Are The Berries Safe On Awashington Hawthorn Tree – Common hawthorn, also called English, single-seeded, or single-seeded hawthorn, is an introduced tree that has naturalized in the Pacific Northwest. This small tree spreads easily through forests and open fields, often forming a dense, thorny thicket. Its abundant red berries are attractive to birds and other animals, helping to spread this tree far beyond where it is planted.

In King County, Washington, common hawthorn is classified as an unregulated noxious weed and its control is recommended in natural areas that are regenerating native vegetation and in protected forest lands and wilderness areas. areas and its removal from those areas is also recommended. This species is not on the Washington quarantine list and there is no restriction on its sale or use in landscaping. For more information, see the noxious weed lists and laws or visit the Washington State Noxious Weed Control Board website.

Common hawthorn is carried by birds into forests and open fields where it can form dense, thorny brambles that outcompete native species and make it difficult for large animals to cross. Somewhat tolerant of shade as well as drought, common hawthorn invades both open fields and woodlands in Washington, Oregon, and California. Common hawthorn is naturalized on both coasts of North America and in many states of the central and eastern United States, as well as parts of Australia, New Zealand, and South Africa. Although more common west of the Cascades, common hawthorn has spread into eastern Washington.

Hawthorn is generally a woodland understory species in its native range, but in our regions it grows well in a wide range of habitats. Riparian areas, abandoned fields and grasslands, scrub and grasslands, oak forests and other forested habitats are all vulnerable to invasion.

Introduced beginning in the 1800s, common hawthorn appears to have spread first to Oregon and southern Washington. Naturalized specimens were collected in Oregon in the early 1900s, and a collection from Wakiakum County, Washington in 1927 noted that the species was commonly established along roadsides. For more information on the common distribution of hawthorn, see the UW Burke Museum website.

Please note that this species and other species of hawthorn are legal for sale and planting in Washington.

We have a Washington Hawthorn tree. Is there any way, chemically or otherwise, to prevent the berries from setting? I have attached a photo. I believe it is Hawthorne.

Preventing or Reducing Fruit on Ornamental Trees and Shrubs “Nice fruit” is a concern for many people, including homeowners, landscapers, and park and city officials. The fruits and seeds of some trees and shrubs, such as cattail, mulberry, persimmon, and (female) ginkgo are unsightly, smelly, and have the potential to be a hazard when they fall onto sidewalks, paths, and other areas in the landscape. . Foliar sprays are available to reduce or eliminate unwanted fruit development on ornamental landscape plants, but factors such as weather, plant stress, environmental conditions, and lack of thorough application can make complete control impossible. Results will vary with each chemical designed to eliminate fruit. FACTORS TO CONSIDER BEFORE SPRAYING Trees and shrubs are typically selected for landscape use based on their ornamental characteristics, such as spring flowers, fall color, and fruit. All trees and shrubs produce some type of flowers and fruit, whether inconspicuous or showy. Fruit production is part of a plant’s natural development. A plant that produces a large amount of fruit can be a desirable ornamental feature or used for wildlife food. Despite the value of the flowering and fruiting plant, some people consider the spent flowers and falling fruit to be undesirable garbage. There are several methods for removing fruit or preventing fruiting. Manual removal of spent flowers or small fruit will work on a small tree, but is not a practical solution for large trees or extensive plantings. Chemical or hormone-type sprays are a more practical method, but spraying your tree can be expensive and time-consuming. Consider the following before deciding to spray: Amount of fruit production. The amount of fruit a plant can produce varies from year to year. Many plants will produce heavily one year and lighter the next. Insects, diseases and flower damage can reduce fruit production. Manual removal of spent flowers is one way to eliminate unwanted fruit. Removal of plants. If maintenance is an issue, does the factory guarantee maintenance? Trying to remove the fruit will become an annual expense of time and money. When all options are considered, removing the plant may be the best alternative, and replacing it with a plant that holds its fruit (ie some hawthorns and crabapples). Tree size. If the tree is too large for you to do the job yourself, you may need to hire a licensed professional to get the right results. Time of application. Whether you hire a professional or do the job yourself, it’s essential to spray at the right time for the best results. The “window of opportunity” varies depending on the species and cultivar(s) of the plant. WHEN AND HOW TO PRESS THE TIMING. The window of opportunity for chemical or hormone-type sprays is during flowering before fruit set, usually from the flower buds to the full bloom stage. It is essential to spray at this time for the chemicals to be most effective on the flower bud. Spraying before or after the flowers results in a waste of time and money. Temperature. Hormonal-type sprays are affected by weather conditions. Daytime temperatures during application should be between 60 degrees F and 95 degrees F for best results. Use correct concentrations. Too little concentration can increase fruiting. Excess hormone applications will cause damage to the plant. Spray plants without stress. Treated plants should be healthy and vigorous. Spraying stressed plants can cause additional damage to the plant. The chemical ethephon, which is used to stop fertility, breaks down into a natural plant hormone, ethylene. Plants stressed by drought, high temperatures, insect and disease problems, or environmental stress such as compacted soils, poor drainage, or improper pH will produce ethylene. Too much ethylene can be harmful to plants, causing injury symptoms such as leaf burn, stem damage or defoliation, which further weakens the plant. CHEMICALS AVAILABLE Chemicals are available to reduce or eliminate fruiting on ornamental trees and shrubs. Check with local nurseries and garden centers – spraying cannot guarantee 100% effectiveness. Follow specific label directions for application rates and safety information. •Florel® Fruit Eliminator by Monteray, active ingredient: ethephon •Fruitone or App-L-Set, active ingredient: Naphthalic acid (NAA) •Carbaryl (trade name Sevin) — this insecticide is harmful to bees

Harvesting hawthorn berries is new to me this year. They are sweet and mild if you get them at the right time, and in years past I tasted them too early in the fall. This year the Washington hawthorn was sweet and mild in late October. But by then, the single-seeded hawthorns have started to rot, so next year I’ll be looking for those in mid-October.

I owe some credit to Josh Fecteau’s recent post on hawthorns for inspiring me to try hawthorn berries again. As Josh points out, there are many species of hawthorn, perhaps 50 in New England. And, in all of North America, perhaps a thousand species, according to George Symonds (from his wonderful book Tree Identification Book: A New Method for Practical Tree Identification and Recognition

, my favorite ID tree learning guide). Fortunately, you shouldn’t be able to identify specific species. You just need to know it’s a hawthorn, because all hawthorns have edible berries. HOWEVER, like apple seeds, hawthorn seeds contain cyanide and should not be eaten. Don’t panic; just spit out the seeds.

Why bother with hawthorn? They are beautiful, interesting and delicious wild foods with known health benefits. Some people use the berries to make hawthorn jelly, but I have yet to try this. The berries, leaves and flowers can be used to make a tea. Scroll down to the bottom of the page to see how I make hawthorn berry extract.

I will describe two types here, as an example of the general characteristics. That should help you recognize a hawthorn when you see one, but ie
