probio carbon – CalMag Bonsai

A new product developed in 2024 to help calcium deficiencies in trees. In general, the bioavailable Ca:Mg ratio should be 2:1. Sometimes in soft water areas calcium is not bioavailable at an effective level for alkali environment trees. Deficiency may then result in disease symptoms. To combat this, we have developed a calcium rich shell product coated with plant growth promoting bacteria. These bacteria act as a delivery vehicle to bio transform the calcium in the shell and deliver it in a form to where it's needed in the tree. Apply twice per season in soft water areas or when using rainwater, once per season in hard water areas is sufficient.
