PREMIUM CRAFTED EST. 1983 NELSON PLANT FOOD NutriStar 10-15-9 Flowering Tree Fertilizer 2 lb — Slow-Release Bloom Booster

NutriStar 10-15-9 is a slow-release, low-salt granular fertilizer formulated to boost bloom count and flower size on crape myrtle and other flowering trees.

Designed by Nelson Plant Food, this professional-grade 2 lb. blend supplies balanced macronutrients plus essential micronutrients in staggered-release forms to feed flowering trees steadily over weeks. Ideal for both container and in-ground plants, the formula supports regrowth after pruning and helps flowering species produce more abundant, larger blooms without sudden nutrient spikes. Use in spring and follow with periodic maintenance applications to keep trees flowering through the season.

How should I apply NutriStar 10-15-9 to my crape myrtle?

Apply the full recommended rate once early in spring when new growth begins, then follow with maintenance doses every 60 days at about half the initial rate. Spread evenly around the root zone, avoiding direct contact with the trunk or foliage, and lightly water in to activate the granules.

• Initial application: full label rate at start of active growth.
• Maintenance: half-rate every 60 days while blooming.
• Application zone: drip line to root flare for best uptake.
• Watering: light irrigation after spreading to begin nutrient release.

What benefits will I see after using this fertilizer?

This mix supplies nitrogen, phosphorus, and potassium in complementary release rates so plants receive both an immediate boost and ongoing nutrition. Elevated phosphorus encourages bloom production, while included micronutrients (iron, manganese, zinc, copper) support color intensity and overall plant vigor.

• Greater number and size of flowers due to higher available phosphorus.
• Improved regrowth and recovery after pruning from balanced nitrogen sources.
• Stronger color and bloom quality from added trace elements.
• Gradual feeding minimizes fertilizer burn risk with low-salt formulation.

Which trees and growing situations are a match for this formula?

NutriStar 10-15-9 is tailored for a wide range of flowering trees that benefit from bloom-focused nutrition. It works well in garden beds, landscapes, and patio containers where flowering trees need steady, reliable feeding.

• Recommended for crape myrtle, desert willow, mimosa, orchid tree, vitex, and viburnum.
• Also suitable for flowering pear, crab apple, Mexican plum, Texas mountain laurel.
• Use for both new plantings and established specimens in ground or containers.
• Apply at planting or top-dress established root zones for seasonal blooms.

Is this safe for container-grown flowering trees and patios?

Yes—formulated with multiple nitrogen sources and low overall salt, it feeds steadily without causing abrupt root stress in containers when used as directed. Adjust rates for pot size and ensure adequate drainage to avoid salt build-up over successive applications.

• Use reduced rates for small pots to prevent nutrient overload.
• Top-dress or mix into potting medium at planting for best results.
• Feed up to four months of benefit per application, following label timing.
• Rinse or repot occasionally for long-term container health.
