When it comes to fertilizing crape myrtles, a general-purpose garden fertilizer is your best bet. These fertilizers come in various formulations, such as 8-8-8, 10-10-10, 12-4-8, or 16-4-8. The three numbers in these formulations represent the percentage of nitrogen (N), phosphorus (P), and potassium (K) respectively.
Crape myrtles, like any other plants, require a balanced diet of nutrients to thrive. Nitrogen promotes leafy growth, phosphorus stimulates root development and flower production, while potassium enhances overall plant health and disease resistance. A general-purpose fertilizer with equal or balanced amounts of these three essential nutrients provides the necessary nourishment for crape myrtles.
I personally prefer using a 10-10-10 or 12-4-8 fertilizer for my crape myrtles. These formulations provide a balanced ratio of nutrients and are readily available at most garden centers or nurseries. It’s important to follow the instructions on the fertilizer packaging regarding application rates, as over-fertilizing can harm the plant.
When applying fertilizer to crape myrtles, it’s best to do so in early spring before new growth starts. This allows the plant to utilize the nutrients for the upcoming growing season. I typically sprinkle the fertilizer evenly around the base of the plant, taking care not to let it come into direct contact with the trunk or foliage. After applying the fertilizer, I lightly water the area to help the nutrients penetrate the soil.
In addition to using a general-purpose fertilizer, organic matter can also be beneficial for crape myrtles. Adding compost or well-rotted manure to the soil can improve its fertility and provide a slow-release source of nutrients. This can be done in conjunction with or as an alternative to chemical fertilizers.
It’s important to note that crape myrtles are generally low-maintenance plants and can still thrive without regular fertilization. However, by providing them with the right nutrients, you can encourage healthier growth, more abundant blooms, and increased resistance to pests and diseases.
To summarize, a complete general-purpose garden fertilizer, such as 8-8-8, 10-10-10, 12-4-8, or 16-4-8, is ideal for nourishing crape myrtles. Applying the fertilizer in early spring and incorporating organic matter into the soil can further enhance the plant’s health and performance. Remember to follow the instructions on the fertilizer packaging and avoid over-fertilizing.
