About this product
Autumn Universal Complex is a granular NPK fertilizer formulated for pre-winter feeding of garden crops, fruit trees, ornamental shrubs, bulbous plants and lawns. Its 5-14-21 grade delivers a small dose of nitrogen for late-season vegetation alongside elevated phosphorus and potassium that support wood lignification, root development and successful overwintering. Added sulfur and silicon reinforce winter hardiness and moisture regulation. Granules are worked into the soil before frost across all soil types.
