40 CELERY. 



If I watered them to avoid the wilting, I 

 should produce a mildew, and the plants 

 would "damp off" at the root. Celery 

 needs but little water, and that in the 

 form of dew. Hot-beds should be wa- 

 tered at the upper part and not at the 

 lower, otherwise the whole crop is endan- 

 gered. It is easy to know from their 

 appearance whether the plants require 

 watering, for in such case their leaves are 

 of a deeper color, and smaller, than of 

 those which do not need it. My plan is 

 to water twice a week, and shade the 

 beds when the sky is clearest ; say from 

 10 A. M. to 4 P. M. 



Gardeners will have observed that in a 

 hot-bed, the plants growing in the shade 

 of a cross-bar of the sash are invariably 

 healthy. They are worth much more
