Primary Nutrients (needed in higher quantities): Nitrogen (10%), Phosphorus (15%), Potassium (9%),
Secondary Nutrients (needed in moderate quantities): Magnesium (2%), Sulfur (9%) &
Macronutrients (needed in tiny quantities): Copper (0.05%), Iron (2.20%), Manganese (0.25%), Zinc (0.12%)
You see, the fertilizer displays an NPK ratio of 10-15-9. That means 100g of this fertilizer contains 10g N, 15g P & 9g K.
Now, let’s talk about Nitrogen. You know, Crape Myrtles require high Nitrogen, especially the tree cultivars like Muskogee, Natchez, Fantasy, Fauriei, etc. & for your concern, 10% N is pretty high. Moreover, there are five sources of N that provide 7.6% slow-releasing N for long-time feeding of Crape Myrtles.
In like manner, the fertilizer supplies a high amount of phosphorus to ensure ample Crape Myrtle blooms.
Though this fertilizer is ideal plant food for Crape Myrtles, it is well-received for Crab Apple, Crape Myrtle, Desert willow, Flowering Pear, Mexican Plum, Mimosa, Orchid, Texas Mountain Laurel, Viburnum & Vitex.
However, the most exclusive part is, it is a NUTRISTAR product. Nutristar is the Formula of Nelson Plant Food which guarantees improved blooming & stem strength. Additionally, it contains biosolids to enhance the soil quality organically.
For an inground single trunk Crape Myrtle tree of more than 12′ height, dig 1″ diameter holes of 6-12″ deep following the dripline. The distance between two holes should be 24″. Now, distribute 3 cups of the fertilizer evenly into the holes & water thoroughly.
2. Carl Pool Crepe Myrtle Plant Food
Carl Pool Crape Myrtle Plant food has an Amazon Best Seller tag. And that tells us, this fertilizer is a leading preference of gardeners for Crape Myrtle’s fertilization. Let’s see why it is so well accepted-
Though all the nutrients are obtained from safe inorganic sources, the nutrient composition is undeniably majestic for any flowering plant. The NPK ratio is 8-55-7. Along with N, P & K, the fertilizer provides five other essential micronutrients. And those are- Mg (0.50%), Cu (0.05%), Fe (0.18%), Mn (0.05%) & Zn (0.11%).
You know, phosphorus actively supports the energy transfer system of plants required for flowering & fruit setting. And that reveals the reason behind the massive phosphorus content of this fertilizer.
Moreover, it is a water-soluble Plant food to feed your Crape Myrtles instantly.
Though you may have to apply it weekly, I hope that’s not a problem as long as your Crape Myrtles show plentiful blooms.
I know, it’s a Crape Myrtle food, but guess what? Other flowering vines, trees & shrubs of your garden won’t mind either.
Interestingly, Cu, Fe, Mn & Zn are present in the chelated form to remain available for uptake & to avoid unnecessary harmful soil reactions for Crape Myrtles.
It is easy to use, just like watering. Mix 1 tablespoon of the fertilizer with 1 gallon of water & spray liberally over your potted dwarf Crape Myrtles, bushes, or trees. And to mention, one application remains effective for 7-10 days.

Interestingly, all these nutrients are taken from both organic & inorganic sources, such as polymer-coated urea, ammonium phosphate, ammonium sulfate, feather meal, kelp meal, alfalfa meal, earthworm casting, bone-meal, calcium carbonate & so on. And that’s how this unique blend makes it a semi-organic fertilizer.
The fertilizer provides 11% slow-release nitrogen obtained from polymer-coated urea & feather meal. And that’s why it is a continuous release fertilizer that feeds your Crape Myrtles for up to 3 months.
Its unique composition is specifically formulated for flowering trees, shrubs, and other acid-loving plants to secure deep, rich green foliage and vivid blooms throughout the season.
And additionally, the organic sources also add some other micronutrients like zinc, copper, iodine to help out your Crape Myrtles.
The most exclusive part is, the fertilizer includes natural components such as kelp, earthworm castings, feather meal & bone meal to feed the soil microbes. Soil microbes crackdown organic matter into nutrients that promote root strength and development that enhance water efficiency & increase flowering.
For in-ground Crape Myrtle trees, measure the diameter of the drip-line fast. For 4′ of diameter, apply 3 tablespoons of the fertilizer following the drip line & then water thoroughly.
4. Espoma Holly Tone Fertilizer
Espoma is a remarkable brand for organic gardening. Since 1929, the Espoma brand has released so many outstanding plant foods like Holly-Tone fertilizer. More details-
Feather meal, poultry manure, bone meal, alfalfa meal, greensand, sulfate of potash, sulfate of potash magnesia & elemental sulfur- these eight organic sources have contributed nutrients to the composition. However, the nutrient composition is-

