Snow is also fairly common, causing breakage on brittle limbs and trunks.
Since the month offers far too little time, start with the essential tasks that will help protect the garden during winter. Check the pots for hitchhiking insects before moving them inside. Shower the plants well from a hose to remove dust from the leaves before moving. During winter, reduce water and fertilizer while houseplants are relatively dormant. Many growers suggest removing leaves on hybrid teas and other smaller roses by mid-November to force the plants into dormancy.
