Can You Grow a Redwood?

Yes, you can grow a redwood tree in your yard, but the real question is whether you should. Redwoods are magnificent but massive trees that live for thousands of years, and planting one requires serious long-term planning that most homeowners overlook. Before you buy a seedling, you need to understand the space, climate, soil, and maintenance demands that come with growing one of the tallest tree species on Earth.

Is It Actually Possible to Grow a Redwood at Home?

It is absolutely possible to grow a redwood at home, and many people have done it successfully across the United States and even in parts of Europe and New Zealand. The key is matching the tree to your specific environment. Redwoods are not magic — they are hardy trees that can adapt to many conditions as long as their basic needs are met. The two main species people grow are the Coast Redwood (Sequoia sempervirens) and the Giant Sequoia (Sequoiadendron giganteum). Coast redwoods are the taller of the two, while giant sequoias grow thicker and more conical. Both can thrive in home landscapes if given enough room.

Which Type of Redwood Grows Best in a Yard?

For most home landscapes, the Giant Sequoia is the better choice. It grows more slowly than the Coast Redwood, has a more compact and pyramidal shape, and tolerates a wider range of climates and soil types. Coast redwoods are more finicky — they demand consistent fog or high humidity, mild summers, and deep, acidic soil. Giant sequoias handle drier conditions, colder winters, and less perfect soil. If you live outside the coastal fog belt of Northern California or Southern Oregon, a giant sequoia gives you a much higher chance of success.

Main Differences Between the Two Species

How Much Space Does a Redwood Tree Need?

This is where most people get it wrong. A redwood tree needs far more space than a typical yard provides. For a Coast Redwood, you need at least 30 to 40 feet of clearance from structures, driveways, sidewalks, and underground pipes. Its roots spread wide and shallow, often extending 100 feet or more from the trunk. For a Giant Sequoia, plan on at least 25 to 30 feet of clearance from all structures and hardscapes. Even the lower end of that range is a serious constraint for most suburban lots. A common mistake is planting a redwood within 10 or 15 feet of a house, which leads to foundation damage, cracked driveways, and sewer line blockages within 20 to 30 years. If your lot is smaller than a quarter acre, you should think very carefully before planting a redwood in the ground.

What Climate and Growing Zone Do Redwoods Require?

Coast Redwoods grow best in USDA Hardiness Zones 7 through 9. They need mild, humid summers and cool, wet winters. They do not tolerate extreme heat or prolonged drought without supplemental watering. If you live in an inland area where summer temperatures regularly top 95°F, a Coast Redwood will struggle unless you mist it or provide shade. Giant Sequoias are more forgiving — they grow well in Zones 6 through 8 and can handle occasional winter lows down to -20°F once mature. They tolerate hotter summers better than Coast Redwoods, but they still need reliable moisture. Both species require a climate that provides at least 40 to 60 inches of annual rainfall, or you must supplement with irrigation. The single biggest climate factor for either species is summer humidity or reliable fog. Without it, the trees dry out and fail to thrive.

What Soil and Water Conditions Do Redwoods Need?

Redwoods are picky about soil. They need deep, well-draining, acidic soil with a pH between 5.0 and 6.5. Alkaline soil or heavy clay causes yellowing leaves, stunted growth, and root rot. Before planting, test your soil with a reliable soil pH test kit to check acidity levels. If your soil is too alkaline, you can amend it with sulfur or peat moss, but this requires ongoing maintenance.

Watering is critical. Redwoods are not drought-tolerant. Young trees need deep watering at least twice a week during the first two growing seasons. Use a tree watering bag to deliver slow, deep water directly to the root zone without wasting it on the surface. Established trees still need supplemental watering during dry spells, especially in summer. A good rule is to provide about 10 to 15 gallons of water per inch of trunk diameter once a week during dry periods. Mulch heavily around the base — 4 to 6 inches of wood chips — to keep the soil cool and moist. Do not let the mulch touch the trunk itself, or you risk rot and pests.

How Fast Do Redwoods Grow in a Home Landscape?

