Planting two crape myrtles together is one of the most common moves in warm-climate landscaping, and it works beautifully when you get the spacing right. Whether you're framing a front entry, lining a driveway, or building a summer-blooming privacy screen, the pairing creates symmetry and seasonal color that's hard to beat. The catch is that "together" means different things depending on the variety you choose and the look you're after.
The key variable is mature spread. A standard crape myrtle (Lagerstroemia indica) can reach 15 to 25 feet wide at the canopy, while semi-dwarf and dwarf cultivars stay far more compact. Get the spacing wrong and you'll either end up with a crowded, disease-prone mess or a pair of lonely trees with a gap between them that never closes.
Let's walk through how to figure out the right setup for your yard.
Quick Answer: Yes — But Spacing Depends on Your Goal and Variety
Planting two crape myrtles together works well for hedges, entryway accents, and privacy screens. Standard varieties need 10 to 15 feet between centers. Semi-dwarf types do best at 6 to 10 feet apart.
Dwarf cultivars can go as close as 3 to 5 feet. Always plan for the mature canopy spread, not the size of the nursery container.
What Happens When You Plant Two Crape Myrtles Close Together
Crape myrtles are forgiving trees, but they're not immune to the problems that come from poor spacing. When two trees are planted too close, their canopies overlap as they mature. That overlap blocks airflow through the crown, and trapped moisture is the number one trigger for powdery mildew, the white fungal coating that plagues many crape myrtle varieties.
Root competition is another issue. Crape myrtles develop wide, fibrous root systems that spread well beyond the drip line. When two root zones compete for water and nutrients in a tight footprint, both trees can show reduced flowering, slower growth, and increased stress during drought.
You'll notice thinner bloom clusters and more leaf drop in mid-summer.
On the flip side, planting too far apart creates its own problems. If you're going for a hedge or a paired visual statement, excessive spacing leaves a gap that may never fill in. The trees grow as two isolated specimens instead of a unified feature, which defeats the purpose of planting a pair in the first place.
The sweet spot is spacing that lets each tree reach close to its natural canopy width without significant overlap. That gives you full, healthy crowns, good air circulation, and the visual density most homeowners are looking for.
How to Choose the Right Spacing for Your Crape Myrtles
Spacing isn't one-size-fits-all. It depends on which type of crape myrtle you're planting and what you want the finished result to look like. Here's how the three main size categories break down.
Standard Varieties (15–25 ft mature spread)
Standard crape myrtles like 'Natchez' (white), 'Muskogee' (lavender), and 'Tuscarora' (coral pink) are the large, tree-form cultivars that can reach 20 to 25 feet tall and just as wide. These need the most room.
For a paired planting, space standard varieties 10 to 15 feet apart, center to center. That gives each tree enough room to develop a full canopy while still creating a connected look at maturity. If you're flanking a driveway or entry, measure from the center of each planting hole to the nearest hard surface as well.
You'll want at least 8 feet of clearance from a driveway edge to avoid root damage and canopy overhang as the tree grows.
Standard varieties work best as standalone pairs rather than tight hedges. If you want a denser screen, semi-dwarf types are a better fit.
Semi-Dwarf Varieties (8–12 ft mature spread)
Semi-dwarf cultivars like 'Catawba' (dark pink), 'Sioux' (medium pink), and 'Acoma' (white, weeping form) top out around 8 to 12 feet tall and wide. They're the most versatile option for paired planting because they're large enough to make an impact but compact enough to work in most residential landscapes.
Space semi-dwarf crape myrtles 6 to 10 feet apart. At the tighter end (6 feet), they'll form a dense, interlocking canopy within a few years. At 8 to 10 feet, they'll maintain a more open, individual-tree look while still reading as a pair.
This is the category most homeowners should start with if they're unsure. Semi-dwarfs handle a wider range of spacing without looking awkward, and they're less prone to the overcrowding problems that standard varieties develop in tight quarters.
Dwarf Varieties (3–6 ft mature spread)
Dwarf crape myrtles like 'Pocomoke' (deep pink), 'Chickasaw' (lavender-pink), and 'Victor' (red) stay under 6 feet tall. They're technically large shrubs, but they're often sold and planted as small accent trees.
For dwarf varieties, 3 to 5 feet of spacing is plenty. At that distance, two plants will form a dense, low mass of foliage and flowers that works well as a foundation planting, a low hedge, or a border accent. Dwarfs are also the best choice if you're working with a small urban lot or planting near a patio where a full-size tree would overwhelm the space.
