Combining a balanced NPK ratio with a comprehensive chelated micronutrient package and a built-in soil penetrant, Magnum Rose Food delivers everything roses need to produce abundant, vibrant blooms and maintain robust structural health season after season. Available in a 3 lb format to suit home gardeners and larger growing operations alike.

Key Features & Benefits

• 8-10-8 NPK Ratio: Balanced formula with elevated phosphorus to support root development and blossom production alongside the nitrogen and potassium needed for strong stems, foliage, and disease resistance.
• Chelated Micronutrients: Fully chelated trace elements remain plant-available across a wide soil pH range, preventing the mid-season deficiency symptoms — yellowing, poor coloration, weak stems — that commonly affect roses grown in challenging soils.
• Built-in Soil Penetrant: An integrated wetting agent ensures nutrients reach the root zone efficiently, even in compacted or heavy clay soils where water and nutrient infiltration can be uneven.
• One-Step Simplicity: A complete fertilizer in a single product — no need to source and blend separate macro and micronutrient supplements for a comprehensive rose feeding program.
• Formulated for All Rose Types: Works equally well for hybrid teas, floribundas, climbers, miniatures, shrub roses, and heritage varieties in garden beds and containers.
• Water Soluble: Fully dissolves for use as a soil drench or diluted feed, delivering nutrients directly to the root zone for fast uptake and visible results.

Who Should Use This

Magnum Rose Food is ideal for home gardeners, landscape professionals, and greenhouse growers who want a single, reliable fertilizer that covers all of a rose’s nutritional requirements without the complexity of managing multiple separate products. It is particularly valuable for growers dealing with poor-quality soils, challenging pH conditions, or repeated micronutrient deficiency issues in their rose plantings.

Compatibility

Magnum Rose Food can be applied as a dissolved soil drench around the root zone or as a foliar feed when diluted appropriately. It is compatible with most other plant care inputs and can be integrated into existing rose maintenance programs. The built-in soil penetrant enhances delivery in dense soils. Available in 3 lb.

Frequently Asked Questions

How often should I fertilize roses with Magnum Rose Food?

For best results, apply Magnum Rose Food every 2–4 weeks during the active growing season, from early spring through late summer. Reduce or stop feeding in late fall to allow plants to harden off before dormancy.

Can I use Magnum Rose Food as a foliar spray?

Yes. When diluted to the recommended rate, Magnum Rose Food can be applied as a foliar spray for rapid nutrient delivery. Apply in the early morning or evening to minimize evaporation and avoid leaf scorch, and avoid spraying during bloom to protect flower quality.

Is Magnum Rose Food suitable for newly planted roses?

Newly planted roses should be allowed to establish for several weeks before receiving their first fertilizer application. Once roots are established and new growth is visible, Magnum Rose Food can be introduced at a reduced rate and gradually increased to full strength.

What are the signs of micronutrient deficiency in roses?

Common symptoms include interveinal chlorosis (yellowing between leaf veins while veins remain green), distorted or small new growth, poor bloom coloration, and weak stems. Magnum Rose Food’s chelated micronutrient package is specifically formulated to address and prevent these issues.

What size should I choose for my growing operation?

The 3 lb size is ideal for home gardeners with a small to medium rose collection who want to trial Magnum Rose Food or only need seasonal quantities. The 25 lb bag is the best choice for professional landscape use, large rose gardens, or growers who want the best value per application.
