Unique blend comprised of time release fertilizer and 30% Biochar as a soil conditioner.

For best results, fertilize twice a year. Early spring to encourage new growth and then again during the middle of the growing season to replace any nutrients that are being depleted.

18-5-12 plus Biochar

Perfect for bamboo care, this time release fertilizer combined with 30% Biochar as a soil conditioner. After 20 years of trials, this is the best fertilizer we have found to allow for long term nutrient availability and prevention of excess runoff and leaching.

A recent study on our biochar by the University of Georgia demonstrated the biochar had a water holding capacity of up to 158.4% (meaning 1.584 kg-water held by 1.0 kg-dry biochar).

This well balanced time-release fertilizer is applicable for all soils. The time release assists in making nutrients available for bamboo on a timeline that corresponds to the bamboo's nutrient uptake capabilities. The balance of NPK specifically correlates to the needed levels for optimal bamboo growth while minimizing waste and leaching in soils.