One thing to watch: dwarf crape myrtles bloom heavily but have thinner, more delicate branches. Planting them too close (under 3 feet) can make the interior of the pair look twiggy and sparse because light can't reach the inner stems.
Step-by-Step: How to Plant Two Crape Myrtles Together
Once you've picked your variety and figured out the spacing, the planting process itself is straightforward. Here's the full sequence.
Step 1: Pick the Right Variety for Your Space
Before you dig anything, match the variety to your site conditions and design goal. Check the mature height and spread listed on the nursery tag or the grower's documentation. If you're in USDA Zone 6 or the colder edge of Zone 7, stick with cold-hardy hybrids like those in the US National Arboretum's Indian Tribe series (labeled by color, like 'Arapaho' or 'Zuni').
These have better bark hardiness and flower reliably in shorter seasons.
Also consider bloom color and form. Multi-trunk specimens give a fuller, shrubbier look that works well in pairs. Single-trunk standards read more like formal trees.
Both work, but the visual effect is different.
Step 2: Measure and Mark Your Spacing
Use a tape measure and two stakes or marking flags to set the exact center points of each planting hole. Measure center to center using the spacing guidelines above. Then step back and look at the layout from the angle you'll see it most often, usually from the street or the front door.
Check for overhead obstructions like power lines or eaves. Standard crape myrtles can eventually reach 20-plus feet, and you don't want to plant a tree that will grow into a utility line. Also call 811 (the national "call before you dig" service) to have underground utilities marked.
This is free and required by law in most states.
Step 3: Dig the Planting Holes
Dig each hole two to three times wider than the root ball and exactly as deep as the root ball height. This is where a lot of people go wrong. A hole that's too deep settles the tree too low, and the root flare ends up below grade.
That leads to root rot and poor establishment.
If your soil is heavy clay, score the sides of the hole with a shovel so roots can penetrate outward. If drainage is a concern, you can read more about how soil conditions affect root development in our guide on how deep are bermuda grass roots, which covers the relationship between soil structure and root zone health.
Don't amend the backfill heavily. Research from NC State Extension shows that trees establish better when the backfill is native soil rather than a heavily enriched mix. The goal is to get roots growing outward into the surrounding ground, not circling in a pocket of perfect potting mix.
Step 4: Set the Trees and Backfill
Remove the tree from the container and gently loosen any circling roots. Place the root ball in the hole so the root flare (where the trunk widens at the base) sits at or slightly above the surrounding soil level. Backfill with native soil, tamping lightly to eliminate air pockets but not compacting heavily.
Water the hole halfway through backfill and again after you're done. This settles the soil around the root ball and ensures good contact. If you're planting on a slope, build a small berm on the downhill side to hold water.
Step 5: Water Deeply and Mulch
Give each tree a slow, deep soaking immediately after planting. A soaker hose or a garden hose on a trickle left at the base for 30 to 60 minutes works well. The goal is to saturate the entire root zone, not just the surface.
Apply 2 to 3 inches of organic mulch (shredded bark, pine straw, or wood chips) in a wide ring around each tree. Keep the mulch pulled back 3 to 4 inches from the trunk. Mulch piled against the trunk traps moisture and invites fungal problems, which is the last thing you want on a newly planted crape myrtle.
For the first growing season, water weekly with a deep soak if rainfall is less than 1 inch per week. Crape myrtles are drought-tolerant once established, but new plantings need consistent moisture to develop a strong root system.
Best Planting Patterns for Two Crape Myrtles Together
How you arrange the pair matters as much as the spacing. Here are the three most common configurations and when each one works best.
Symmetrical Flanking (Driveways, Entryways)
This is the classic "two trees on either side" look. Plant one crape myrtle on each side of a driveway entrance, front walk, or gate, spaced equally from the center line. Standard or semi-dwarf varieties work best here because you want enough height and canopy to create a sense of arrival.
Aim for at least 8 feet of clearance from the edge of a driveway to the trunk center. Crape myrtle roots are generally not aggressive enough to crack pavement, but the canopy will overhang, and you want room for car doors and foot traffic.
This pattern works especially well with matching varieties. Two 'Natchez' crape myrtles (white flowers, exfoliating cinnamon bark) flanking a front walk is one of the most recognizable Southern landscape combinations for good reason. The symmetry is clean, the summer bloom is showy, and the winter bark interest carries the look through the off-season.
