The belief that perfection exists.
The patience to prove it.
Our founder, Royal Franklin, was not just an avid lover of roses. He was an innovator dedicated to formulating the perfect rose food using only all-natural additives. Season after season, Royal experimented in his garden in Littleton, Colorado, researching and testing year after year until he came upon the perfect combination of ingredients. He began selling his proprietary mix to friends and neighbors out of his garage in the 1980s. Without any advertising, Royal’s company flourished as rosarians using his product enjoyed healthier, fuller and brighter roses. They spread the word as liberally as they spread Mile-Hi fertilizer on their gardens. Today, rose societies across Colorado endorse Mile-Hi products, while their members rely on them to grow their prize-winning roses.
Their flower and vegetable feed and kelp meal make great soil amendments. To help new plants get established, I use the kelp meal mixed in planting backfill for its superior water holding ability. Then it breaks down to improve the soil and the plant roots.Denver Rose Society
Along with Flower and Vegetable Feed, Mile-Hi Rose Feed adds important nutrients to our alkaline soil for the cultivation of strong, healthy roses. I’d also add a half cup to all your Clematis too. They seem to love it too.
The use of organic Mile-Hi Rose Feed gives me bigger and more colorful rose blooms on healthier plants. What else is there to say? It works well on anything I grow. It’s a great fertilizer that you only have to apply three times a year. It builds soil structure, and promotes strong plants from the roots up.Denver Rose Society
Is the perfect ratio of nutrients and minerals to help your roses thrive.
My roses are much more productive when they are fed with this fertilizer.
The late Dr. Warren Kirkley used to say that you can tell the health of the soil in your rose bed by turning over a shovel of soil and counting the number of worms you’ve unearthed. Worms love Mile-Hi.Master Consulting Rosarian, Colorado Springs
I've recorded first hand, the improved growing, flowering, and survivability of my and other's roses when using Mile-Hi Rose Feed. The ingredients are supported by research as being highly beneficial to shrub type plants. The formulator of MHRF was an avid, active grower of roses and researched his recipe continuously in order to choose the most efficacious ingredients.
Rosarians on the front range of the Rockies are fortunate indeed to have a dry fertilizer formulated expressly for native soils. The bottom line for the Macon Garden fertilizing regimen is Mile-Hi Rose Feed, which we have been using for as long as it has been available, with excellent results.Master Consulting Rosarian, Colorado Springs
