How to Care for Crape Myrtle Thunderstruck Lavender Blast

When purchasing your new Thunderstruck Lavender Blast Crape Myrtle Tree, be sure to read all the recommended care instructions so that your tree thrives in its new home.

How do I plant a Thunderstruck Lavender Blast Crape Myrtle Tree?

How do I plant a Thunderstruck Lavender Blast Crape Myrtle Tree?

Thunderstruck Lavender Blast Purple Crape Myrtles prefer full sun, so it is best to pick a spot where your tree can receive at least 6 to 8 hours of direct sun. Dig a hole in your garden that is 2 times wider and no deeper than its container. After placing your tree in the hole, fill the remaining space with a 50/50 mix of the soil you removed earlier and organic matter (such as topsoil and peat moss for nutrients and drainage), and pack down gently. Do not plant your tree too deeply and do not cover any of the multiple trunks with soil. Once this is complete, give your tree a good watering and cover the drip line with organic mulch.

How much sunlight does a Thunderstruck Crape Myrtle Need?

How much sunlight does a Thunderstruck Crape Myrtle Need?

Thunderstruck Lavender Crape Myrtles are generally considered to be very easy trees, low in maintenance and resistant to drought once established. However, the number one thing a crape myrtle tree like the Lavender Blast needs is full sun. Choose a location that will receive at least 7 to 8 hours of full sun exposure everyday. These trees are fairly heat tolerant and resistant to leaf scorch, so they are a good choice for creating shade for other smaller shrubs that cannot handle full sun.

Do I need to use mulch around my Crepe Myrtle Tree?

Do I need to use mulch around my Crepe Myrtle Tree?

Using an organic hardwood or cedar mulch will help your Thunderstruck crepe myrtle tremendously. Mulch will help regulate the temperature and moisture levels in the soil below, it will help prevent weeds from stealing nutrients nearby, and it can help add nutrients to the soil as the mulch breaks down. We recommend that you create a 2 to 3 inch layer of mulch around the tree, so that it covers the drip line under the branches but does not touch the trunks in the center. It is important to leave at least an inch gap between the mulch and the trunks to prevent root system rot and disease. Do not bury any of the trunks in too much mulch or soil.

How much water does a Thunderstruck Lavender Blast Crape Myrtle need?

How much water does a Thunderstruck Lavender Blast Crape Myrtle need?

Although fairly drought tolerant, the cold hardy Lavender Blast crape myrtle tree thrives in moist soil. Water young trees twice a week for up to a year until it is well established. After that, reduce your watering to once a week, depending on your local climate and recent weather. When in doubt, test the nearby soil and water if the top three inches are dry to the touch. We recommend watering for 5 seconds per gallon size of the nursery pot (at least while the tree is young). A 1 gallon pot needs 5 seconds from a typical garden hose, a 3 gallon pot needs 15 seconds, etc.
