Roses are heavy feeders that need a constant supply of nutrients to maintain growth and blossom production. Burpee Natural & Organic Rose + Bloom Granular Plant Food is formulated to supply that. A flush of nutrients occurs immediately and slow-release nutrients continue to feed your plants for up to 3 months; beneficial microbes are included to help keep soil and plants healthy. It’s ideal for container plants, established beds, and individual bushes and other flowers. OMRI labeled for organic use.
