Washington Hawthorn Information

If you are thinking of growing a Washington hawthorn, you’ll find a lot to love in this native deciduous tree. It offers fragrant spring flowers that attract butterflies and bright fruit called haws that wild birds love. These hawthorns are also lovely in autumn. The green foliage blazes into shade of orange, scarlet, crimson and purple.

Washington hawthorn trees don’t get taller than 30 feet (9 m.) tall. Cultivated specimens can be considerably shorter. Those thinking of growing Washington hawthorn will want to know that the branches have large spines, however. That makes them good candidates for a defensive hedge but probably not a good idea if you have pets or small children running around.

Washington Hawthorn Care

Before you start planting a Washington hawthorn, be sure you are in an appropriate hardiness zone. Washington hawthorn trees thrive in U.S. Department of Agriculture plant hardiness zones 3 through 8.

Instructions on how to grow a Washington hawthorn are not complex. Plant the tree in moist, well-draining soil in a full sun location. If you find the optimal site, Washington hawthorn care and maintenance will be minimal.

These trees require regular irrigation after planting. When the root system is established, their demand for water diminished. Still, moderate irrigation remains part of its routine care.

Like other hawthorn trees, Washington hawthorns are susceptible to attack by many types of insects and a variety of diseases. Preventing or dealing with these is crucial. Pests that attack these trees include aphids and pear slugs (sawfly larvae), but these can be eliminated by spraying water from a garden hose.

Borers only attack weak trees, so avoid this pest by keeping your hawthorn vigorous and healthy. The trees can also be attacked by leaf miners, lace bugs and tent caterpillars. Spider mites can also be a problem, but all of these pests can be treated if detected early.

In terms of diseases, Washington hawthorn trees are susceptible to fire blight. Look for brown branch tips that appear scorched. Prune out diseased branch tips a foot or two beyond the blighted wood. Leaf blight and cedar hawthorn rust can also cause problems.
