| I have one of those small spireas, can't remember the exact name but it has lime yellow foliage and bright hot pink flowers. I really love the shrubs, but in my tiny yard they have finally after three years just gotten way to big and show no signs of slowing down. I need to get them under control. I've been pruning them, which has been fine, but I also need to control their footprint underground. Can they be "divided" or somehow freshened by cutting up their root stocks? If they were perrenials what I'd do is dig them up and root prune them, but these are shrubs so I don't know what to do. But they are strangling the area of the garden where they grow, and I can't afford this in my tiny yard space. I have thought about yanking one of them and replacingwith cinquefoil, but I like the repetition. |

| 'Limemound' most likely. Can they be "divided" or somehow freshened by cutting up their root stocks? No. Plants have an ultimate size. You can try and prune to keep them to fit your wishes and not theirs, but it is a lot of work. Dan |

| How are you pruning them? My understanding is that they can be cut to stubs in early spring. |

| They can be cut back very hard. If it's a Japanese spirea, and since you're in PA, you may be interested in knowing that Spirea Japonica is on PA's invasive plant list. |
