Tree and Shrub Fertilizer:
Slow-release nitrogen fertilizers are best for woody plants, with one-third to one-half of the nitrogen in a water-insoluble, slowly available or slow-release form. Shrubs and trees absorb fertilizer during their active growth period: from spring, when growth begins, to late summer and early fall.
Prices:
