Companion Plants
Planting cedar trees transforms any yard into a fragrant, four-season sanctuary. đ˛ These evergreens thrive with minimal fuss, offering privacy, wildlife habitat, and that signature piney scentâespecially the Eastern Red Cedar or Western Red Cedar varieties Iâve grown over the years.
The key to success starts with well-draining soil and full sun exposure (6+ hours daily). Most cedars tolerate poor soil, but amending with compost at planting boosts early growth. Space saplings 10-15 feet apart for mature size, and avoid overwateringâthey dislike soggy roots.
Once established, cedars need little care beyond occasional pruning to shape them. Iâve seen them flourish in Zone 3-9, with new growth appearing in spring and berries attracting birds year-round. The fragrance alone makes them worth planting. Perfect for hedges, windbreaks, or standalone specimen trees.
Hereâs how to get them growing strong from day oneâno green thumb required.

Step-by-Step guide to planting cedar trees for privacy and pollinators
Here's how to establish fragrant, wildlife-friendly cedars that thrive for decades.
đą Step 1: Choose the Right Cedar Variety and Planting Site
Select a cedar species suited to your climateâEastern red cedar for dry conditions or Leyland cypress for rapid privacy screens. Both attract pollinators with their aromatic foliage. Test your soil's drainage by digging a 12-inch deep hole: if water pools after 30 minutes, amend with 3 inches of coarse sand per 1 cubic foot of native soil.
Cedars need full sun to partial shadeâat least 6 hours of direct sunlight daily. Mark the planting location with stakes to visualize the mature spread. Eastern red cedar grows 15-30 feet tall and wide, while Leyland cypress reaches 40-60 feet in ideal conditions. Space multiple plants 8-12 feet apart for a dense hedge or 20+ feet apart for individual specimens.
𪴠Step 2: Prepare the Planting Hole and Amend Soil
Dig a hole twice as wide as the root ball but only as deepâcedar roots prefer sitting slightly above ground level. Loosen the native soil at the hole's edges with a fork to encourage root expansion. Mix 1 part compost into the first 6 inches of native soil (use the 3 gallons you've prepared) to improve fertility without overwhelming the cedar's natural soil preferences.
Gently remove the cedar from its container and tease apart any circling roots with your fingers. Place the tree in the hole so the top of the root ball sits 1 inch above ground level. This prevents stem rot from sitting water. Backfill with native soil, tamping lightly every 3 inches to eliminate air pockets without compacting roots.
đ§ Step 3: Water Thoroughly and Apply Mulch
Water immediately after plantingâ1 gallon per inch of trunk diameterâto settle the soil and eliminate air gaps. For a 3-inch diameter tree, that's 3 gallons total. Use a slow watering can to avoid displacing soil. Continue watering twice weekly for the first month, then taper to once weekly once new growth appears.
Spread 2-3 inches of mulch (use the 4 cubic feet you've prepared) over the root zone, keeping it 6 inches away from the trunk. Pine straw or shredded bark works bestâit retains moisture while allowing airflow. This layer suppresses weeds and regulates soil temperature, which cedars appreciate during their first critical growing season.
âď¸ Step 4: Prune for Structure and Protect Young Growth
Wait 6-8 weeks after planting before pruningâthis lets the tree establish roots. Remove only dead, damaged, or crossing branches with sterilized pruners, cutting just outside the branch collar. Never remove more than 25% of the foliage in one season. Cedars grow best with minimal intervention, so focus on shaping only if you're creating a formal hedge.
Install tree guards (use the 4 plastic tree sleeves) around young cedars to protect them from deer and rabbits. These pests often browse new growth, and cedars take 3-5 years to develop enough foliage to deter them naturally. Secure guards tightly at the base and top to prevent animals from climbing inside.
â° Step 5: Monitor and Maintain Through the First Year
Check soil moisture weekly by inserting your finger 2 inches deepâwater when dry. Cedar roots extend 18 inches deep in mature trees, so deep watering encourages strong establishment. Fertilize only if leaves appear yellow or stuntedâapply ½ cup of 10-10-10 fertilizer spread evenly in the root zone. Too much nitrogen promotes weak, disease-prone growth.
