Planting crepe myrtles is a fairly straightforward process with steps very similar to those used to plant nearly any tree or shrub. Those steps include choosing a proper location, preparing the site, placing the tree, and caring for the tree after planting. Depending on the size and circumstances, planting crepe myrtles can be an easy task that takes no longer than an hour or two. Some may also require extensive care after planting that includes consistent watering and fertilization.
One of the main reasons for planting crepe myrtles is to take advantage of the brilliant and bright colors that go along with blooming. In order for the tree to realize its full potential, the first step is choosing the proper location. The trees prefer sunny locations that are partially shaded at most. Therefore, making sure the tree stands away from other trees or structures can help, as well as planting it on a south-facing slope.
Closely related to where to plant a crepe myrtle, is when to plant the tree. Some times of the year are not conducive to planting crepe myrtles. Most are planted in the spring, but planting the tree anytime in the spring, summer, or early fall generally works. The trees prefer warmer temperatures, so they will need time to adjust to colder weather. Generally, a good rule of thumb is to make sure the tree is planted at least four weeks before the first frost, but the warmer the weather, the better the tree usually fares.
To plant the tree, dig a hole deep enough and wide enough to comfortably accommodate the tree's existing root system. String out the roots as much as possible in order to encourage the tree to take root quicker in the permanent placement. Fill the dirt back in over the tree, using plenty of water.
After planting crepe myrtles, watering becomes a very important step. While older, more established crepe myrtles are generally capable of sustaining mild droughts, new trees need more attention. They should be watered anywhere from one to five times a week, depending on the dryness of the soil and area. If the soil is dry to the touch, water is needed.
Another important consideration for young and newly-planted crepe myrtles is fertilizer. Older trees do not generally need a fertilizer, but in the first year after planting a slow-release fertilizer can help the tree become better established. The fertilizer should be relatively balanced, most likely either a 10-10-10 or 20-20-20 fertilizer. These provide equal amounts of nitrogen, phosphorous and potassium.
