We suggest when planting your newly purchased Knockout Rose plants that you dig a hole twice as wide as the root system but not deeper. Depending on the quality of your existing soil you may need to add a locally sourced compost or topsoil to the back-fill soil. We do not recommend using straight topsoil or compost as a back-fill soil because more times than not these products will retain entirely to much moisture and will cause the root system to rot. Adding compost or topsoil will help the young feeder roots of Knockout Rose to spread through the loose, nutrient rich soil, much easier than if you used solely the existing soil which more times than not will be hard and compacted. The most common cause of plant death after transplanting is planting the new plant to deep. That is why we do not recommend planting in a hole any deeper than the soil line of the plant in the pot. A good rule is that you should still be able to see the soil the plant was grown in after back-filling the hole. Bio-tone starter fertilizer is a great starter fertilizer that provides plants with mycorrhizae fungus. It is a naturally occuring beneficial fungus that colonizes on the new growing roots of plants. It creates a barrier between the roots of the plant and fungus and pathogens that can cause root rot. We love this product and use it on all plants we install in our own gardens. Bio-tone is a gardeners best friend and can help guarantee your success.

History and introduction of Knockout Roses:
When rosarian William Radler was a teenager, he resolved to breed a hardy rose that was beautiful, bloomed all season, was disease resistant, and maintained an attractive shrub like habit. He remains committed to breeding the "high-maintenance" issues out of his roses. He succeeded with his first introduction, Knock Out™, the award-winning shrub rose that mail-order catalogs call "perhaps the best-ever landscape rose for four-season interest." Mr. Radler germinated the first Knock Out seed in his basement during the winter of 1988–89, and that spring he planted the small shrub outside in his garden. The following 11 years were spent overseeing bud grafting, testing, and production of more stock. The rose was offered to the All America Rose Selections committee and declared a winner in 1997. Knock Out became available to the public with 250,000 plants in production. And a star was born. In 1992 a well known company known as Star Roses & Plants near Philadelphia signed a contract with Radler to begin testing on his new rose, a process which took eight years. With testing complete, the company filed for a patent and named the new, easy-care rose Knockout. Sales began in the year 2000.