Hedge or Privacy Pair
If you want two crape myrtles to function as a semi-formal screen, plant them closer together, at the low end of the spacing range for your variety. Semi-dwarf types at 6 feet apart will form a connected canopy within three to four growing seasons.
This isn't a true hedge in the boxwood sense. Crape myrtles are deciduous (or semi-evergreen in the warmest zones), so you'll lose the screen effect in winter. But during the growing season, a tight pair of semi-dwarfs creates a dense wall of foliage and flowers that blocks sight lines and adds privacy to a patio or side yard.
For year-round screening, you might pair crape myrtles with an evergreen shrub behind or between them. That gives you summer color from the crape myrtles and winter structure from the evergreens.
Informal Garden Pairing
Not every planting needs to be symmetrical. Two crape myrtles placed at slightly different distances from a path or focal point can create a natural, relaxed look that works well in cottage-style or pollinator gardens. This approach gives you more flexibility with spacing.
You can tuck one tree closer to a seating area and let the other sit further back as a backdrop.
Dwarf and semi-dwarf varieties shine in this configuration. Their smaller scale keeps the pairing from overwhelming a mixed border, and their long bloom season (often 90 to 120 days in warm climates) provides consistent color from early summer through fall.
If you're building a pollinator-friendly space, crape myrtles attract bees and butterflies in abundance. Pair them with other warm-season bloomers like lantana, salvia, or native grasses for a low-maintenance, high-impact garden bed.
Common Mistakes When Planting Two Crape Myrtles Together
Even experienced gardeners make these errors. Here's what to watch for.
Planting too close based on nursery size. A 3-gallon crape myrtle in a pot might only be 2 feet wide. Its mature spread could be 12 feet or more. Always plan for the full-grown dimensions, not what you see at the garden center.
Ignoring air circulation. Tight spacing without regard for airflow sets up powdery mildew, especially on older Lagerstroemia indica varieties. If you're in a humid climate, choose mildew-resistant cultivars like those in the US National Arboretum's series and give them the full recommended spacing.
Planting too deep. The root flare should be visible at or above soil level. Burying it invites stem rot and weakens the tree's anchor over time.
Over-pruning to manage size. When two crape myrtles start crowding each other, the instinct is to cut them back hard. That leads to "crape murder," the aggressive topping practice that ruins the tree's natural form and produces weak, knobby growth. If the trees are too close, it's better to remove one than to butcher both.
Skipping the first-year watering schedule. New crape myrtles need consistent moisture for at least one full growing season. Letting them dry out repeatedly in year one stunts root development and can delay blooming by a full year.
Forgetting about winter interest. Crape myrtles are often chosen for summer flowers, but the exfoliating bark on varieties like 'Natchez' and 'Muskogee' provides texture and color in winter. When you're planning a paired planting, think about how the trees will look in January, not just July.
How Crape Myrtles Grow Over Time — What to Expect by Year
Understanding the growth timeline helps you set realistic expectations. Here's a general progression for a properly spaced pair.
Year 1: Establishment phase. The trees focus energy on root growth above ground. You may get a few blooms, but don't expect much.
Growth above ground is slow, maybe 6 to 12 inches. Keep up the weekly watering and don't fertilize heavily. A light application of a balanced slow-release fertilizer in spring is enough.
Year 2: Visible growth kicks in. Expect 1 to 2 feet of new growth and a noticeable increase in bloom production. The canopy starts to take shape.
This is when you'll see whether your spacing is working. If the canopies are already touching, they're too close.
Year 3 to 5: Rapid growth phase. Standard varieties can put on 2 to 3 feet per year in good conditions. Semi-dwarfs add 1 to 2 feet annually.
The trees begin to fill out and develop their characteristic form. By year five, a well-spaced pair of semi-dwarfs will be creating meaningful canopy overlap if that's what you planned for.
Year 5 to 10: Maturity approaches. Standard varieties are approaching their full height and spread. Bloom production peaks.
This is also when maintenance pruning becomes important. Remove any crossing or inward-growing branches to maintain airflow through the canopy.
Year 10 and beyond: Full maturity. Standard crape myrtles can live 50 years or more with proper care. The bark becomes more exfoliated and ornamental with age.
At this point, the pair should look like a cohesive, well-established landscape feature.