Watch for bagworms or spider mites on new growth. Treat infestations immediately with neem oil spray (use the 1 quart you've prepared) applied in the evening to avoid harming pollinators. Cedars rarely suffer from pests when healthy, but young trees need this extra protection. By the second year, their natural fragrance and tough foliage will deter most problems.
Tips & tricks for perfect cedar tree planting
Hereâs how to avoid common pitfalls and ensure your fragrant cedars thrive for decades.
Soil Drainage Check: The 30-minute water test in Step 1 is non-negotiableâpoor drainage is the #1 reason cedars fail. If water pools, mix in that 3 inches of coarse sand per cubic foot before planting. Iâve seen cedars rot within weeks when planted in compacted clay, so take this step seriously. For heavy clay soils, consider raised beds to improve drainage entirely.
Root Ball Placement: That 1-inch elevation above ground level in Step 2 prevents stem rot, but many gardeners overlook it. Use a level to confirm the root ball sits perfectlyâeven a slight dip can cause water to pool. Iâve also found that teasing apart circling roots with your fingers (not a knife!) creates a more aggressive root system that establishes faster.
Watering Strategy: Those first two weeks of twice-weekly watering are critical, but timing matters. Water in the morning so foliage dries by eveningâcedars hate wet leaves, which invites fungal diseases. For larger trees (over 3 inches in diameter), increase to 4 gallons total to ensure deep root saturation. A soaker hose works wonders for even distribution without displacing soil.
Pest Prevention: Tree guards in Step 4 are essential, but deer can still browse if not secured properly. Bury the bottom 6 inches of each plastic sleeve to prevent animals from chewing through. Iâve also had success with commercial deer repellent sprays applied to guardsâjust reapply after rain. Remember, cedars wonât deter pests naturally for 3-5 years, so stay vigilant during their vulnerable first seasons.

Frequently asked questions
Got questions about growing cedar tree plants? Youâre not alone!
Here are some of the most common queriesâplus quick, practical answers to help you nurture these fragrant evergreens with confidence.
When is the best time to plant cedar trees?
Plant cedar trees in early spring or fall when soil temperatures are mild (50â70°F). This gives roots time to establish before extreme heat or cold. Avoid planting in summerâdrought stress can stunt growth. Pro tip: Water deeply after planting to reduce transplant shock!
How much space do cedar trees need?
Spacing depends on the variety:
- Dwarf cedars (e.g., 'Blue Rug'): 3â5 feet apart
- Medium cedars (e.g., 'Green Spire'): 6â10 feet apart
- Large cedars (e.g., Eastern Red Cedar): 15â20 feet apart
Why are my cedar tree leaves turning brown?
Brown needles often signal underwatering, overwatering, or pests (like cedar bark beetles). First, check soil moistureâcedars prefer well-draining soil. If pests are the culprit, inspect bark for holes or sawdust-like frass. Treat with neem oil or contact a local arborist. Prevention tip: Mulch to retain moisture without soggy roots!
Are cedar trees good for pollinators?
Yes! While cedars arenât a primary pollinator food source, their evergreen foliage provides year-round shelter for bees, butterflies, and birds. Pair them with native flowering companions (like coneflowers or milkweed) to boost pollinator support. Bonus: Their scent deters some pests, like mosquitoes!
Can I grow cedar trees in containers?
Dwarf varieties (e.g., 'Emerald Sentinel') thrive in large containers (15+ gallons) with drainage holes. Use a fast-draining mix (60% potting soil, 30% perlite, 10% sand). Repot every 2â3 years and move containers to partial shade in summer to prevent root stress. Warning: Containers dry out fasterâwater weekly!
Whatâs a good alternative if cedars donât grow well in my climate?
Try these low-maintenance evergreens:
- Arborvitae (similar shape, deer-resistant)
- Juniper (drought-tolerant, fragrant)
- Boxwood (compact, great for hedges)
Wrapping up and next steps
Growing cedar tree plants is a rewarding way to add beauty, fragrance, and wildlife support to your garden while enjoying natural privacy. Whether youâre drawn to their aromatic needles, pollinator-friendly blooms, or low-maintenance nature, these evergreens are a versatile choice for any landscape.
