Backcountry Blend Bloom is a controlled release granular base nutrient. It can easily be applied to soil to provide your plants with the most ideal array of nutrients for the flowering stage. Backcountry Blend Bloom is part of the Backcountry Blend Outdoor Feed Program. Backcountry Blend Bloom contains a full spectrum of nitrogen (N), phosphorus (P), potassium (K), and calcium (Ca) that are measured specifically for the flowering stage. The Bloom formula includes higher levels of phosphorus (P) and potassium (K) that plants require during the flowering stage. Phosphorus plays a key role in essential functions of the plant such as photosynthesis, transfer of energy, and nutrient movement through the plant. Potassium aids in the conversion of phosphorus into energy your plants can use and strengthens cell walls to support larger yields. It can either be applied by top-dress application or be mixed throughout the soil. The low application rate makes feeding simple by only requiring application every 3-5 weeks so you can focus on tending to your plants to get the best results possible.