Crape Myrtles vs. Other Paired Planting Options
Crape myrtles aren't the only option for a two-tree planting. Here's how they stack up against common alternatives.
| Feature | Crape Myrtle | Viburnum | Hydrangea | Redbud |
|---|---|---|---|---|
| Mature height | 6–25 ft (variety dependent) | 6–12 ft | 3–6 ft | 20–30 ft |
| Bloom season | Summer (60–120 days) | Spring | Summer | Early spring |
| Winter interest | Exfoliating bark | Some evergreen types | Minimal | Minimal |
| Drought tolerance | High (once established) | Moderate | Low to moderate | Moderate |
| Best for | Warm climates, full sun | Partial shade, mixed borders | Shade gardens, accent | Understory, naturalized |
Crape myrtles win in hot, sunny sites where other plants struggle. They outperform hydrangeas in drought conditions and offer a much longer bloom season than redbud. For USDA Zones 7 through 10, they're one of the most reliable summer-blooming trees you can plant.
If you're in a cooler climate (Zone 5 or 6), redbud or viburnum may be a better fit. And if your site is shaded, crape myrtles won't flower well regardless of spacing. They need at least 6 hours of direct sun to bloom reliably.
Expert Tips for Healthy, Well-Spaced Crape Myrtles
A few things that separate a good crape myrtle planting from a great one.
Choose mildew-resistant varieties. The US National Arbretum's Indian Tribe series and the Lagerstroemia × fauriei hybrids (like 'Biloxi' and 'Fantasy') have significantly better powdery mildew resistance than older Lagerstroemia indica cultivars. If you're in the humid Southeast, this matters.
Prune in late winter. February or early March, before new growth starts, is the ideal window. Remove dead wood, crossing branches, and any suckers from the base. Keep the canopy open in the center for airflow.
Don't over-fertilize. Crape myrtles don't need much. Too much nitrogen pushes leaf growth at the expense of flowers and makes the tree more susceptible to mildew. One light application of a balanced fertilizer in early spring is sufficient for established trees.
Monitor for scale insects. Crape myrtle bark scale (CMBS) has become a significant pest in parts of the Southeast and Texas as of 2026. Look for black sooty mold on the bark and white felt-like masses on twigs. Early treatment with horticultural oil or systemic insecticide prevents serious infestations.
Think about the root zone when planning nearby plantings. Crape myrtles have shallow, spreading roots that compete aggressively with turf and groundcovers. If you're establishing a lawn near a new crape myrtle planting, give the trees a generous mulched bed rather than trying to grow grass right up to the trunk. Our guide on how to get bermuda grass to spread covers root competition dynamics that apply here too.
When to Call in a Pro
Most homeowners can handle a two-tree crape myrtle planting on their own. But there are situations where professional help is worth the cost.
If you're planting large standard varieties (15-gallon containers or bigger), the root balls are heavy and awkward. A landscape crew with a tree dolly and experience setting large specimens can do in an hour what might take a full weekend for a DIYer.
If your site has drainage issues, a landscape architect can assess whether raised beds or amended soil profiles are needed before planting. Crape myrtles tolerate a wide range of soil types but will not survive in standing water.
And if you're dealing with an existing pair that's grown too close together, an arborist can advise on whether to remove one tree or attempt a careful root-pruning and canopy management strategy. Removing a mature crape myrtle is a significant decision, and a professional assessment helps you avoid regretting it later.
Frequently Asked Questions
How far apart should I plant two crape myrtles?
It depends on the variety. Standard types need 10 to 15 feet, semi-dwarfs need 6 to 10 feet, and dwarfs need 3 to 5 feet. Always plan for the mature canopy spread, not the size of the tree at planting time.
Can I plant two crape myrtles in the same hole?
No. Each tree needs its own planting hole with enough room for the root ball and surrounding soil. Sharing a hole concentrates root competition and leads to poor establishment for both trees.
What is the best time of year to plant crape myrtles?
Fall is ideal in warm climates (Zones 7, 10). The tree gets a full cool season to establish roots before summer heat arrives. In Zone 6, spring planting after the last frost gives the tree the best chance of surviving its first winter.
Will two crape myrtles block a view or create privacy?
Semi-dwarf varieties planted 6 feet apart will form a connected canopy within a few years that provides moderate visual screening during the growing season. For year-round privacy, supplement with evergreen shrubs.
Do crape myrtles have invasive roots?
No. Crape myrtles have fibrous, spreading root systems but are not considered invasive or aggressive toward foundations, sidewalks, or plumbing. Standard spacing from hardscape (8 feet minimum) is still recommended to allow for canopy growth.
How long before my crape myrtles bloom after planting?
