Pruning or cutting back 'strawberries n cream'
I have three 'Straweberries n cream' orn. grass bushes in my yard. They are growing fast, which is nice. But they are becoming wide and "fat". They are becoming a little overpowering to the rest of the garden.
When and how should I cut these back? This is my first yard and I'm afraid I'll kill em or mess them up if I do it wrong. Any help/advice is appreciated. Thanks!
