Best Fertilizer For Arborvitae

Arborvitae is a popular ornamental shrub that is used in landscaping and as a hedging plant. It’s also a great plant to have around the home, especially if you’re looking for something that can grow in low light conditions. Arborvitae is hardy and can withstand cold temperatures, making it ideal for colder climates.

When it comes to fertilizing your arborvitae, you’ll want to make sure that you do so once every two months during the spring and summer seasons. If you’re growing your arborvitae indoors or in an area that doesn’t get much sunlight, then you’ll want to fertilize it once every month during these periods of time as well.

In order to give your arborvitaes the best chance of growing a lush, beautiful tree, fertilize them once a year with a granular fertilizer made specifically for them. There are several kinds of fertilizers to choose from, including a slow-release NPK, 5-3-3 NPK, Jobe’s Evergreen Fertilizer Tree Spike, and Espoma’s Plant Tone.
