An Arborist’s 10 Best Tips for Controlling Fusarium Wilt

fusarium wilt

Fusarium wilt is a fungal disease that can infect a wide range of trees, including maple, oak, and elm. The fungus attacks the tree’s vascular system, which can cause wilting, yellowing, and eventual death of the tree. It is important to take steps to control this disease to keep your trees healthy and beautiful.

Here are the 10 best tips for controlling Fusarium wilt:

1. Proper Tree Selection

The first step in controlling Fusarium wilt is to select trees that are resistant to the fungus. Some species of trees, such as red maples, are more susceptible to the disease than others, such as sugar maples. When selecting new trees for your property, be sure to choose species that are known to be resistant to Fusarium wilt.

2. Proper Planting Techniques

Proper planting techniques can also help to prevent Fusarium wilt. When planting new trees, make sure to dig a hole that is at least twice as wide as the root ball and just as deep. This will give the roots room to spread out and establish themselves properly. Also, be sure to plant the tree at the same depth it was growing in the nursery.

3. Proper Watering

The fungus thrives in moist soil, so it is important to keep the soil around your trees well-drained. Water your trees deeply and infrequently, rather than shallowly and frequently. Also, make sure not to over-water, as this can lead to waterlogged soil.

4. Proper Pruning

The fungus can enter a tree through wounds, so it is important to minimize the number of wounds on your trees. Prune your trees during the dormant season, when the tree is less susceptible to infection. Also, be sure to sterilize your pruning tools before and after each cut to prevent the spread of the fungus.

5. Proper Fertilization

The fungus can weaken a tree, making it more susceptible to other diseases and pests. Fertilize your trees with a balanced, slow-release fertilizer to promote healthy growth.

6. Mulch

Mulch helps to retain moisture in the soil and suppress weed growth. Use a 2- to 3-inch layer of organic mulch around the base of your trees, being sure to keep it at least 6 inches away from the trunk.

7. Proper Drainage

The fungus thrives in moist soil, so it is important to ensure that the soil around your trees drains well. If you notice that water is pooling around the base of your trees, consider installing drainage systems such as French drains or swales.

8. Crop rotation

Crop rotation is a great way to prevent Fusarium wilt. The fungus can survive in the soil for several years, so rotating crops can help to break the life cycle of the fungus. If you have a vegetable or flower garden, rotate your crops each year to reduce the risk of Fusarium wilt.

9. Remove and destroy infected plants

Another way to prevent Fusarium wilt is to remove and destroy any infected plants. The fungus spreads easily through the soil, so it is important to remove any infected plants as soon as possible. If you notice signs of disease on your trees, contact an arborist for assistance in removing and disposing of the infected plant material.

10. Use fungicides

Finally, you can use fungicides to help control Fusarium wilt. Fungicides are chemicals that can prevent the growth of fungi and other plant diseases. However, it is important to note that fungicides should be used as a last resort, as they can be harmful to plants and the environment if misused. If you do decide to use fungicides, be sure to follow all label instructions carefully.

By following these steps, you can reduce the risk of Fusarium wilt on your trees and help keep them healthy and strong.

How Does Mistletoe Harm Your Trees

Mistletoe Removal

Do you have mistletoe on your property? If you have mystyldene, all-heal, bird lime, golden bough, or devil’s fuge, then yes. You have mistletoe.

It’s leaves are part of a fun Christmas tradition that encourages you to a kiss while standing under it. But it’s actually very harmful to your trees. Although the evergreen plant is quite beautiful with the fragrant flowers it produces in winter, this poisonous berry does more harm than good.

Mistletoe is native to Nevada, California, Arizona, Baja California, as well as Sonora and Sinaloa, Mexico. Mistletoe is a semi-parasitic pest that grows on branches of deciduous trees, which his why you’ll want to have it removed by a professional.

How Does Mistletoe Harm Trees?

Mistletoe is a semi-parasitic plant that sends out its root-like structure into tree branches. This small evergreen shrub then steals necessary water and nutrients from its tree host. The mistletoe then continues to grow larger as it continues to damage the tree.

Although mistletoe spreads slowly, when not stopped it can be harmful to trees. When a tree is infested with the plant, it can become stunted, less vigorous and even be killed if additional stressed from other environmental factors are present. Things like root damage, drought, insect infestation, extreme temperatures, disease and mistletoe infestation can all kill an otherwise healthy tree.

