Full Description

Easy to Care for Sunny Knock Out Rose Shrubs

The Sunny Knockout Rose is the only fragrant member in The Knock Out® Family. It has a slightly more compact and upright habit than The Knock Out® Rose with bright yellow flowers that fade quickly to a pastel cream color. The yellow color stays more intense during cooler times of the year. The dark, semi-glossy foliage contrasts nicely with the bright blooms.


Planting Information

We suggest when planting your newly purchased Sunny 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 Sunny 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. Watering Sunny Knockout Rose: After back filling and lightly compacting the 50/50 mix of existing soil and compost give the Sunny Knockout Rose a good deep watering. This is not to be rushed. Most of the water you put on the plant at first will run away from the plant until the soil is soaked. A general rule of thumb is to count to 5 for every one gallon of pot size. For example a one gallon pot would be watered until you count to 5 a three gallon pot would be 15 and so on. Check the plant daily for the first week or so and then every other day there after. Water using the counting method for the first few weeks. You’ll want to water the bushes regularly after planting until they’ve been well established. We like to tell folks that when watering Roses its best not to water the foliage of the plant. Water at the base of the plant near the soil line only. Although Knockout roses are generally resistant to Black spot there are other foliage diseases that can effect roses in general that are favored by wet foliage conditions. Gator bag Jr. can be used to help aid in this process and also provide plants with a good soaking due to the slow release of the water into the root-zone of the plant. Soaker Hoses can also be used to water when planting a long hedge.
