What do I prune in fall & winter. Please be specific.
Linn County Oregon pruning
Thank you for your question. Before I can be specific in answering it, it would be helpful were you more specific about what type plants you are referencing. Trees and shrubs, ornamental grasses, bulbs, etc., etc. OSU has many publications about pruning, but there is no "one size fits all," and knowing the species would narrow the answer to relevant information. Thank you.
Perennials include clematis & climbing heritage roses
Thank you. When to prune clematis depends on what variety you have. Here is an article which is as specific as we can be with what we know: https://extension.oregonstate.edu/news/clematis-climb-special-place-garden “Heritage” and “climbing” roses each describe different characteristics, whose combinations have different pruning requirements: https://www.bookstore.ksre.ksu.edu/pubs/mf799.pdf If you have more information about your plants’ specific varieties, we can address them, rather than general practices.
