Crepe Myrtle Plant Food — Water Soluble 24oz 8-55-7
Best for: gardeners who prefer quick-acting, root-and-leaf feeding. This water-soluble formula feeds through both roots and leaves, delivering nitrogen, phosphate, and potash as an 8-55-7 ratio. Suitable for established crepe myrtles and new plantings alike, it supports vigorous foliage and rapid uptake after applications. Consider this option when you want flexibility to mix with water for immediate use.
Why selected: The product advertises fast results and dual-path feeding, which can help trees recover after pruning or stress periods. It’s easy to dissolve in irrigation or a watering can, making it convenient for busy households.
Caution: Ensure uniform dissolution to avoid concentrated spots that can cause leaf burn in extreme conditions. Follow label directions for frequency and dilution to minimize risk.

Crape Myrtle & All Flowering Trees NutriStar Granular Fertilizer (4 lb.)
Best for: gardeners preferring granular fertilizer that feeds flowering trees including crepe myrtle and other ornamentals. This product is a multi-tree formula designed for both in-ground and container plants. It’s especially suitable for established landscapes needing a long-lasting nutrient supply.
Why selected: Granular formats offer flexible timing—top-dress or incorporate into soil during planting or seasonal feeding. The NutriStar line emphasizes a broad mineral mix to support bloom quantity and overall vigor.
Caution: Expect a slower initial response than liquids; results vary with soil conditions and irrigation. Avoid applying to recently transplanted wood or during extreme heat without following label guidance.
Crepe Myrtle Fertilizer – Liquid Plant Food (1 Gallon)
Best for: larger crepe myrtles or gardens needing a higher volume of liquid fertilizer for extended feeding periods. The one-gallon size supports heavier application schedules and larger landscapes where multiple trees are present.
Why selected: This option mirrors the 8 oz liquid product’s benefits while offering more quantity for ongoing maintenance. It helps maintain consistent nutrient availability during active growing seasons.
Caution: Follow dilution rates closely to prevent leaf burn or over-fertilization in spring, especially in regions with intense sun or high temperatures.

Buying Guide
What form should I choose: liquid or granular?
Liquid formulas are typically faster-acting and easier to apply with watering cans or hose-end applicators. Granular fertilizers offer longer-lasting feed and can be practical for larger landscapes where frequent mixing is inconvenient. Consider your routine, landscape size, and whether you prefer seasonal top-dressings or regular liquid applications.
Is one fertilizer better for container crepe myrtles?
Container-grown crepe myrtles benefit from balanced water-soluble or liquid feeds that prevent salt buildup and ensure even distribution through watering. Granular options can also work when applied as a top-dress with careful irrigation to avoid root burn.
What NPK ratio is ideal for crepe myrtles?
Crepe myrtles generally thrive with balanced or slightly bloom-focused formulas. Common ratios like 8-5-7 or 10-15-9 support flowering while maintaining healthy foliage. Avoid high-nitrogen formulas that promote excessive leafy growth at the expense of blooms.
How often should I fertilize crepe myrtles?
Most crepe myrtles benefit from annual feeding in early spring as new growth begins, with a follow-up light feeding if the tree shows signs of stress or poor bloom. Always follow product-specific instructions for frequency and dilution.
Are there cautions when fertilizing crepe myrtles?
Avoid over-fertilization, which can lead to leaf burn, excessive vegetative growth, or salt buildup in the soil. Water thoroughly after application when the product requires it, and refrain from applying during periods of drought or extreme heat unless the label advises otherwise.
What about soil and site considerations?
Crepe myrtles prefer well-drained soil and full sun. If your soil is heavy or clay-based, a soil amendment can improve drainage and root health. Fertilizer should complement, not replace, proper pruning, irrigation, and mulch practices.
How to choose by buyer type?
- First-time crepe myrtle owners: choose a complete liquid fertilizer with easy instructions (for predictable results).
- Busy homeowners: consider a granular option for long-lasting feeding with less frequent applications.
- Medium to large landscapes: a mix of granular and liquid presets can provide sustained bloom support across multiple trees.

FAQ
- What is the best NPK ratio for crepe myrtles?
Balanced or bloom-oriented ratios such as 8-55-7, 10-15-9, or similar blends support blooming while maintaining foliage health. Avoid very high nitrogen formulas that encourage leafy growth.
- Can I fertilize crepe myrtles during the growing season?
Yes, but follow the label’s timing. Spring feeding as new growth begins is common, with a light follow-up if needed. Avoid heavy applications during peak heat without guidance.
- Should I use liquid or granular fertilizer for containers?
Liquid fertilizers are usually easier for containers, ensuring even distribution with water. Granular options can work if paired with careful irrigation to prevent salt buildup.
- How often should crepe myrtles be fertilized?
Most trees benefit from annual feeding in early spring, with optional follow-up in mid-season if growth or blooms appear lacking. Adjust based on soil fertility tests and plant response.
- What signs indicate over-fertilization?
Yellowing or burned leaf tips, excessive leaf growth with few blooms, or soil salt crusting can signal over-fertilization. Dilute applications according to directions and water deeply after use.
- Are these products safe for other flowering trees?
Many of the listed products are designed for crepe myrtle and other flowering trees; always check the label for compatibility with your plant species before applying.
