential to re-introduce mycorrhizal fungi to the soil. Our custom care kits match the correct type of mycorrhizal fungi with specific types of trees.

Step 2: Fertilizer

Fertilizer will always be an important component of a comprehensive tree care program. But it must be done properly. Nutrient balances are difficult to achieve and improper fertilization can have drastically poor effects on trees. All too often, trees are fertilized with Nitrogen-rich, quick-release fertilizers. Not only does this have the potential of 'burning' the soil around the roots, it can also promote structurally weak growth that can attract insects and disease. Our fertilizers, on the other hand, slowly release a carefully measured balance of nutrients into the soil for a constant feeding that provides more long-lasting benefit to your tree.

The fertilizers that are included in our custom care kits have been specially selected to provide maximum benefit to a particular type of tree. The formulations are often very different from species to species and target different biological structures. The result will be a healthier, more vital tree.

Step 3: Biostimulant

TreeHelp Bistimulant is a dry, water-soluble green-up powder that is watered on tree roots as a root drench. BioSurge provides benefits to all types of trees, shrubs, and other garden plants. It is designed to increase the microbial activity in the soil around the root zone and encourage root and lateral bud development, improve the efficiency of a plant’s respiratory and photosynthetic systems and delay the aging process in plant tissue. The unique composition of ingredients includes beneficial bacteria, as well as humic acids extracts, soluble sea kelp, yucca plant extracts, amino acids and vitamins.
