8. Take Care of Those Tender Species Long Before Frost Hits
If you have tender species like begonias and dahlias, be sure to take them out of the ground before the first threat of frost. Cut back the stems and then gently lift them out, clean them of soil and then store them in trays of sand or dry compost, leaving just the top of the crown visible. Keep the trays in a cool place that isn’t subject to frost until they can be replanted when the warmer months arrive. If you live in a very mild area where there is no concern of freezing, you may be able to protect them without taking them out of the ground by covering the crowns with a thick blanket of mulch.
