NutriStar 10-15-9 Granular Fertilizer for Crape Myrtle & Flowering Trees | Nelson Plant Food

NutriStar 10-15-9 is a low-salt, slow-release granular fertilizer crafted for Crape Myrtles and all flowering trees. It blends multiple nutrient sources to provide a steady supply of nourishment over time, helping plants access essential minerals as they grow and bloom. The formula is designed to feed soil biology and roots, supporting healthy development from early spring through the growing season.

Why this formula fits flowering trees

This blend is purpose-built for flowering trees, including Crape Myrtle, Desert Willow, Mimosa, Orchid Tree, and more. It combines balanced nutrition with targeted micronutrients to support vibrant growth and abundant blossoms without overwhelming the root system. The low-salt profile is gentle on soils and containers, making it suitable for a range of garden setups.

• Balanced ingredients may encourage regrowth after pruning and maintain steady growth between seasons.
• Micronutrients help support bright, appealing bloom color and overall plant health.
• Higher phosphorus content is associated with more bloom production in flowering trees.
• Elemental sulfur can help adjust soil acidity where needed, aiding nutrient availability.

What’s inside and how it helps

The formula includes a diverse mix: ureaform, monoammonium phosphate, potassium nitrate, potassium sulfate–magnesium, triple super phosphate, sulfur, magnesium oxide, and an array of trace minerals (ferrous, manganese, zinc, copper) to support flowering vigor. Five nitrogen sources with different release characteristics work together to feed trees over time.

• Multiple nitrogen sources provide a balanced, extended feeding pattern.
• Phosphates and potassium support strong blooms and steady growth.
• Trace minerals reinforce bloom color and plant health throughout the season.
• Formulation is suitable for in-ground beds and container plantings alike.

How to use for best results

Apply NutriStar for Crape Myrtles early in the spring at the full rate. For ongoing feeding, apply every 60 days at half the rate. This product is intended for both garden beds and patio containers, adapting to different growing setups.

• Container or bed application: spread evenly at the recommended rate and water well.
• Seasonal schedule: begin in early spring and continue feeding through the growing months.
