Some varieties have a fluffy look, while others have soft fanning, flattened branches, all are soft to the touch and wave in the breeze in an undulating pattern.


There are many varieties to choose from, but here are some quick facts about the most popular ones:

There are a lot more varieties to choose from here at NatureHills.com, but these two popular choices are an excellent way to start!

Continuous Care

Once you get your trees established and they’ve had the chance to grow into their new homes, it’s time to start making sure you’re continuing to give quality care to these evergreens.

These plants do enjoy their moisture, especially before the wintertime. Be sure to give them lots of moisture and water before heading into the cooler months so that you have a healthy spring tree to look forward to.

They also need protection from drying Northern winter winds. Use an anti-desiccant spray in late fall to further protect them if in an area prone to windburn.

Otherwise, these plants are fairly low maintenance. Their soil should be well-draining, and consistently moist until the roots have established themselves.

Use the “finger test” to stick your finger in the soil near the roots to the second knuckle. If it’s moist, skip watering that day. If it’s dry, give it plenty of water.

Pest & Disease Care From the Plant Sentry™ Experts

While these trees and shrubs stand tall hovering over your garden, they, 

like many other plant varieties, are at just as great of a risk as other plants when it comes to warding off insects and disease. In order to keep your trees at their healthiest, our Plant Sentry experts are weighing in to offer you expert advice on their care to keep your garden as happy and healthy as possible!

There are a few diseases that afflict this plant variety that you should be aware of:

  • Kabatina Twig Blight (Kabatina thujae): This disease causes the tips of one-year-old branches to die and turn a brown or gray ash color. These tips will remain on the plant for many months. You should prune and destroy the infected areas if found. The use of a fungicide can help protect the plant from blight.
  • Pestalotiopsis Tip Blight (Pestalotiopsis funerea): This disease causes the tips of the twigs to turn a light to dark brown color with black pimple-like fungus structures on the surface. To prevent this type of blight protect the shrubs and trees from winter damages, drought, and other stressful conditions. Like the Kabatina Blight, the use of a fungicide can help protect the plant from blight.
  • Phomopsis Twig Blight (Phomopsis juniperovora): This disease causes the tips of the branches to die, turn brown, or ash-gray. This discoloration will remain visible on the plant for many months after infection and can cause the larger branches to be girdled or infected. At the point of infiltration into the healthier wood, black, pimple-like fungal structures will grow. To remedy this infection you should prune and destroy the infected limbs. Like the other varieties of blight, applying a fungicide can offer protection against the blight.


  • The Arborvitae family can face a number of challenges when it comes to potential threats of pests. Most commonly the pests to keep an eye out for are bagworms, scale, leafminers, and spider mites. Regular treatment of your plants can help limit or eliminate pest problems that may aris
