Knockout Roses

The very popular and easy to grow, disease-resistant Knockout Roses are probably the best way to start with rose gardening.

Planting a rose from the Knockout family does not mean to neglect everything we have learned about rose care.

A sunny site, well-drained with sandy-loamy soil is still the best way to start growing roses. Although Knockouts are considered to be low maintenance and disease-resistant roses, the plants are not maintenance-free and need food to bloom in the vigorous way they are expected. No food (fertilizer) means no or fewer flowers.

Anyway, the rose requires minimal care. You don’t have to spray or fuss over them to keep the flowers blooming all the time.

Plant the Knockout’s in mixed beds and borders, as a hedge, individually among shrubs or other plants. They will do well everywhere.

If you think the flowers need pruning, prune them in spring after the frost period, as I recommend in my Knock Out Rose Pruning-guide.

Varieties of Knockout Roses 

Each of the Knockouts have their unique look, and choosing them will add significant results to your garden.

I will list some of the most popular varieties starting with the classic red Knock Out Rose Bush.
