Shrubs next to houses
Howdy all
We have a very large old (20 years?) clematis right next to the corner of our house. It grows across the upper half of the house frontage. The trunk is now quite thick. Concerned about the overall size of the plant, during the winter I determined to take the whole lot down, and replace it. However I wimped out after I'd got halfway - couldn't bear the thought of doing away with it completely. If I keep cutting the upper half of the plant down annually, so that it doesn't grow overall in size, is it reasonable to think that the root system will also be kept in check? Cheers John |

Hi John,
My view; after 20 years, the root system on your Clematis is going to be as established as it ever will be. I really don't think it will increase much more in size than what it has already. I guess it is a 'montana' type? early flowering. If so, these are in prune group 1 for Clematis i.e. they flower on growth produced the previous season and following your strategy could mean much fewer flowers. For group one plants all that is required is a light trim immediately after flowering to keep the plant controlled. Martin Quote:

By "cutting it down annually" I meant "cutting it down in size", or "cutting it back" -- not actually cutting it *down*, if you see what I mean. John |

John You can John but if you want the flowers then do it each June after flowering, if you do it in winter it won't flower (I am assuming like Martin its a Montana type) -- Charlie, Gardening in Cornwall Holders of National Collections of Clematis viticella and Lapageria rosea cvs http://www.roselandhouse.co.uk |
