Ah! Well I do practice "territorial pruning"
I used to grow clematis, for example, over deciduous shrubs.....great for summer colour but they ruined the host shrubs. Never again.
I dont let associating plants touch my precious ...amd special....conifers. Taxus standishii, some dwarf cryptomerias, dwarf junipers, etc. they provide "perfect" unblemished shapes in the dormant seasons amd add lovely form and structure. No browning caused by unruly plants hosting upon them. Baggesons Gold, euonymous emerald n gold, santolinas.....both grey and the yellow forms......the coloured foliaged pittosporums, etc. etc will not be crawled over by nearby plants. Salix Hakuro Nishiki too will not be a host for any climber. I have persicara red dragon growing under it and it is "pruned" throughout summer tomaintain a purple under support/contrast to the cream/pink/pale green leaves. It looks good, natural and eye catching but I will not allow the salix to be grown over. I llike my areas of "cottage" planting but I have areas of heathers (which will not be grown over either), and areas of complementary and contrasting perennials that are not spoiled by intruding plants. I have evergreens trained ....e.g. Hollies are pruned to their natural shape (golden king, for example, is 10' high and 8' across. It is shaped naturally and looks good all year round. Never will I allow a climber over it)
When the summer colour has gone my "protected" evergreens and deciduous shrubs will make their show so, yes, "territorial pruning" for me for them
