All of our KnockOut Roses are grown in our Jumbo 1 Qt containers. They are big enough so they will bloom for you the first year in your garden. They are well-branched with buds and about 12-15 " tall when we ship them. You'll like the fact we keep them pruned & compact so they arrive to you in excellent condition.
Roses prefer a soil that is well drained and a soil ph from 6.5 -6.8. When planting in groupings, it is best to space the roses to allow sufficient air circulation. When you are ready to plant, make sure the container soil is sufficiently moist. Space Roses 3' apart. Dig a hole about 1 foot deep and 1 foot wide. Amend with organic material such as peat moss. Remove plant from the container and position the rose on soil pyramid so the bud union (swelling at the stem base) is just above the ground level. In climates where the winter temperature falls below 0 degrees F., it is best to position the rose 1-2 inches lower. Work soil around the root until the hole is three quarters full. Fill the hole with water and allow it to soak in, then refill again with water. After the water drains check to see if the bud union remains at the proper level. Fill the remainder of the hole with soil.
How To Grow
Roses prefer about 6 hours of sun per day. Roses will perform well if provided about 1 inch of water a week. Adding mulch helps retain moisture and suppress weeds. Apply about 2-3 inches of mulch but don't mulch heavily around the base of the plant.
Although this step may seem daunting to some, pruning help the plants in a number of ways including: removing dead wood, encourage blooms and new growth, provides shape to the plants and help improve air circulation around the plant.
Tools you will want to have at hand include a pruner and/or lopper as well as some thick, long gloves.
Take a look at the plant and begin at the base. Begin by removing any dead or dying wood. Then step back and taking another look to determine what you need to do to shape the plant. Shaping helps in creating air circulation in the center of the plant. Cut at a 45 degree angle and slightly above any buds.
Pruning time for Knockout RosesTM is in the spring. They bloom their best on new season's growth. Do not prune the first year, except to remove long canes or dead wood. Beginning the second year, Prune your roses by 1/3 to 1/2 in early spring and remove dead wood. Leave abut 4-5 healthy appearing canes that are evenly spaced. It is ok if the remaining shrub is only 12-18" above the ground.
We are a big believer in Osmocote as a slow-release fertilizer at time of planting! You can buy Osmocote at any good garden center or Walmart. We recommend using 2 tablespoons of this in the bottom of each plant's hole when planting. This is a slow-release fertilizer that releases small amounts with every watering. You only need to apply the Osmocote once per year.
