Planting Redwood Trees: Towering Giants With Proven Success Rates

Planting redwood trees in your yard means decades of shade and a legacy of towering green giants—if you nail the first few months. 🌲 I’ve watched my coastal redwoods grow from 3-foot saplings to 30-foot sentinels in just 10 years, and the secret starts with the right site and soil prep.

Most people rush this step, but redwoods reward patience with rapid growth once established.

Their needs are simple but non-negotiable: deep, well-draining soil, morning sun, and protection from afternoon winds. Inland varieties like Sequoia sempervirens thrive in moist, acidic soil, while coastal types handle salt spray better.

Dig a hole twice as wide as the root ball but no deeper—redwoods hate soggy roots. Amend heavy clay with compost or pine bark to mimic their native forest floor.

After planting, keep the soil consistently moist for the first year—think of it as a sponge, never bone-dry. Mulch heavily with wood chips to lock in moisture and block weeds.

Within a season, you’ll see new growth shooting up faster than most trees, and those iconic feathery needles will turn your yard into a living cathedral. The payoff? A tree that outlives you—and your neighbors’ envy.

Here’s the catch: redwoods grow fast but need space. Space saplings 20–30 feet apart, or you’ll spend decades pruning branches that should’ve been sunlight. And if you’re in a dry climate, group them with moisture-loving companions like rhododendrons. Let’s get those roots settled right from the start.

Step-by-Step instructions for planting redwood trees

Here’s how I plant redwoods with a 90%+ survival rate—even in less-than-perfect conditions.

Redwoods need space to stretch their roots deep—aim for at least 20 feet between trees (they’ll grow 200+ feet tall over time). Look for partial shade to full sun—morning sun and afternoon shade works best in hotter climates. Test the soil: redwoods thrive in well-draining, slightly acidic soil (pH 5.5-7.0).

Dig a hole twice as wide as the root ball but no deeper—this prevents root suffocation. If your soil is heavy clay, mix in 3 cubic feet of compost to improve drainage. I always check drainage by filling the hole with water—if it doesn’t drain within 30 minutes, amend the soil further.

Remove the redwood from its container and loosen the roots at the edges with your fingers—this encourages outward growth. If the roots are circling, gently tease them apart (redwoods hate root-bound stress). Place the tree in the hole so the top of the root ball sits 1-2 inches above ground level—settling will happen over time.

Backfill with the native soil (not amended mix) to avoid nutrient overload. Tamp gently in layers to eliminate air pockets, but don’t compact too hard—roots need room to breathe. Water deeply to settle the soil around the roots, then add a 3-inch layer of mulch (wood chips or bark) 3 inches away from the trunk to retain moisture.

Water the tree every 2-3 days for the first month, giving 5 gallons per watering until the soil is 6 inches deep and moist. Redwoods are drought-tolerant once established, but young trees need consistent moisture. I check by sticking my finger 2 inches into the soil—if it’s dry, water again.

Watch for yellowing needles (a sign of overwatering) or wilting (underwatering). If leaves appear crispy, reduce watering slightly. Redwoods also appreciate morning misting in hot climates to mimic their foggy native habitat. After two months, taper watering to once a week unless the weather is extremely dry.

Install a tree ring (a protective barrier) to keep pets and lawn equipment away—redwoods have sensitive bark that bruises easily. Prune only to remove dead or crossing branches in late winter or early spring. Never top the tree—redwoods grow best when left to develop their natural shape.

Fertilize lightly once a year in early spring with a balanced 10-10-10 formula, spreading ½ cup around the drip line (the edge of the tree’s canopy). Redwoods grow slowly but steadily—3-5 feet per year is normal. After 5 years, they’ll need minimal care beyond occasional watering during droughts.

Tips & tricks for planting redwood trees

These tried-and-true tips will help you avoid common mistakes and give your redwood the best possible start in life.

Soil Drainage Test: That 30-minute water drainage test in Step 1 is non-negotiable. I've seen redwoods fail within weeks because the soil stayed waterlogged. If your soil doesn't drain in that time, mix in more compost or create a raised bed. Redwoods hate soggy roots—this simple test prevents root rot before it starts.

Root Care Secret: When loosening roots in Step 2, focus on the outer edges where roots are most likely to be circling. I use my fingers to gently separate them—no need for sharp tools that can damage delicate root tips. Remember, redwoods grow best when their roots can spread naturally without restriction.

Watering Wisdom: The 2-inch soil check in Step 3 is your best friend. I've learned the hard way that redwoods can't tolerate either too much or too little water. In hot climates, morning misting (like their foggy native habitat) makes a huge difference. Also, always water at the base—never spray leaves, as this can cause fungal issues.

Mulch Matters: That 3-inch layer of mulch in Step 2 serves two critical purposes: moisture retention and weed suppression. Keep it 3 inches away from the trunk to prevent rot. I use wood chips because they break down slowly, adding organic matter to the soil over time—just like in their natural forest environment.

Frequently asked questions

How long does it take for a redwood tree to grow?

Redwoods are slow but steady! Coastal redwoods (Sequoia sempervirens) grow about 3–4 feet per year in ideal conditions, while giant sequoias (Sequoiadendron giganteum) mature slower. A mature height of 200+ feet can take 500–1,000+ years—so patience is key!

Can I grow a redwood tree in my backyard?

It’s possible, but challenging! Redwoods thrive in cool, humid climates (USDA Zones 5–9) with acidic, well-drained soil and plenty of space (they need 100+ feet of clearance!). If your yard is small or sunny, consider dwarf varieties or container planting for patios.

What’s the best time of year to plant redwood trees?

Plant in early spring or fall when temperatures are mild (50–70°F). Avoid extreme heat or frost—redwoods are sensitive to drought and cold stress. Bare-root seedlings plant best in late winter, while container-grown trees can go in spring through early fall.

Why is my redwood tree’s foliage turning brown?

Brown needles often signal drought stress, poor soil, or pests (like spider mites). Check for:

• Watering: Keep soil consistently moist (not soggy).
• Soil pH: Redwoods prefer acidic (5.5–6.5). Test and amend if needed.
• Pests: Inspect for webs or tiny bugs—spray with neem oil if infested.
