Hi I'm Stan DeFreitas, Mr. Green Thumb. When you get into shrub roses, many of the shrub pavement type roses, in other words we have a rose that we are using as a filler area and many of our shrub roses will be growing along a walkway and you don't want someone getting snugged, you know grabbed out and reached by the rose so you are going to go back in and trim it from time to time and you are simply going to go back in and trim anything that is heading out. This has a nice big head on it but if this rose is going out into your walkway, you come back in and about a third of the way back you are going to trim off that flower head. Now most of your shrub roses don't have a big a flower as this. They are going to have much smaller flowers but you may have more of an abundance of flowers on them. Remember every time you trim back your shrub type rose you are going to get it to spread, you are going to get more potential flowers so trimming is a good thing on most of your shrub type roses, a) it keeps people from getting stuck as they walk by and b) it kind of keeps the plant more in bounds on the shape and the size and the form that you are looking for and that is important with most of our shrub type walkway roses, you want to keep everything within bounds.
