Is it OK to trim arborvitae?

Arborvitae will withstand heavy pruning and shearing because new branches develop from concealed buds in the branch crotches. Prune in early spring or mid-summer.

What happens if you top an arborvitae?

Topping is often done when a tree's height becomes problematic. When the top of an arborvitae is cut off, however, it creates a very flat and unsightly appearance.

Why are my arborvitae turning brown in the middle?

How can I make my arborvitae grow faster?

To fertilize your trees, broadcast the recommended amount of fertilizer evenly over the root zone. Keep the granules well away from the plant's trunk area. Water the soil beneath the tree well when you are done fertilizing arborvitae. This helps the fertilizer dissolve so that it is accessible to the roots.

How do you tie arborvitae for winter?

Evergreens can be protected from snow breakage by tying the branches together with strong rope or twine before winter snows are expected, but after the first severe frost. Fasten it near the tip of the tallest branch and then spiral down around the entire tree and tie it off to the base.

How do you transplant arborvitae?

Dig around the root ball of the arborvitae with a spade. Cut the roots with a hatchet, maul or axe when the spade does not go through. Arborvitae that are 10- to 15-feet tall need a root ball of at least 3 feet in diameter. Water the plant again immediately before digging or removing from its spot.

How do you fertilize arborvitae trees?

Healthy arborvitae benefit most from annual fertilizer applied in early spring before new growth begins. Use slow-release, granular fertilizer with a higher first number, such as 12-6-4 or 10-8-6. Broadcast granules at a rate of one-third pound for each foot of the plant's height.

Will topping a pine tree kill it?

Topping spoils a pine tree's natural shape. Cutting the top from a pine won't immediately kill the tree, but a large pruning wound could leave the tree open to potentially deadly infections. Cutting out a pine's top stops vertical growth unless new leaders form.
