Non-native invasive plants pose a serious threat to Maine&#8217;s biodiversity. Plants such as Japanese barberry, shrubby honeysuckle, and Asiatic bittersweet, originally introduced for their ornamental features, have escaped from our landscapes, colonizing natural areas and displacing native plants and animals. By landscaping with native plants, we can create vegetation corridors that link fragmented wild areas, providing food and shelter for the native wildlife that is an integral part of our ecosystem. Your landscape choices can have an impact on the environment that goes far beyond your property lines.<\/p>\n\n\n\n<hr>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Description<\/strong><\/h3>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"alignright is-resized\"><a href=\"https:\/\/extension.umaine.edu\/publications\/wp-content\/uploads\/sites\/52\/2016\/01\/ostrya-virginiana-leaves.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"300\" height=\"215\" src=\"https:\/\/extension.umaine.edu\/publications\/wp-content\/uploads\/sites\/52\/2016\/01\/ostrya-virginiana-leaves-300x215.jpg\" alt=\"Ostrya virginiana leaves\" class=\"wp-image-15877\" style=\"width:370px\" srcset=\"https:\/\/extension.umaine.edu\/publications\/wp-content\/uploads\/sites\/52\/2016\/01\/ostrya-virginiana-leaves-300x215.jpg 300w, https:\/\/extension.umaine.edu\/publications\/wp-content\/uploads\/sites\/52\/2016\/01\/ostrya-virginiana-leaves-105x75.jpg 105w, https:\/\/extension.umaine.edu\/publications\/wp-content\/uploads\/sites\/52\/2016\/01\/ostrya-virginiana-leaves-317x227.jpg 317w, https:\/\/extension.umaine.edu\/publications\/wp-content\/uploads\/sites\/52\/2016\/01\/ostrya-virginiana-leaves-423x303.jpg 423w, https:\/\/extension.umaine.edu\/publications\/wp-content\/uploads\/sites\/52\/2016\/01\/ostrya-virginiana-leaves.jpg 430w\" sizes=\"auto, (max-width: 320px) 85vw, (max-width: 768px) 67vw, (max-width: 1024px) 62vw,300px\" \/><\/a><figcaption class=\"wp-element-caption\">Photo by Reeser C.

Tolerant of full sun, <em>Ostrya virginiana <\/em>can also be used as a specimen tree in the landscape, and its small size is particularly suited to use as a patio or courtyard tree. When grown in the sun, it is likely to become wider than it is tall.<\/p>\n\n\n\n<p>Once established, <em>O. virginiana<\/em> can tolerate summer drought and heat.

Give the root zone of each tree 1 inch of water per week; in general, a tree&#8217;s root zone extends twice as wide as its canopy. After the establishment period, provide supplemental irrigation during periods of severe drought.<\/p>\n\n\n\n<p><strong>Fertilization:<\/strong> Landscape trees and shrubs should not be fertilized unless a soil test indicates a need. Correct soil pH, if necessary, by amending the backfill soil. No nitrogen fertilizer should be added at planting or during the first growing season.<\/p>\n\n\n\n<hr>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>To learn more about native woody plants<\/strong><\/h3>\n\n\n\n<p>Visit the Eastern Maine Native Plant Arboretum at University of Maine Cooperative Extension&#8217;s Penobscot County office, 307 Maine Avenue in Bangor.
