Spring in My Yard ! And My Knock out roses are in bloom – Easiest roses I have ever grown Lisa
Introduced in 2000, ‘Knockout‘ rose quickly became the best-selling landscape plant in the country. It had everything — showy, continuous blooms; compact growth habit; tough-as-nails constitution; and, best of all, no need to spray for black spot disease.
Some ”Knockout” roses feature blooms that are hot pink (almost red), while others are a true pink. The “Blushing Knockout” rose (Rosa x “Radyod”), which grows in USDA zones 5 through 9, features a teacup-shaped bloom that is bright pink set against dark green leaves.
Feeding. Knock Out roses are heavy feeders, just like other roses. Apply a balanced fertilizer at a rate of 2 to 3 pounds per 100 square feet between two feedings in early spring. Apply an additional 1 to 2 pounds of balanced fertilizer per 100 square feet once buds form and continue every four weeks until mid-August.