The fertilizer contains Nitrogen of two available forms (NH4+, NO3-) for immediate feeding & 2.5% water-insoluble nitrogen for slow release & long-term feeding.
And though the company hasn’t declared the presence of any other nutrients, my research says it also adds some micronutrients like Fe, Na, Mn, etc.
Espoma Holly-Tone fertilizer guarantees better blooms & foliage for acid-loving plants like Crape Myrtles, Hydrangeas, Rhodos & many more.
But the fertilizer is widely welcomed for its exclusive BIO-TONE formula- a blend of beneficial biostimulants like bacteria & mycorrhizae. It ensures fast root establishment, stress tolerance & better blooms for Crape Myrtles.
Moreover, the fertilizer also preserves 1% humic acid to improve soil quality & nutrient uptake ability of Crape Myrtles.
With all these features, it is undisputedly the best organic fertilizer for Crape Myrtles.
For potted Crape Myrtles, spatter 4 tablespoons of Holly-tone for each 12″ of pot diameter into the soil along the outer end of the pot. And then, water thoroughly.
5. Scotts All Purpose Flower & Vegetable Continuous Release Plant Food
Crape Myrtles bloom throughout the whole summer & definitely a continuous-release fertilizer makes it easier to stay healthy & bloom abundantly during adverse summer. So, if you are looking for an all-purpose continuous release fertilizer, here you go-
It is a balanced fertilizer that means the NPK ratio is 10-10-10. And the nutrient sources are urea, polymer-coated sulfur-coated urea, potassium chloride & ammonium phosphate.
By the way, it also adds 2% sulfur to the soil.
The fertilizer supplies four very essential nutrients for crape Myrtles. If we talk about nitrogen, it is available in two forms to get uptaken easily. Moreover, 5.3% of nitrogen is slowly available for feeding for up to 2 months.
Conversely, the rest of the nitrogen & three other nutrients are released instantly for hungry Crape Myrtles.

6. Dr. Earth Organic Acid Fertilizer
“Our purpose is simple – to make the very best products that come from the best ingredients on earth”- Dr. Earth company explains its purpose like that. Quite promising, right? Let’s match this product’s quality with its promises-
The fertilizer obtained its nutrients from the best natural & organic sources like alfalfa meal, fishbone meal, feather meal, bone meal, potassium sulfate, kelp meal & kelp flour. And they also ensured 0% presence of filler & sludges to maintain the purity.
However, the product label says it supplies 3% N, 4% P & 3% K. But my further research says that the sources supply some other macro & micronutrients too.
You see, the fertilizer contains an equal amount of N & K but a higher amount of P. Well, as I said earlier, phosphorus works behind abundant blooming. So, that requirement is fulfilled. Moreover, available phosphorus feeds your Crape Myrtles immediately.
Now, Potassium also releases immediately & but all the nitrogen of this fertilizer is water-insoluble. You know, water-insoluble nutrients get available to uptake slowly than soluble ones. And that ensures a long-term nitrogen feeding for the gradual growth of your Crape Myrtles.
First of all, it is OMRI approved, so good news for organic gardeners. Secondly, it contains 11% Humic acid! Can you believe it? This high humic acid content would enhance the soil structure, soil drainage & nutrient holding capacity of your Crape Myrtles.
Thirdly, TruBiotic present. So, what is TruBiotic? It is a special blend of colony-forming soil microbes & Mycorrhizae to keep the soil fertile & improve gradually.
And fourthly, along with Crape Myrtles, you can apply it for other acid-loving plants like Hollies, Gardenias, Hydrangeas, etc.
So, tell me, isn’t it the perfect natural fertilizer for Crape Myrtles?
For potted Crape Myrtles, sprinkle evenly two tablespoons of fertilizer per gallon of potting soil. After light working on the soil, water thoroughly.
7. Down To Earth All Natural Acid Mix Fertilizer
Apart from their premium quality fertilizers, I like the idea of using the fertilizer packet as a paper mulch for recycling purposes. Anyway, let’s talk about the All Natural Acid Mix Fertilizer-
The fertilizer derived all its nutrients from prominent organic sources, such as cottonseed meal, fishbone meal, kelp meal, rock phosphate & langbeinite. And the nutrient composition is-
Primary Nutrients: N (4%), P (3%), K (6%) &
Secondary Nutrients: Ca (3%), Mg (2%), S (2%)
The fertilizer ensures both abundant blooming & vigorous growth. How? Let me explain-
0.4% of N & all other nutrients are instant releasers that mean Crape Myrtle could uptake them just after applying. But 3.6% N is water-insoluble & feeds your Crape Myrtle steadily for a long time. So, if you apply the fertilizer when the growth starts & apply again while bud shows up, you will get both abundant blooms & vigorous growth.
Ther fertilizer is suitable for all acid-loving plants like Crape Myrtles, Hydrangeas, Rhododendrons, Blueberries, Raspberries, etc.
And additionally, it contains 2.5% humic acid to make your Crape Myrtle’s feeding easier & to raise the soil quality.
Provide two tablespoons of acid mix per gallon of soil to your potted Crape Myrtles. After that, provide water thoroughly and relax for at least a month.
When To Fertilize Crape Myrtles?
The fertilizing thumb rule is, feed your plants throughout the first year & once set, fertilize only while actively growing.
You know, Crape Myrtles are summer bloomers & flowers only in new growth. And this new growth starts from early spring & ends with going dormant in late fall or winter.
So, when Crape Myrtles come up with new leaves & buds in early spring, they tell you to start fertilizing.

Soil’s nutrient status
