A variety of shrub rose is called rosario rugosa.The roses produce a single flush of flowers, ranging in color from white to deep pink.This rose variety is easy to maintain and thrives with only lightPruning each season.If the plant becomes overgrown, heavier renovationPruning is not necessary.
Step 1: Know when to cut back.
After the plant enters its dormant season, mostPruning should be done.This can happen between late autumn and early spring.After the danger of frost has passed, the best time to peck is in the early spring.Pruning makes plants vulnerable to cold winter frosts.If you live in a warm climate, you don't need to wait until spring as long as you wait in the dormant season.During the active growing season, deadheading is the onlyPruning you should worry about.Theheading should be done on an "as needed" basis during the summer.
Step 2: Determine if or not to deadhead the blooms.
It's not necessary to deadhead faded blooms before they drop for rosa rugosa shrubs.The rose hips are a part of the shrub's aesthetic appeal, and deadheading them would remove them.You can brush away the spent petals with your hands or leave the hips intact.If you still want to do it, deadheading prevents the bloom from going to seed and reduces the risk of disease.You can cut the stem at a 45 degree angle if you decide to deadhead.Continue throughout the flowering season, but stop sometime during the beginning of autumn, around October 1 or so.The shrub will be prepared for winter if the practice is stopped.
Step 3: Unhealthy stems should be removed.
Dead stems, dying stems and diseased stems are healthy stems.Each dormant season should see the removal of weak, thin stems.Cut stems at a 45 degree angle with a sharp cutting tool.You can determine if a cane has died by looking at it.Dark brown or black dying canes are usually shriveled.Any stem that is smaller than a pencil is a weak stem.At the ground level, dead canes should be removed.The crossing of dead wood and live wood should be crossed by the partially dead Stems.The live wood should be protected from harm with a small amount of dead wood.If you can't tell where the dead wood ends and the live wood starts, you should gradually cut it back until the center of the trimmed stem is white.
Step 4: Prune problematic stems.
Problematic stems refer to branches that grow at abnormal angles.Problems can be caused by wood that crosses other branches or rubs against other parts of the shrub.Light and air can't flow in between the canes, and as a result, these sections of wood are more likely to become damaged.To cut crossing or rubbing stems, go to a point below the problem area.If the stems grow back in the same problem the next year, cut them down to ground level to prevent the problem from recurring the year after that.
Step 5: As needed, thin out healthy stems.
Light penetration and air circulation should be promoted by the center of the shrub.Even if the wood in the center of the plant is healthy, you may need to trim it away if your rosa rugosa plant has grown too much.Shrub roses like rosa rugosa will flower on both new and older wood, so most of the old wood should be allowed to develop and maintain itself naturally when possible.Some of the healthy growth in the center may need to be trimmed if the plant interior becomes too crowded.Look for wood that did not bloom in the previous season.At a 45 degree angle, cut away two or three of these branches.
Step 6: Understand why renovation pruning is done.
If the roses start to look messy or overgrown, you will need to use renovationPruning to clean the plant up.It's important to note that renovationPruning can cause a slight loss of flower production the following year, but it is still beneficial to your plant overall.Rose shrubs are overextending themselves and their resources.It may take a few years for the stress to show, but once it does, your plant will be much weaker and have a hard time surviving.The first two or three seasons should be avoided.Doing so will allow the plant to establish itself more securely.Wait every other year to do an update on the plant once it establishes itself.If new growth is not vigorous enough or if the plant is weak, you may need to skip every other year.
Step 7: Wait until the season is over.
You should wait until the plant enters its dormant stage before you cut it down.If you wait until the last frost passes in early spring, you should be able to get rid of the shrub at any time.
Step 8: Don't remove suckers.
The main stem of the plant is referred to as a sucker.At the ground level, cut these suckers off.Aside from looking messy, the main problem with suckers is that they tend to grow too well and deprive your main rosa rugosa shrub of the nutrition it needs.Your main shrub will eventually die because of this.If you want to be more thorough, you can dig down to the root of the sucker and cut it off at its point of origin.
Step 9: One-third of the stems should be trimmed.
Cut down between 25% and 30% of the oldest stems on the plant.The stems should be trimmed to the ground."Ground level" refers to the height between the ground and 1.5 inches (4 cm) above it.Each cut should be made with sharp shears at a 45 degree angle.You should try to cut the plant down to a bud.The shrub should still be able to produce a new bud below the cut if you can't find a low bud.If your plant is weak, you may want to trim the branches to their new growth instead of cutting them all the way down to the ground.
