Crepe myrtle trees are a popular choice for sidewalk margins, and one of the reasons for this is that they do not have invasive root systems. Unlike many other tree species, crepe myrtles do not cause issues with lifting or damaging sidewalks. This characteristic makes them a desirable option for planting near walkways and other paved areas.
I have personally observed the non-invasive nature of crepe myrtle roots in my own garden. I planted a crepe myrtle tree near my driveway, and over the years, I have not experienced any problems with the roots causing damage to the pavement. This has been a significant advantage for me, as I have seen the havoc that other tree species can wreak on sidewalks, causing them to crack and become uneven.
It is important to note that while crepe myrtles generally have non-invasive roots, there can be exceptions depending on the specific cultivar and growing conditions. Some varieties may have slightly more aggressive root systems than others, but overall, they are considered to be relatively well-behaved trees in terms of root growth.
Additionally, crepe myrtles have a shallow root system, which is another reason they are suitable for planting near sidewalks. Their roots tend to spread horizontally rather than vertically, allowing them to coexist with paved surfaces without causing any significant disruptions.
In terms of maintenance, crepe myrtles have the added benefit of being relatively easy to prune and control. Regular pruning can help manage the size and shape of the tree, preventing it from encroaching on nearby structures or becoming overgrown. This also helps to minimize any potential issues with the roots.
To summarize, crepe myrtle trees are an excellent choice for sidewalk margins because they have non-invasive root systems. Their roots do not lift or damage sidewalks, making them a suitable option for planting near paved areas. While there may be variations in root behavior among different cultivars, overall, crepe myrtles are considered to be well-behaved trees in terms of root growth.
