Planting instructions

It’s possible for the pink double knockout rose to survive in partial shade. However, in full sunlight, this plant exhibits better flowering, stronger disease resistance, and more vigorous growth. The soil for this plant should have good drainage, be slightly acidic, and have moderate moisture. Start the planting process for your pink double knockout rose tree by digging a hole that is as deep as the root ball and about twice as wide. Alternatively, the small stature of this plant allows it to grow well in containers.

Watering and nutrients

During the first growing season after planting, water your pink double knockout rose deeply about once or twice per week. When this plant is established, you should water it based on soil moisture. When the first few inches of soil have become dry, supply your pink double knockout rose with deep watering. Fertilize this plant a few times per year during the spring and early summer. When fertilizing, it’s ideal to use a phosphorus-rich mix, but a general-purpose fertilizer will work as well.

Pollination

The pink double knockout rose tree is a hybrid plant that does not produce high volumes of pollen or nectar. Instead, these plants serve a strictly ornamental role in the garden rather than providing a food source for humans and pollinator species. As such, you should not worry about pollination with this plant. Also, the lack of nectar and pollen ensures that very few bees and other insects will visit your pink double knockout rose, which is an immense benefit for those who want their garden to be as bug-free as possible.

Pruning

Pruning for a pink double knockout rose should occur during the later winter or early spring as the new growth is just beginning to emerge. Often, gardeners choose to cut back their pink double knockout roses significantly to control growth, at times removing a foot or more of growth. Additionally, the pink double knockout rose comes with the convenience of being self-cleaning, meaning that it drops its spent flowers on its own so that you don’t need to perform any deadheading.

Pests, diseases, and animals

However, the pink double knockout rose tree offers the perfect solution. For a rose, ithas incredible disease and pest resistance.

Achieving maximum results

One of the most advantageous aspects of growing the pink double knockout rose tree is that it can survive, and look beautiful, even in the absence of fertilization.
