Closeup of Psyllids

Arbor-wellness: Psyllids

When large trees lose their leaves in mid-summer, we tend to panic, and often for good reason. We tend to think of water problems or diseases as the main cause, but sometimes it may be a small insect that is hard to spot. Psyllids are small insects that suck plant juices and excrete sticky honeydew on which blackish sooty mold grows. Some species secrete pale or white wax masses, pellets, strands, or coverings called lerps. They affect many species of trees in our region, but the most common are Eucalyptus, peppertree, citrus, acacia, laurel and tipu or rosewood.

My eucalyptus trees are losing lots of leaves, what could be wrong?

There are several reasons why eucalyptus leaves drop their leaves in large amounts. If you see small, whitish “caps” on the leaves, this is a type of “psyllid” called “redgum lerp psyllid”. This is one many psyllid types that are common in our region.

What other damage can psyllids cause?

High psyllid populations reduce plant growth and cause tip damage, discoloration or dieback. Certain species can cause premature leaf drop. Excessive honeydew creates a sticky mess on cars and surfaces below trees.

Do psyllids damage other trees in my landscape?

There are over 160 psyllid species that occurs on landscape plants in California. Each kind of psyllid feeds only on one plant species or one closely related group of plants. Most psyllids native to California are relatively uncommon and rarely become pests. But some can cause extensive damage. These are generally psyllids that have become pests on trees that are originally from other countries. The most important tree damaging psyllids occur on acacia, eucalyptus, olive, peppertree, laurel and citrus.

I’ve heard about citrus trees dying or being taken out, is this the problem with them?

Well, sort of. A relatively new psyllid pest (Asian citrus psyllid) has been introduced into parts of California. The insect itself doesn’t kill citrus trees, but it can introduce a disease called “Citrus Greening” that is essentially fatal to them. If allowed to become widespread, it is feared the California citrus industry will be wiped out. Currently, the agencies involved are heavily involved in scouting, insect control and plant removal efforts in regions that are most affected. Being vigilant about scouting and controlling this pest when found is very critical.

What can I do?

Your Arborwell arborist can identify locations where Asian citrus psyllid, Redgum lerp psyllid (or other types) are doing the most damage and recommend a treatment program to recover your trees and to keep them healthy. They can also recommend a proper plan for citrus trees on your property if you are close to an area affected by Asian citrus psyllid.

Drought Tolerant Trees for Southern California

Arbor-wellness: Plan for 2020

Prevention Season is Starting

Fall & winter are the most valuable time to protect your trees from next season’s insects and diseases. Whether its sticky sap, borers and bark beetles, or diseases like anthracnose or fireblight, fall or winter are ideal times to protect your trees. When treated now, trees have all winter to move protective products into and throughout their stems, twigs and roots. These products will be ready to work as soon as new growth starts next spring. Many diseases infect as soon as leaves appear, so by NOT protecting now, we are essentially playing catch-up if we don’t protect trees until after they start growing. This also most sense, given the stresses our trees have had to overcome the past several years. Stressed trees are more prone to insects and diseases because their defense systems are weakened and they have a harder time protecting themselves. So along with proper pruning, watering and mulching, protecting against insects and diseases will help them become healthy again.

My trees seem to be struggling still, why is that? 

Well most likely they are still recovering from the stresses of the drought we have had. When trees are stressed, whether it is drought, lack of irrigation, flooding, or whatever stress has occurred, they reduce the output of new leaves and new roots. They don’t produce as much energy storage and they stop producing the compounds (auxins and enzymes) that they use to ward off attacks. Thus, they become more vulnerable to damage from insects and diseases.

Will they die? 

Its hard to determine that without a good evaluation from a certified arborist. That being said, providing extra “help” for them right now is very beneficial to their recovery. Just like a marathon runner that starts out in good shape, if that runner is forced to run back to back to back marathons without the time to recover well, they become more prone to injuries and illnesses. Allowing for proper recovery allows them to run another marathon (another stress) down the road. So, trees need this recovery period too, reduced stress from lack of water, excess heat, over watering and attacks from diseases and insects, so they can build their defense systems again, like we need to recover our immune systems.

How do I help them recover? 

First reduce additional stresses – proper watering, mulching, pruning are key components to helping your trees recover. Second, by proactively protecting a tree from insects and diseases, they have a further chance to build those defense systems. If an insect – like caterpillars for instance, defoliates a tree next spring, that tree has to put new leaves out a second time. The same goes for diseases like anthracnose or fireblight. The energy the tree expends by putting out a second set of leaves prevents it from building up its defense system again, thus prolonging the recover. If this weakened tree is subject to another multi-year drought cycle, the chance of it surviving is even lower.

When is the best time to treat my trees? 

Fall and early winter are the best times by far. This allows ample time for the systemic treatment to completely circulate throughout the tree. It allows the treatment to be ready as soon as spring growing season starts again.  Late winter and early spring are the second-best time. It is still early enough to have the treatment be effective under most circumstances.

What kinds of problems can you control proactively? 

Many of the most common insects and diseases can be suppresses this way.  Insects that produce sap, most boring insects, most scale and thrips, adelgids, caterpillars and twig boring insects for example. As far as diseases go, preventing is so valuable, because by the time you see a disease on a tree, the damage has essentially been done. This is true for fireblight, anthracnose, powdery mildew, root rots like verticillium and phythophera and stem and twig cankers and needle blights on evergreens.  Lastly a nutritional supplement can be applied at the same time. Many times, a tree is stressed in part because of the lack of available nutrients in the soil. We can provide a balanced, organic nutritional supplement that will give your trees a proper feeding. Or better yet, we can sample your soil and replace exactly what your trees need.

Seattle’s Urban Forest Progress and Role of Trees in the City

Well known for its wealth of forests and beautiful natural landscape, the city of Seattle is taking important steps to preserve its urban forests and ensure that they continue to thrive. They have created the Urban Forest Management Plan, which strives to maintain, improve and re-establish the urban population of trees in Seattle.

This is a complicated issue, but Arborwell Professional Tree Management believes it’s one that can and will be solved. Seattle’s urban forest progress has focused on planting and maintaining trees, as well as restoring parklands.

Why are tree so important?

Trees and forests play a very important role in our ecosystems. They absorb carbon dioxide and can store the carbon, while releasing the oxygen back into the air. This is a great way to combat the growing climate change issue. As well as providing clean air, a healthy forest can also offer habitat for wildlife, is more resistant to forest fires, reduce flooding and provide clean water, and fight back against disease and pest infestations more effectively.

Urban forests are a key part of Seattle’s ecosystem and the benefits from ensuring their health and vitality are crucial. The 2018 progress report shows that nearly 50,000 seedlings were planted, 134 acres of invasive species were removed from parklands, and over 5,000 trees were maintained to ensure continued growth.

What is Seattle’s goal?

The city of Seattle began its urban forest management plan with the goal of increasing its tree canopy cover to 30%. In a report from 2016, seen here, it was estimated that canopy cover was at 28%. The city has made great improvements to local urban forests and will continue to do so by keeping up with planting and maintenance efforts.

For owners of private estates or commercial properties in the Seattle area, the experts at Arborwell can help you with the trees on your property. We have years of experience providing excellent tree care and we can share our expertise with you.

If you are looking for a way to help with Seattle’s urban forest progress and understand the pivotal role of trees in the city, contact Arborwell today at 888-969-8733 or visit our website.

  • Tree trimming. This requires more than just chopping branches off. A professional arborist knows how to trim a tree so that it looks good and promotes new growth.
