Arborvitae trees are a type of evergreen that is often used for privacy screens and hedges. They grow well in USDA zones 3 to 8, so they can be grown just about anywhere in the country. These plants have some special needs when it comes to fertilization, so this article will outline how you should be caring for them and what nutrients they need.
What are arborvitae trees and what does it need to grow best?
Arborvitae trees are evergreen plants that come from the cypress family. They are generally small to medium-sized trees and make great additions to landscapes for their ornamental value. Arborvitae trees need well-drained soil, full sun, and regular watering for best growth.
What are the advantages of fertilizing with arborvitae trees?
Arborvitae fertilizing can help to promote vigorous growth, improve overall tree health, and increase the longevity of the tree. Fertilization with the proper nutrients will also encourage denser foliage and a more attractive appearance. Additionally, fertilization can help to reduce susceptibility to pests and diseases.
Which NPK ratio should you choose for your arborvitae?
There are a number of different NPK ratios available on the market, so it is important to do your research and find one that is suited for your arborvitae. The most common ratios are 11-7-7, 10-20-20, and 12-10-10.
When choosing an NPK ratio, be sure to consider the size of your tree and its current stage of growth. If you have a smaller tree, you may want to go with a lower nitrogen content (11-7-7) so as not to overfertilize it. On the other hand, if you have a larger tree that is in need of more nutrients, then you may want to go with a higher nitrogen content (12-10-10).
When should you fertilize your arborvitae tree?
The best time to fertilize an arborvitae tree is in the spring before new growth begins. However, if you missed that window or your tree has already started growing for the year, you can still fertilize it later in the summer. Be sure not to fertilize arborvitae late in the fall or winter though, as this can promote new growth that may be susceptible to cold damage.
How do you fertilize an arborvitae tree?
Fertilizing arborvitae can be done in two ways: by applying a granular fertilizer around the base of the tree, or by spraying a liquid fertilizer directly on the leaves. When using a granular fertilizer, you’ll want to apply it evenly over a radius of about three feet from the trunk. With a liquid fertilizer, you should spray it until the leaves are wet, but be careful not to get any on the trunk—this could cause burns.