If you see that mistletoe is growing on your trees, you can prune out the infested branches. But just cutting it with the branch won’t kill mistletoe; it’ll only slow down its growth. You can’t get rid of mistletoe unless you remove all the infected limbs of the tree. Special care must been taken to avoid over pruning, which is why you want to hire a professional arborist to walk this fine line for you. 

A professional arborist prune in a way that balances your need to eliminate mistletoe with your trees need to retain branches. At the same time they can also aid the tree in it’s recovery. Removing other stressors from your trees can help ensure their recovery and resistance to future infections.

The Ideal Time to Remove a Tree

Berkeley Tree Removal

The best time to remove a tree is in their dormant season, which generally includes February and March. This is the time when tree service companies are least busy, so it can be convenient and save you money too. You can remove a tree at any time of the year in an emergency, of course. When planning ahead, the dormant season and your arborist’s least busy season is the best strategic choice.

What Else Should I Consider Before Scheduling to Remove a Tree?

Many people assume that tree removal, when the future health of your tree is of no importance, is a job that anyone can do, so the cheapest bid is the best choice. There are many reasons this isn’t true. The best choice for tree removal is always the company with the best trained staff and the highest standards of cleanliness. Here’s why:

Have Your Tree Removed by the Best Trained Staff

Knowledge and skill level actually does matter when removing trees. Not because of the future of your ex-tree, but because of the future of your property. An experienced crew overseen by a Certified Arborist is ideal to ensure your underground cables, sewage, drainage, and other important features of your property below ground are safe. In experienced crews also pose a threat to above-ground property that can be hurt by falling tree parts or careless use of equipment.

Why a Cleanly Arborist Matters

A high-quality tree care team will regularly sanitize equipment to prevent transfer of dangerous infections. These can came from other people’s sick trees to your property. They also limit the spread of invasive species to your property through seeds, fruit or cuttings on their vehicles or equipment. Because tree care companies regularly interact with so many healthy and unhealthy trees, you need to know that the company you work with takes steps to stop the transfer or harmful diseases and invasive plants.

Sycamore Tree Care and Illness

Tree Care Concord

An American Sycamore tree is most notable for its exfoliating bark. People love the peeling patches on sycamore trunks.

Healthy Sycamore Trees

The bark of the trunk and its larger limbs tend to flake off in large, irregular masses, giving the surface a mottled look. The bark can be of many colors due to this, from grey to brown to greenish white. The smaller limbs often look whitewashed.

The leaves of these trees are pale green in color. When fully grown they become a bright yellow color on top and a paler yellow underneath. They become a brown color in autumn and wither just before falling away.

A sycamore tree can grow to quite massive proportions. American sycamore trees tend to be divided nearer to the ground into many secondary trunks that are free from branches. The limbs spread out at the top to make an irregular, open crown. The roots are fibrous and it’s noteworthy that trunks of the larger sycamore trees tend to be hollow.

Threats to Your Sycamore

Sycamores are vulnerable to diseases and also insect parasites, similar to almost every category of trees you could plant. As first line of protection, you should keep your tree healthy with good prevention and maintenance care. If your tree is very healthy, it’s much less likely to struggle with health issues. Of course, well irrigated and fertilized sycamore trees can be affected by diseases and pests, too.

Lace Bug

Lace bug is one of the most common and harmful sycamore tree parasites. The lacy pattern on the adult’s chest, wings, and head earn it’s name. The insects eat the under sides of the tree’s leaves.

While the sycamore lace bug’s damage is not always serious, a heavy infestation will slow the tree’s growth. You should wash off bugs with a hose. Insecticides are also readily available for this. 

Sycamore Anthracnose

Sycamore Anthracnose is a fungus that winters on twig tissue and causes leaf spots. It’s also called leaf and twig blight, and can kill American Sycamore trees while doing only minor damage to other types. A frequent clue is crinkling and browning of the leaves. Symptoms include tan to red-brown lesions extending along the veins and edges of the leaf.

Considerable defoliation, sometimes with complete leaf loss, occurs on many trees by late spring in cool, wet years. This sycamore tree disease is more likely to strike in wet weather. Rainfall and wind spread the fungi’s spores.

For Sycamore Anthracnose, we use an Arborjet treatment called PHOSPHO-jet applied in the fall following leaf coloration or early spring prior to twig infection. Propizol applied in the fall will slow the spread of infection the following spring and help the tree to grow leaves more normally.
