338 GREENHOUSE MANAGEMENT. 



end of two years a crop may be taken. In the fall, put 

 tip the frame and fill it with horse manure, banking np 

 against the outside of the frame with the same material. 

 Cover with sash and shutters to keep out the frost. 

 Early in March, remove the manure over the plants, wet 

 down the beds thoroughly, and handle the same as any 

 odd frame. 



WINTER RHUBARB. 



With but few changes, the directions given for the 

 forcing of asparagus will apply to rhubarb. The drills 

 should be somewhat further apart, and a pound of seed 

 will be sufficient for 300 feet of drill. In setting the 

 plants in the field, they will need at least three and one- 

 half by two feet, while in the greenhouse they should 

 have a space of from fifteen to eighteen inches square, 

 and if the roots are very strong twenty-four by eighteen 

 will be none too much. Nothing will be gained by set- 

 ting the plants before Jan. 1, or until they have had a 

 period of rest. After the stalks are half grown, liquid 

 manure can be applied to advantage once or twice a 

 week. If the soil is properly drained, the plants can use 

 large quantities, but it should not be used too copiously 

 unless the chill has been taken off from the water, other- 

 wise the growth might be checked. The Linnaeus is an 

 excellent forcing sort, but as with all other large varie- 

 ties, the crop will need to be harvested when about half 

 grown, if the plants are placed as thickly as recom- 

 mended above. The crown of the plant is quite tender 

 and care must be taken, when gathering the stalks, not 

 to break it off. 



For spring use, rhubarb may be grown in cold 

 frames, the same as asparagus, except that the plants 

 should be two or three feet apart each way. 



THE FORCING OF CAULIFLOWERS. 



While cauliflower is, to a considerable extent, forced 

 in hotbeds for spring use, it has also come into popular
