What can you plant in your landscape that will bloom beautifully from spring
through fall? Hands down, the longest blooming period goes to the Knockout
Roses! Here in zone 7, they start blooming around early April and
continue on to late fall. This past fall, my double reds continued with
blooms until Thanksgiving which was many weeks beyond hard frosts and
remained in leaf through early December.

Plant these gorgeous specimens in well drained, fertile soil in full sun.

With little attention, they will put on a spectacular show for months on
end. The Knockout Roses are smaller shrub plants maturing around 4 feet tall
with about a 3 foot width. They are easily maintained as an even smaller
size with regular shearing.

Space the roses 3 to 4 feet apart for a dramatic hedge. To keep maintenanceto a minimum, prune them back anywhere from 6 to 12 inches above ground in late winter or early spring while dormant making certain to prune out any broken or damaged branches.

Mulch with organic matter such as aged compost or aged manure mix. Spread the mulch at least 3 inches deep around the plant leaving a welled area at the immediate base of the plant of around 3 to 4 inches wide so the mulch doesn’t touch the bark of the plant. Apply an organic fertilizer designed for roses as directed on the label.

As with other roses and plants with thorns, deer are not really drawn to the
Knockout Roses, so they do make dazzling color in areas where deer may be a
problem. The Knockout Rose Family has shown great resistance to the most
common problems of other roses such as black spot, mildew and rust.

With their extra long blooming period and practically no health problems, the Knockout Roses can be the best answer for many landscaping spaces.
