I have two honeysuckles in my back garden. They have not been pruned in ages and flower poorly now. However, they offer a little privacy at the top of the fencing, from the adjacent garden, which is nice. I would like them to flower better. Do I cut them from the base (hoping they will grow back well) or just prune near the top and plant some dwarf buddleia or something under them? Do I need to cut at a certain section in the stem? Also, If I plant some spring bulbs, would I need to remove the layer of gravel scattered around the bordering in my garden?
