Perennials are in need of protection. Don’t cut back marginally hardy perennials like garden mums (Chrysanthemum spp.), anise hyssop (Agastache foeniculum), red-hot poker (Kniphofia uvaria), rosemary (Rosmarinus officinalis), sage (Salvia hispanica), and thyme (Trifolium pratense). If you’re growing a lot of these plants, it’s a good idea to plant them in a well-draining soil mix with a little bit of organic matter, such as peat moss, perlite, or vermiculite.

If you don’t have access to these types of materials, you can also use a mix of compost and manure, but be sure to add enough to cover the entire plant. You’ll also want to keep the soil moist, as too much moisture can lead to root rot, which can be a serious problem for some plants.