Most crape myrtles bloom lightly in the first year and more heavily by year two. Full bloom production typically kicks in by year three, assuming the trees are getting enough sun and water.
Maintenance and Long-Term Optimization
Once your pair is established, crape myrtles are remarkably low-maintenance. But "low-maintenance" doesn't mean "no-maintenance." A little seasonal attention keeps both trees healthy and looking their best for decades.
Annual pruning is the single most important task. Late February through mid-March is the window. Remove any dead or damaged wood first.
Then thin the canopy by cutting back inward-growing branches to their point of origin. The goal is an open, vase-shaped crown that lets light and air move through. Avoid cutting back the main trunks to stubs.
That practice, common in some municipal plantings, weakens the tree and produces dense clusters of weak new growth that snap in wind.
Fertilization should be minimal after year two. A single application of a balanced slow-release fertilizer (10-10-10 or similar) in early spring is enough. If your soil is already fertile, you can skip it entirely.
Over-fertilizing leads to excessive leaf growth, fewer blooms, and increased susceptibility to powdery mildew.
Mulch maintenance matters more than most people realize. Refresh the mulch ring annually, keeping it at 2 to 3 inches deep and pulled back from the trunk. As the trees mature, expand the mulched area to cover the full drip line.
This reduces competition from turf grass, which is especially important if you're growing a lawn nearby. Our guide on what is the best fertilizer for bermuda grass covers how aggressive warm-season turf can be at competing for nutrients in the root zone.
Pest monitoring should be part of your routine. Crape myrtle bark scale has spread significantly across the southern US as of 2026. Check the trunks and major branches in spring for white or gray felt-like patches.
If you spot them, treat with horticultural oil during the dormant season or a systemic insecticide labeled for scale. Early intervention prevents the black sooty mold that follows heavy infestations.
Watering after establishment is mostly unnecessary in areas that get regular rainfall. During extended droughts (three or more weeks without rain), give each tree a deep soak. Established crape myrtles are among the most drought-tolerant ornamental trees once their root systems are fully developed, usually by year three.
Real Scenarios: What Works and What Doesn't
Here are three common situations homeowners face when planting two crape myrtles together, and what the research and field experience suggest.
Scenario 1: A 20-foot-wide front yard bed. You've got a narrow planting strip between the sidewalk and the front wall. A standard crape myrtle is too big. Two semi-dwarf varieties like 'Sioux' spaced 8 feet apart will fill the space without crowding the foundation.
Dwarf varieties would leave too much empty bed.
Scenario 2: Flanking a 12-foot-wide driveway. Two standard 'Natchez' crape myrtles planted 12 feet apart (6 feet from the driveway edge to each trunk center) create a classic Southern entry look. The canopies will nearly touch at maturity, forming a partial canopy over the drive. Make sure you've got at least 14 feet of vertical clearance overhead.
Scenario 3: A small patio privacy screen in Zone 7. Two semi-dwarf 'Acoma' crape myrtles (white, weeping form) planted 7 feet apart will create a dense, flowering screen by year four. 'Acoma' is cold-hardy to Zone 6, so it handles Zone 7 winters without issue. The weeping habit gives a softer look than upright varieties, which works well near seating areas.
In each case, the variety choice and spacing work together. Change one variable and the whole plan shifts. That's why it's worth sketching out the mature dimensions on paper before you buy.
Final Recommendation: The Right Spacing for Your Situation
If you're planting two crape myrtles together and want a quick starting point, here's the decision framework.
For a formal entry or driveway pair: Go with standard varieties at 12 to 15 feet apart. You'll get a grand, symmetrical look with full-size canopies. Best for properties with room to spare.
For a residential front yard or side yard: Semi-dwarf varieties at 6 to 8 feet apart hit the sweet spot. Enough space for healthy growth, enough overlap for a unified look. This is the most versatile configuration for typical suburban lots.
For a small space or foundation planting: Dwarf varieties at 3 to 5 feet apart. Compact, manageable, and still showy in bloom. Ideal for courtyards, patios, and tight urban yards.
For a hedge effect: Semi-dwarf varieties at the tightest end of their range (5 to 6 feet). They'll knit together within a few years and create a living wall of summer color. Just commit to annual pruning to keep the interior from getting too dense.
Whatever you choose, remember that the tree you plant today will be two to three times wider in five years. Plan for the mature size, not the nursery size. That single habit is the difference between a planting that looks intentional for decades and one that becomes a crowding problem by year three.
