Factors Need to Consider While Choosing the Best Fertilizer for Crepe Myrtles:
Crepe Myrtles need adequate sunlight, PH in the soil, and large amounts of nitrogen and adequate fertilization, among other things, for fostering perfect growth. Let us now look at some of the major considerations to make before buying crape myrtle fertilizer.
Although Crape Myrtle requires very low maintenance, what they can’t do without is nitrogen. They need a large quality of nitrogen to produce the greatest number of flowers. So, we suggest that you choose an all-purpose garden fertilizer with 8-8-8 or 10-10-10 formulation.
This fertilizer formulation works better with big flowering trees like Crepe Myrtle. Besides, if applied at a lesser rate, 12-4-8 or 16-4-8 formulation can also be acceptable.
Check Soil pH
These trees will depend largely on the soil it is planted in. Therefore, consider a soil pH analysis before getting the fertilizer or planting the tree. Crepe Myrtles grow better on slightly more acidic soil, which ranges from 5.5 to 6.5 on the pH scale.
If the pH level of the soil is more or less than this range, consider buying fertilizer with more acidic content in it. Organic compost or compost mulch can also help maintain the acidic level of the soil.
Besides, you can add pelletized limestone to the soil if you want to raise the pH level. And if it needs lowering, apply some Aluminum Sulfate, Soil Sulfur, or Chelated Iron.
How to Properly Fertilize Your Crepe Myrtles?
Even with very low maintenance, Crepe Myrtles can blossom beautifully. But sometimes, feeding will make your plants look a lot better.
Crepe Myrtles will mostly do fine when fertilizers are applied above the soil. Sometimes, depending on the condition of the soil, you might have to use more or less of the plant food.
Granular products work best for these plants. When planting the tree, spread the granular fertilizer around the perimeter of the planting hole. Using just one teaspoon of it per small plant is enough, assuming they are planted from a one-gallon container.
You can increase or decrease this amount depending on the size of the plant. Repeat the process monthly. Make sure to water the plant well after applying the fertilizer. The best option is to apply it just after a rainfall.
If the plants are big enough and established, use one pound of 10-10-10 or 8-8-8 fertilizer per 100 square feet. But if the formulation is 12-4-8 or 16-4-8, then cut this amount into half.
When Should You Fertilize Crepe Myrtle?
The best timing to apply fertilizer to Crepe Myrtle is during the spring season when it starts to get new buds and is ready to bloom.
During Springtime, leaves in the trees start to appear, and they become heavy feeders. Apply fertilizer every month from spring to late summer, although some gardeners repeat this in the autumn too. This process will promote optimal growth in them.
Apply fertilizer less and less in the later fall. This process prepares the Crepe Myrtle to prepare for winter dormancy by tightening up the plant. As a result, it will be able to withstand the colder and drier conditions of the winter.
