MASTERBLEND^® 10-30-20 is specifically designed for use as a blossom booster for Orchids, but it should not be limited to just one plant species,  It will work very well on all types of flowering material, especially when the grower requires improved bud set, bud count and better color and size of flowers. Use MASTERBLEND 10-30-20 throughout the flowering stage; switch back to the regular analysis when flowering is finished.  Fertilizer amounts need not be varied.
