WINTER PROTECTION 



aa. Tender and ha If -hard y -plants. 

 Those marked with a star (*) are 

 tender and should not be exposed to 

 frost. They should also be kept in 

 the driest part of the pit. 



1. Alstrcemeria, canna, dahlia, 

 gladiolus, Milla biflora, montbre- 

 tia, oxalis for summer bedding, 

 tuberose, tigridia, Zephyr ant hes 

 AtamascOy Z. Candida. Keep the 

 above in dry house-cellars, where 

 no frost penetrates, temperature 

 35-40° F. Dahlias and cannas can 

 be covered with dry sand if prone 

 to wilt. Tigridias should be hung 

 up in bags to avoid mice. 



2. Agave, aloe, Lippia 

 citriodora, Datura 

 suaveolens, some of the 

 hardier cacti, e.g., Cereus 

 grandiflorus and Opuntia 

 Ficus -Indica, Cordyfine 

 indivisa, fuchsia, Yucca 

 gloriosa and probably 

 other genera and species 

 of succulent plants. Keep 

 at temperature 35-40° F. in 

 a very dry house -cellar, 

 with as much light as pos- 

 sible; too much moisture 

 is destructive.

No. 1.— One of the simplest and least 

 expensive forms of cold pit for small and 

 medium-sized plants. 



—A well-ventilated eold pit, roomier than the preced 

 ing one and not much more expensive. 



No. 3.— A shelved cold pit for wintering young stock grown 

 in flats, seedlings, rooted cuttings and grafts. 



No. 4. — A small plant cellar for wintering large plant 

 It is also excellent for storing vegetables and fruits, 

 combines perfert ventilation with extremely good protec 

 tiou against frost.

The above plants are commonly 

 handled in pits for various rea- 

 sons. In eastern Massachusetts, 

 with the possible exception of 

 those marked thus (*), they will 

 bear a few degrees of frost, if not 

 too long continued, without harm. 

 The average temperature 

 of the pit should be just 

 above freezing, say 35° F. 

 The value of these plants 

 depends upon not only 

 carrying them through the 

 winter in good condition, 

 but also in giving them a 

 good start in the spring. 

 For this purpose a cool 

 greenhouse must be pro- 

 vided; a cold grapery or 

 a house constructed from 

 the sashes used on the pits 

 is equally good, in which 

 the plants can be properly 

 grown until it is warm 

 enough to put them out-of- 

 doors. 



4. Anemone Japonica 

 and A. coronaria, Bel lis 

 perennis,Dianthus Caryo- 

 vhyllus (clove pinks and 

 European carnations from 

 seeds), Galax aphylla, 

 myosotis sorts, primula in 

 variety, including auric- 

 ula, Persian ranunculus, 

 Viola odor at a (tender 

 sorts), pansies, wall-flow- 

 ers, lettuce, cabbage, cauli- 

 flower and parsley. These 

 plants are advantageously 

 wintered in coldframes, 

 which should vary in 

 depth with the size of the 

 plant; sometimes the 

 plants are grown and flow- 

 ered in the frame, at 

 others they are bedded 

 out when the season per- 

 mits. 



5. Arisa?ma, arum, calo- 

 chortus(different species), 

 freesia in variety, iris 

 ( tender species), ixia, 

 sparaxis. The above plants 

 can be potted, November 

 to December, and carried 

 in a pit until wanted in 



il^O;--, the greenhouse.

 CULTURE IN. Fig. 2743. 

 The surface of Wisconsin 

 mostly varies between 

 gently rolling plains and 

 hills of moderate height. 

 Small lakes are numerous, 

 particularly in the north. 

 The soil presents all va- 

 riations, and with the ex- 

 ception of some rather" 

 large sandy and marshy 

 tracts, is mostly very fer-
