Crepe myrtles with their stunning summer blooms and iconic silhouettes, bring a unique charm to the landscapes of Baton Rouge and New Orleans. These beloved trees, known for their striking colors and extended blooming season, require specific care during the winter months to ensure they thrive come spring and summer. Here’s how Baton Rouge and New Orleans homeowners can keep their crepe myrtles looking healthy and vibrant year after year.

Winter Pruning for Shape and Health

As the winter months approach, crepe myrtles enter a dormant phase. This is the ideal time to focus on pruning, a critical step in promoting healthy growth and enhancing the tree’s natural shape. By removing old, dead, or overcrowded branches, more sunlight can reach the interior of the tree, allowing for fuller, more vibrant blooms in the summer. Pruning also helps prevent common issues like pest infestations, as it improves airflow and reduces dense areas where pests and diseases can hide.

Bayou Tree Service’s team of certified arborists is skilled in precision pruning techniques, which are especially important for delicate trees like crepe myrtles. Our approach ensures that each cut enhances the tree’s structure without over-pruning, a mistake that can weaken the tree. We understand that Baton Rouge and New Orleans’ climates require tailored care, especially during the colder months, to support trees in the upcoming growing season.

Inspecting for Pests and Diseases, Including Crepe Myrtle Bark Scale

In the warm, humid climates of New Orleans and Baton Rouge, crepe myrtles are susceptible to pests and diseases, including a particularly troublesome pest: crepe myrtle bark scale. This invasive pest appears as small, white or grayish bumps along the tree’s bark, often accompanied by a black, sooty mold that grows on the honeydew the scales produce. Left untreated, crepe myrtle bark scale can weaken the tree, reduce bloom production, and leave it vulnerable to other pests and diseases.

Winter is an ideal time to inspect your trees for early signs of crepe myrtle bark scale, along with other common issues like aphids and powdery mildew. Addressing these issues while the tree is dormant can help prevent them from spreading in warmer months. Dormant-season treatments, such as horticultural oils, are often effective at reducing scale populations and managing other pests. By taking action now, you’re supporting a healthier tree that will thrive come spring and summer.

Mulching to Protect Roots and Conserve Moisture

In addition to pruning and pest management, adding a layer of mulch around the base of your crepe myrtles can help protect the roots from winter cold and conserve moisture. Organic mulch, like shredded bark or wood chips, not only insulates the soil but also slowly enriches it as it decomposes. Aim to create a mulch ring around the base, leaving some space around the trunk to avoid trapping moisture against the bark. This simple step can go a long way in supporting your tree’s health through winter’s chilly nights and fluctuating temperatures.

Year-Round Care for Healthy Blooms

Crepe myrtles are an iconic part of Baton Rouge and New Orleans landscapes, and their beauty depends on consistent care throughout the year. Winter pruning and maintenance set the stage for a healthier, more vibrant tree, but they’re only part of a comprehensive tree care approach. By keeping an eye on soil health, providing adequate water during dry periods, and scheduling regular professional inspections, homeowners can ensure their crepe myrtles thrive in all seasons.

I manage the commercial construction bidding process and coordinate Bayou Tree Service’s marketing efforts, including social media and brand direction. On any given day, that means keeping projects organized, helping tell our story, and making sure the Bayou boys stay (mostly) on track. Bayou Tree Service has been part of my life since I was 16, when I started working here during summers and school breaks. Even after earning my master’s degree in Clinical Mental Health, I found myself missing the work we do here and the people behind it. Coming back felt natural—this work matters, and being part of it always felt bigger than just a job. I earned my arborist license because I wanted to truly understand what I was writing about and be able to have informed conversations with the arborists in the field. I care deeply about our community and the role we play in preserving the urban canopy, and I take pride in helping share that responsibility through our work. Being part of Bayou Tree Service’s 45-year history means being part of a family—one that values hard work, trust, and doing right by the trees and the people we serve. I’m proud to be part of a company that feels like home and to support work that has lasting impact.
