Fall Treatment of Plants with Reference to Frost 



Vegetables. — Perennials, such as Asparagus, Horse Radish, 

 Jerusalem Artichoke and Strawberries are entirely hardy. It is, 

 however, well to mulch them after the ground freezes, partly to prevent 

 alternate thawing and freezing, which tend to heave them out of the 

 ground, and partly to add plant food to be dug in in the Spring. 



Annuals may be put into four groups with relation to their 

 abihty to withstand frost, as follows: 



1. Entirely hardy. Those marked a may be sown or planted in 

 late Fall for early Spring use. The rest may be left in the garden to 

 be harvested as needed. For convenience it is well to mulch the root 

 crops to make digging easier: Broccoli, Brussels Sprouts, Corn Salad 

 (a), Kale, Leek, Parsnips, Salsify, Witloof Chicory (a), Spinach (may 

 be handled both ways). 



2. Hardy. These will stand a light freeze but should be harvested 

 before the ground freezes sohd. In the case of frosted Lettuce, thaw 

 out slowly in ice water and use at once. Carrots, Lettuce, Onions, 

 Peas, Rutabagas. 



3. Fairly hardy. These will stand a light frost and do their best 

 in cool weather: Beets, Cabbage, Cardoon, Cauliflower, Celery, Celery 

 Cabbage (Pe-tsai), Kohl-Rabi, Potatoes, Radishes, Swiss Chard. 



4. Practically all other vegetables need warm weather in which 

 to make good growth, and protection from even the lightest frost. 



Flowers. Perennials are, of course, hardy as to root, even 

 though their tops may be killed down. The following, however, 

 continue to bloom well after the first frost: Chrysanthemum, Gail- 

 lardia grandiflora, Antirrhinum majus. Coreopsis lanceolata, Lathyrus 

 latifoHus. 



Annual sorts growing from bulbs that are hardy and that therefore 

 can be planted in the Fall for Spring blooming, include: Lihes, Crown 

 Imperial, Hyacinth, Lily of the Valley, Narcissus, Scilla, Tulips. 



Narcissus for best results should be dug after flowering and allowed 

 to ripen before being replanted in the Fall. 



Plants with tender bulbs which should be dug after frost has 

 killed or blackened the tops but before the ground freezes, include the 

 following: Begonia (Tuberous), Caladium, Cafla, Dahlia, Gladiolus, 

 Tritoma, Tuberose. 



Of non-bulbous annuals which are not expected to last more 

 than one season, there are some that continue to bloom even after a 

 mild frost. Among these are Aster, Cosmos, Sweet Alyssum, Clarkia, 

 Marigold, Pansy, Ten-Weeks Stock, etc.
