E.B. Stone Ultra Bloom 4 LB
Is formulated without nitrogen to aid in the development of flower and fruit buds. Ultra Bloom also helps plants resist diseases and cold weather damage. Although it may be used on all plants throughout the year, it is especially recommended for Azaleas, Camellias and Rhododendron when flower buds begin to form in late summer, fall and winter. Ultra Bloom is blended with humic acid and beneficial soil microbes including mycorrhizae.
