Designed for Maximum Flower Production
During the flowering stage, plants require increased phosphorus to support energy transfer, root activity, bud development, and flower formation. The 10-30-20 nutrient ratio delivers targeted nutrition precisely when plants need it most.

- Increased flower count
- Larger blossoms

While phosphorus drives flower development, healthy plants require much more than a single nutrient. Jack's Professional 10-30-20 includes a complete spectrum of fully chelated micronutrients that remain readily available for plant uptake.
These essential trace elements help support:
- Chlorophyll production
- Nutrient absorption
- Healthy foliage development

The result is a fertilizer that supports both beautiful blooms and overall plant vitality.
