5 Best Fertilizers For Crape Myrtles

Introduction to Plant Food

Crape myrtles are the best go-to plantation for most gardens and homeowners. At this moment there is no specific fertilizer that is meant for crape myrtles as the main purpose of fertilizers is to ready the soil for what is to come. 8-8-8, 10-10-10, 12-4-8 or 16-4-8 balance(s) of nitrogen, phosphorus, and potassium would work for crape myrtles. It’s important to understand that the Crape Myrtles flower doesn’t bloom from day one, it takes time.

Some Considerations to Bear in Mind

Crape myrtle requires greater amounts of nitrogen for a blooming flower at the end of the season. Also, the growth naturally occurs the best in the ideal season. and since the goal here is to get a blooming plant then it’s vital to not overdo the fertilization or the snipping of plants as that can ruin it. It all depends on the soil ph by the end of the day so make sure that you get the ideal fertilizer to get the best formula and soil ph. Be sure to keep a long-term approach instead of just being confined to short-term benefits. If your plants don’t bloom this time around, just prepare for the upcoming seasons.

Moreover, it is advisable to go for quick-release granular fertilizers as crape myrtle trees require fertilizing on and off. If you plan on not doing it that often then maybe a low nitrogen slow-release granule fertilizer might just be it so do your research. Bloom can occur only when there is new growth in spring and summer exclusively so it’s best to get things set up ahead of time.
