20-5-30

High Potash Formula

20-5-30 High Potash Formula is specifically designed for greenhouse growing media which have built up appreciable amounts of available Phosphorus. It can be used effectively on crops such as Carnations, Mums, Snapdragons, Roses, etc., as well on most other crops which indicate a need for high Potash and low Phosphorous. Over 40% of the Nitrogen is in the preferred Nitrate form, the formula is practically non-acidifying, and it is excess salt free. It is best however, to soil test if the grower wishes to use the 20-5-30 on a continued basis.
