With brilliant summer blooms and foliage that creates fantastic fall colors, this tree is a must-have, year-round performer for those who love a little spectacle in their gardens and natural spaces.

How to Grow Crepe Myrtle
There are multiple ways to grow and propagate this plant. We suggest choosing the method you are most comfortable and familiar with as all of them can result in successful growth.
Most growers do tend to prefer buying a healthy plant from a reputable nursery and planting it where they want. Alternatively, the Crepe Myrtle can be propagated by seeds or by using cuttings.
Growing Crepe Myrtle from Seed
After flowering, crepe myrtles produce small, pea-sized berries that will eventually turn into seedpods. Once the seedpods have browned and started to split open, they can be used as seeds for sowing in spring.
These seedpods will ripen in the fall so you can collect and dry them for your sowing season.
Here is how to propagate using seeds:
- Using a pot or planting tray, gently place the seeds into your moist potting mix or composted soil. Cover lightly.
- If possible, place your pot or tray into a plastic grow bag for increased humidity control.
- Place your seeds in a warm, well-lit location with temperatures of around 75 degrees F.
- Germination can occur within 2 to 3 weeks.
Crepe Myrtle Propagation by Cuttings
Both softwood and hardwood cuttings can be used to propagate Crepe Myrtle. It is recommended to take cuttings during spring or summer when the cuttings meet the main branch.
Here is how to propagate using cuttings:
- Using a sharp tool, cut about 6 to 8 inches away with 3 to 4 nodes per cutting.
- Remove all the leaves other than the last 2 or 3.
- Dip each end of the cutting into some rooting hormone.
- Place the cuttings about 3 to 4 inches deep in a pot of moist sand and potting mix.
- Keep the cuttings in a warm and humid location where the soil is kept moist.
- Rooting can start to take place within 4 to 8 weeks.
Growing Lagerstroemia
Before planting your crepe myrtle, allow the germinated seedlings or rooted cuttings to acclimate further by moving them to their permanent locations in the current containers.
Thereafter, you can transplant and place them into their forever homes outside. Planting during late fall to early spring is recommended. Before picking the spot in your garden or on your property, here is what the crepe myrtle will need to grow and thrive:
What Soil to Use
These plants prefer neutral to acidic soils with a pH of around 6.0 to 6.5. They will also need moist soil that is well-drained to prevent the roots from standing in water.
Sunlight Needs
To ensure your crepe myrtle receives beautiful blooms with vivid color, make sure it receives full sun for at least 6 hours per day. Anything less will result in compromised blossoms. Pick out a good spot in your garden that experiences healthy sunlight.
Planting Crepe Myrtle
This is a relatively straightforward process and these trees don’t take too long to establish themselves. Before planting and after digging your hole, prepare the soil from the hole by mixing some compost into it.
To plant, follow these steps:
- Dig a large hole that is at least twice as wide as the root-ball and to the same depth the plant originally grew in.
- Gently remove the plant from its pot and tease the root-ball loose slightly.
- Place the plant in the planting hole where the topmost roots are almost at the soil line.
- Refill with your soil mixture and gently pat the dirt down.
- Water thoroughly for the first few days to help the roots settle in the soil and to remove any trapped air in the soil.
- Do not add fertilizer to the soil, this can be done at a later stage once the plant is established.
- For larger varieties, you can place a stake near the plant after planting for support while the roots establish themselves.
There should ideally be a 4-foot-wide area around your tree that is free of weeds or grass. This will ensure the tree receives enough water and nutrients.
Caring for Crepe Myrtle
Even though this species of lagerstroemia is tough and low maintenance, there are a few things you can do to ensure the blooms are luscious and that your tree or shrub thrives.
Once established, the crepe myrtle will be tolerant to drought and slightly resistant to mildew.
How to Water Lagerstroemia
This plant loves deep watering. That is why it is so important that the soil is well-drained because this will prevent root rot. It is recommended to water the plant with around two to three gallons of water per inch of trunk diameter.
After planting, you can water the plant thoroughly around once per week to help it establish itself. If you are experiencing dry conditions with little rainfall, you can increase watering to twice per week.
It is important to only water the roots of crepe myrtle. Try to avoid wetting the foliage when watering and this will help avoid the tree from contracting mildew issues.
Fertilizing Crepe Myrtle
Fertilizing this plant should be done on rare occasions. Overusing fertilizer can result in reduced flowering so only fertilize if you know your soil needs the boost. Fertilizing before rain is ideal.
Otherwise, you will need to water your plant after adding fertilizer. Use a general-purpose garden fertilizer such as 8-8-8, 10-10-10, or 12-4-8.
Mulch
During the warmer months of spring and summer, you can add 4 to 6 inches of mulch around your plant. Place the mulch a few inches away from the trunk to ensure good air circulation. It is recommended to use an acid mulch like pine bark or oak leaves for crepe myrtle.
How to Prune Crepe Myrtle
These plants bloom on new wood so pruning during late winter to early spring will encourage prolific blooming. If you are trying to establish your crepe myrtle as a tree, it is vital to prune all but one trunk off to establish a leader.
For a shrub form, pruning about a third of the plant away to keep shape during spring is recommended.
Crepe Murder
For growers who get a little too excited when pruning, try avoiding this common mistake. Many growers tend to prune the central branch of the tree away which means they essentially top the plant.
This can permanently ruin its growth and structure. Try just pruning foliage and other smaller branches to avoid this from happening to your plant baby.
Lagerstroemia Pests, Problems & Diseases
Fortunately, the lagerstroemia does not suffer from pest issues but they are susceptible to powdery mildew, sooty mold and other fungal issues.
To prevent these problems, don’t overwater your plant and water only the roots and not the foliage. For infected plants, a general fungicide can help.
In the case of small insects or aphids infesting the plant, treating it with insecticidal soap or neem oil can help.
