The best approach is to prune your peonies back after frost has blackened the tops. This is usually in early fall. Just cut the tops off and remove them from the garden. When the weather warms in the spring, your peony will sprout again. You can prune off any winter damage your jasmine suffered. If this involves cutting everything down to soil level, go ahead and do it now. Jasmine prefers warm temperatures and won't begin to grow until the weather suits them. Depending upon the type of jasmine you're growing, it may be too tender to survive the winter weather in your garden and you may have lost your plant over the winter months. Wait another 3-4 weeks - if you don't see any new growth, you'll have to replace your jasmine. Your Hydrangea can be cut down to about 12-18 inches above the soil level. Some develop flowers on new growth that is produced on old stems and others will develop flowers on the new growth of the season. Since we don't know which type you are growing, the safest way to prune is to leave some old growth on the plant. If you find your plant sprouting new stems at soil level and developing flowers on those new stems, it doesn't need the old growth to flower. If this is the case, next spring you can cut the entire hydrangea down to ground level before new growth begins. Enjoy your garden!
