Comparing Rose Fertilizers: Once-a-Season vs. Regular Feeding for Large Collections

My Schedule (350+ Roses)

Synthetic granular: Twice/year (early spring, mid-summer) — e.g., every 6 weeks.
Organic (fall): Mills Magic, alfalfa meal, composted manure — builds soil fertility.
Liquid boost: Miracle-Gro sporadically for bloom quality/quantity.

If it saves time, try it! But supplement with organics for long-term soil health and a liquid feed for peak bloom. No single product does it all.
