COLD FRAMES AND PITS 



COLD FRAME.— This is the term used for the low glass structure in use for protecting such 

 plants as are not sufficiently hardy to withstand the winter in the Northern States. The boxes or frames 

 used are simply two boards running parallel with each other and nailed to posts to secure them in line, 

 the one at the back or north side being ten to twenty inches in height, and that for the front or south 

 side being eight to twelve inches, according to the height of the plants desired to be grown in them, 

 which gives pitch enough to carry off the rain and to catch the sun's rays. The width between these 

 boards should be enough to take the length of a six-foot sash, which is the most convenient size. Quite 

 a number of half-hardy, bulbous plants will be found to succeed well and give great satisfaction in 

 such an erection, more especially if an additional protection of mats or light wooden shutters, or both 

 is given in very severe weather. Cold frames are also useful for forwarding a few clumps of Lily of 

 the Valley, Crocuses, Erythroniums, Scillas, Chiondoxas. or other bulbs, which may be taken up from 

 the open ground, potted, placed in the frame and kept dark for a few days to draw the flower spikes 

 well up, and thus brought into flower a few weeks earlier than those out of doors. 



COLD PITS are identical with Cold Frames, except that an excavation of from two to four feet 

 is made below the general level of the ground so as to admit of larger plants being placed in them. The 

 sunken pit, however, is a better protection than the cold frame on the surface ; for when sunk to the 

 depth of two or three feet and covered with glass, it will resist a much heavier frost than the frames on 

 the surface. They are, therefore, to be preferred for protecting all half-hardy bulbs grown in pots, 

 which, when successfully wintered over, can be brought out and flowered in the house, or plunged or 

 planted out in the open border. They are also excellent, on account of their coolness, for retarding re- 

 serves of such bulbs as Hyacinths, Tulips, Narcissus, Freesias, etc., and such plants as Carnations, 

 Roses, Azaleas, Spirseas, Camellias, etc., which may be removed to the conservatory or Window- 

 garden at pleasure, and where on account of more heat and light they will soon be forced into flower, 

 thus keeping up a fresh supply of bloom throughout the the winter and spring months. Care must be 

 taken that both cold frames and cold pits are well drained, either from the nature of the soil or other- 

 wise, as water standing in them would be destructive to the plants, whether planted in the soil or 

 grown in pots.
