Where do crepe myrtles grow best?

Favorable conditions to thrive: It is normally cultivated in warmer climates around the world. The trees need plenty of sun to thrive (six or more hours per day), so choose the right sunny spot for this tree. Flowers will not be as productive with minimum sunlight or a partially shady location, and their colour may be diminished. These trees are adaptable to most soil conditions except those that are wet. The well-drained soil affords a wealth of summer flowers and helps keep pests away. The ideal soil pH is neutral to slightly acidic. The best time to plant crepe myrtle is early spring.

How big do crepe myrtles grow?

Description: These trees can grow up from 6 to 10 metres tall, but the dwarf and semi-dwarf varieties will grow between 2 to 6 metres tall. This makes the dwarf variety an ideal feature tree for the landscape design of smaller gardens. Crepe myrtle has dark green leaves with a reddish edge. In autumn, leaves change colour to red, yellow, or orange. The leaves are simple, oval in structure, and venation is pinnate. The bark is thin, light brown, and smooth.

Crepe myrtle normally grows at a medium to fast growth rate at about 30-60 cm per year. This means that they can also be used as a fast growing screening tree.

Crape myrtle (Lagerstroemia indica) is multi-stemmed, deciduous tree with a wide spreading, flat topped, rounded, or even spike shaped open habit. Planted in full sun or under canopy, the tree is a popular nesting shrub for songbirds and wrens.

Caring for your Lagerstroemia Indica

A new  plant requires at least 25mm of rainfall per week. If you are in sandy soil or a very hot regions, water  twice a week. Water the new plant regularly for about two months. The mature crepe myrtle is drought resistant. However, if you want better flowers and healthier plants, then watering is better.

Arborist and horticulturists are divided about the pruning of crepe myrtle. However, pruning crepe myrtle in late winter is the probably the best option. Remove any branches that cross or crowd the centre, even those that are unhealthy or dead. Avoid excessive trimming since it has its own drawbacks. Severe pruning produces knobby growth that is more susceptible to disease. If you want a tree with a single trunk, remove any lateral branches that may compete with the leader. Trees having several trunks should be pruned to maintain their shape and avoid crowding or contacting one another.

Problems with Crepe myrtle

These are relatively robust, trouble-free trees that are resistant to most garden tree problems.  However, it might be susceptible to fungal diseases such as leaf spots and powdery mildew. These problems can easily be treated with organic pesticides. Additionally, many new cultivars are bred, resistant to this fungal disease. Look for hybrids between the L.indica and the L.fauriei species that are more resistant to fungal diseases.

Use a single specimen as a focal point. Because many other flowering trees are simply green leaves, crepe myrtle makes a colourful centrepiece to the lawn throughout summer. They are beneficial for planting among smaller flowering shrubs since they will offer a mix of colours when flowers appear. Some of the larger varieties of crepe myrtle look wonderful when planted in sunny areas before a full-sized shade tree. Use dwarf varieties as a colourful addition to borders and beds. Plant medium-sized crepe myrtle together to form a deciduous hedge.
