Planting Tips

One of the most important things you need to know if you want to grow Knockout Roses is that your rose bush needs a minimum of 6 to 8 hours of sunshine every day. That means choosing the right location is going to be crucial! Look for a sunny spot in the garden.

Once you have chosen the right location for your new rose bush, it is time to dig your hole! The hole needs to be a little larger than the container your roses are currently growing in. When the hole is ready, remove the bush from its container and gently loosen the roots at the bottom with your hands. Now you can plant it in the hole you have prepared, ensuring the plant base is level with the soil.

PRO TIP! Make sure you work the soil in the bottom of the hole to be loose and well aerated.

Watering Tips

After planting, you will want to water your rose thoroughly around the base of the plant and allow the water to soak in. This should be repeated as often as necessary over the first few weeks until it is fully established. Be sure to check on the plant regularly to make sure it has enough water. If you need advice about how much water your roses need, the staff at Northshore Nursery garden center in Knoxville, TN, will be happy to offer advice.

Fertilizing Tips

One of the great things about Knock Out Roses is that they will thrive even without using fertilizer. However, if you want to give them that little extra boost, you must wait until they have completed a full bloom cycle before using fertilizer. Stop by our garden center in Knoxville, TN and pick up fertilizer formulated especially for use with roses.

PRO TIP! The soil should be moist before fertilizing your roses, or you could risk burning the roots.

Pruning Tips

To maintain a steady size for your rose bushes, you will want to cut them back once a year to a height of around 12 inches. This should be done in Winter or Early Spring, whenever new shoots start to appear growing from the canes.

Winter Care Tips

Knock Out Roses are tough cookies, and they will survive through most conditions in the Knoxville area. However, if there happens to be a particularly harsh winter adding around 3 inches of mulch around the base of the plant will help insulate it against the cold. You may also want to wrap it in burlap to protect against winter winds.

Hopefully, these tips will help you to grow Knock Out Roses to be proud of. If you need help choosing the best variety to suit your garden, or if you need further growing advice, the team at our garden center in Knoxville will be happy to help.
