Heirloom Boost & Bloom: For Season Two And Beyond
Heirloom Boost & Bloom is our house blend of granular fertilizer that we use on our roses here at the nursery. Give your roses the boost of nutrients they need to flower productively and continue to establish strong roots and new growth.
Only to be used on mature plants (season two and beyond), this granular fertilizer is too hard for young, first year plants to process and may burn the roots. This product is also not advised for roses in containers.
Use as a top dressing in the early spring, as plants are coming out of dormancy. We then recommend applying a ½ cup per plant every four weeks during the growing season.
