How to Care for Arborvitae Bushes

The first step to learning how to care for arborvitae bushes is understanding their core requirements.
 
These plants aren’t fussy, but they do have a few must-haves.
 
Here’s what they need to flourish.

Sunlight Needs for Healthy Arborvitae Bushes

Arborvitae bushes need at least six hours of direct sunlight daily.
 
When you’re figuring out how to care for arborvitae bushes, full sun is non-negotiable.
 
Too much shade makes them lose density and turn brown on the inside.
 
If your bushes are planted in a shady spot, consider moving them to a sunnier location.

Watering Arborvitae Bushes the Right Way

Water deeply and consistently, especially during the first two years after planting.
 
Knowing how to care for arborvitae bushes includes understanding their thirst.
 
They like evenly moist soil but cannot tolerate standing water.
 
A good rule is one inch of water per week from rain or irrigation.
 
During hot dry spells, increase watering to keep your arborvitae bushes happy.
 
Mulching around the base helps retain moisture and keeps roots cool.

Soil and Fertilizer for Thriving Arborvitae Bushes

Arborvitae bushes prefer well-draining loamy soil with a slightly acidic pH.
 
Part of learning how to care for arborvitae bushes is feeding them right.
 
Apply a balanced slow-release fertilizer in early spring before new growth begins.
 
Avoid over-fertilizing, too much nitrogen can cause rapid weak growth that attracts pests.
 
A light top-dressing of compost each year also works wonders.

Pruning Arborvitae Bushes for Shape and Health

Pruning is a key part of how to care for arborvitae bushes.
 
These evergreens don’t need heavy cutting, but light maintenance keeps them dense.

When to Prune Arborvitae Bushes

The best time is late winter or early spring before new growth pushes out.
 
Another window is midsummer after the first flush of growth hardens off.
 
Don’t prune in late fall because fresh cuts won’t heal before frost arrives.

How to Prune Arborvitae Bushes Correctly

Always cut back to a branch with green growth, never into bare wood.
 
Arborvitae bushes don’t regrow from old brown stems.
 
Use sharp bypass pruners for small branches and loppers for thicker ones.
 
Shape the bush so the base is slightly wider than the top to let sunlight reach the bottom.
 
This simple technique is essential for how to care for arborvitae bushes and prevent brown patches.

Protecting Arborvitae Bushes From Winter Damage

Winter can be tough on arborvitae bushes, especially in cold or windy zones.
 
Learning how to care for arborvitae bushes includes winter protection.

Wrap or Burlap for Snow and Ice

Wrap young or vulnerable bushes loosely with burlap to shield them from heavy snow and drying winds.
 
Don’t use plastic because it traps moisture and invites rot.
 
Tie the burlap gently so you don’t break branches.

Water Well Before the Ground Freezes

Give your arborvitae bushes a deep watering in late fall before the soil freezes.
 
This helps them stay hydrated through winter dormancy.
 
Dry winter winds can cause “winter burn,” turning needles brown.
 
Proper fall watering is a simple way to master how to care for arborvitae bushes year-round.

Antidesiccant Sprays for Extra Protection

You can also apply an antidesiccant spray in late fall to reduce moisture loss.
 
Follow the product instructions carefully.
 
This extra layer can save your arborvitae bushes from harsh winter stress.

If the brown is on the windward side, consider a windbreak.
 
Trim off dead sections to keep your arborvitae bushes looking tidy.

Pests Like Bagworms and Spider Mites

Bagworms can defoliate an arborvitae bush quickly.
 
Hand-pick the bags in late fall or early spring before eggs hatch.
 
Spider mites cause stippling and webbing, especially during hot dry weather.
 
A strong blast of water or insecticidal soap usually controls them.
 
Regular inspection is part of how to care for arborvitae bushes the right way.