Expect a Coast Redwood to grow 3 to 5 feet per year in ideal conditions. A Giant Sequoia grows more slowly, about 1 to 2 feet per year. That sounds slow, but over a decade the sequoia still reaches 15 to 20 feet, and the Coast Redwood can top 40 feet in the same timeframe. This growth rate surprises many homeowners. What looks like a small, manageable sapling today will become a 50-foot tree in 15 years. If you plant one, you are committing to having a very large tree on your property for the rest of your life and likely beyond. Keep a record of where you plant it, and inform future owners of your home. The tree will outgrow its welcome surprisingly fast if you do not plan ahead.

What Are the Biggest Challenges When Growing Redwoods?

Even with the right conditions, redwoods come with a set of common problems that catch people off guard.

• Root damage to structures: Shallow, aggressive roots crack foundations, lift patios, and invade sewer lines. This is the number one complaint from redwood owners.
• Summer water stress: A single missed watering during a heat wave can cause permanent tip dieback or weaken the tree to pests.
• Yellow needles and leaf drop: Usually a sign of alkaline soil, overwatering, or lack of nutrients. It can worsen into branch dieback if ignored.
• Pests: Redwoods are relatively pest-resistant, but spider mites and redwood bark beetles can attack stressed trees. Keep the tree healthy and well-watered, and pests rarely become a problem.
• Sunburn on young trees: Young redwoods have thin bark that burns in direct, intense sun. Provide partial shade for the first two to three years, or wrap the trunk with a light-colored tree wrap during summer.

One helpful tool for monitoring soil moisture is a soil moisture meter. Insert it near the root zone a few hours after watering. If the reading stays in the moist zone for more than a day, you are watering too much. If it drops to dry within a few hours, water more deeply.

Are There Legal Restrictions on Planting Redwoods?

In some areas, yes. If you live in a city or subdivision with a homeowners association, check local ordinances before planting. Some municipalities restrict planting tall or aggressive-rooted trees near property lines, sidewalks, or utility lines. In areas prone to wildfire, redwoods can be restricted because of their high resin content and tendency to create ladder fuels. In coastal California, some native redwood groves are protected, and planting non-native redwood species might be discouraged. Always call your local utility company to mark underground lines before you dig — a mistake here can cost thousands. If you own a small lot, some cities also require a permit for planting trees that exceed a certain mature height. Do your homework before the tree goes in the ground.

What Are Good Alternatives If You Cannot Plant a Full-Sized Redwood?

If you love the look of a redwood but your yard is too small or your climate is wrong, you have several alternatives that offer similar appeal without the massive size.

1. Bonsai redwood: You can grow a dwarf or bonsai redwood indoors or on a patio. These stay small by design and let you enjoy the species without the space commitment.
2. Dawn Redwood (Metasequoia glyptostroboides): This deciduous conifer looks similar to a redwood but drops its needles in fall. It grows fast but tops out around 70 to 100 feet, which is still large but more manageable than a Coast Redwood. It tolerates wet soil better and adapts to a wider climate range.
3. Japanese Cryptomeria (Cryptomeria japonica): A graceful evergreen conifer with soft, red-brown bark and a pyramidal shape. It reaches 50 to 60 feet at maturity and grows well in Zones 6 to 9. It handles humidity and moderate drought better than a true redwood.
4. Incense Cedar (Calocedrus decurrens): Native to California, this tree has a similar columnar shape and aromatic wood. It stays under 70 feet and tolerates drier conditions than redwoods.
5. Container planting: A young redwood can live in a large container for 5 to 10 years before it outgrows the pot. This gives you time to decide whether to plant it in the ground or keep it as a patio specimen. Make sure the container has drainage holes and use acidic potting mix.

Final Tips for Successfully Growing a Redwood Tree

Growing a redwood at home is a serious commitment, but with the right conditions it is absolutely achievable. The most important factors are space, acidic soil, consistent moisture, and matching the species to your climate. If your yard meets these requirements, a redwood can become a stunning, multi-generational feature of your property. If your space is limited or your soil is alkaline, consider a Dawn Redwood or a container tree instead. Use a drip irrigation system to automate watering for young trees, especially during the first three summers. Monitor your soil pH annually and adjust as needed. The best time to plant a redwood is in early fall or late winter, when the tree is dormant and the soil is workable. Give it room, keep it watered, and you really can grow a redwood — just make sure you are ready for a tree that will outlive you.
