The crape myrtle (Lagerstroemia indica), long beloved in Tucson for its dazzling summer flowers, is now available in a petite form that’s ideal for smaller yards, patios, and borders. The Crape Myrtle comes in many varieties, but this ‘petite’ option reaches only about 5 feet tall. Regardless of its smaller size, you’ll find it doesn’t sacrifice the brilliant bloom clusters that make crape myrtles so iconic. Cold hardy to 0°F and easy to maintain, this shrub brings weeks of summer color in pink, red, purple, or white depending on the variety. Whether mass-planted for impact or used as a single accent, the petite crape myrtle is a versatile, low-maintenance option for Arizona landscapes.
Planting
Indoor/Potted Planting Instructions
Petite crape myrtles adapt well to large containers, making them a great choice for patios or entryways. Choose a deep pot with drainage holes and use a high-quality, well-draining potting mix. Place the container in a location with full sun—at least 6 hours daily—for maximum blooms. Water thoroughly when the top 1–2 inches of soil dry out, and fertilize a bit more frequently than you would with in-ground plants since nutrients leach out faster in containers. Prune lightly to maintain shape and encourage airflow, but avoid heavy cutting.
Outdoor/Grounded Planting Instructions
For in-ground planting, select a sunny site with well-draining soil. Dig a hole twice as wide as the root ball but no deeper than the existing container depth. Place the plant carefully, backfill with native soil (amended lightly with compost if your soil is poor), and water thoroughly. Petite crape myrtles shine in groupings—plant them 4 to 6 feet apart when massing for a hedge or color block. For accents, one or two planted near patios, driveways, or entry paths can provide a strong focal point.
Watering
Consistent watering is the foundation of successful crape myrtle care. During the first year, water deeply once or twice per week depending on weather, ensuring the soil is moist down to the root zone. Deep, infrequent watering encourages stronger root growth compared to shallow, frequent watering. Once established, petite crape myrtles are fairly drought-tolerant but bloom best with supplemental watering during hot, dry Tucson summers. Always water at the base and avoid wetting the foliage, which can encourage fungal problems.
Fertilizing
Apply a balanced, slow-release fertilizer in early spring as new leaves begin to emerge. This jumpstarts growth and prepares the plant for its summer flower display. A second feeding in midsummer, especially after the first flush of blooms, can encourage a longer flowering season. For container-grown plants, use a diluted liquid fertilizer every 4–6 weeks during active growth. Avoid over-fertilizing, which may lead to excessive foliage growth with fewer flowers.
Growth Habits & Life Cycle
Petite crape myrtles form a dense, rounded shrub with multiple stems. Unlike standard crape myrtles that can grow into small trees, the petite variety tops out around 5 feet tall, making it well-suited for tight spaces. The highlight is the long-lasting summer bloom clusters, which can range from white to shades of pink, red, or purple. Flowering usually begins in late spring or early summer and can last for weeks, with the possibility of a second flush if spent blooms are removed. In autumn, the foliage sometimes takes on subtle shades of orange or red, adding seasonal interest. Though relatively slow to establish, these shrubs can live for decades with proper care.

Routine Maintenance
Petite crape myrtles require only light maintenance. In late winter or very early spring, prune to remove any dead, damaged, or crossing branches. Avoid heavy topping (sometimes called “crape murder”), which weakens plants and reduces flowering. During the season, deadhead spent flower clusters to encourage a second flush of blooms. Mulching around the base helps retain moisture and regulate soil temperature.
Care Tips
- Prune at the right time: Only prune in late winter or very early spring before new growth starts. Pruning too late may cut off flower buds.
- Encourage more blooms: Deadhead regularly after the first flush to promote additional flowering.
- Water deeply, not often: Shallow watering leads to weak roots; aim for less frequent but deeper soaks.
- Mulch wisely: Use a 2–3 inch layer of mulch around the base, but keep it a few inches away from the stems to prevent rot.
- Choose placement carefully: Full sun ensures the best flower display, while partial shade may reduce bloom count.
Propagation
Petite crape myrtles can be propagated through semi-hardwood cuttings taken in midsummer. Select a healthy, non-flowering stem about 6 inches long, strip the lower leaves, and plant in moist, well-draining soil. Keep in indirect light until roots form. Though slower, propagation by seed is possible, but seedlings may not grow true to the parent.
Pests and Problems
Crape myrtles are relatively trouble-free, but aphids are the most common pest. They cluster on new growth and can leave behind sticky honeydew. Spray with water or use insecticidal soap if infestations are heavy. Powdery mildew may occur in shady or poorly ventilated areas—choosing a sunny site and avoiding overhead watering prevents this. Other occasional issues include scale insects and leaf spot, though these are rarely serious with good cultural care.
