AN EXPLANATION OF TERMS 



fluous side shoots that form freely on fruit trees (especially 

 those trained against walls) during the summer. 



Brisk Heat. One can scarcely imagine heat being 

 brisk, a term that seems to associate itself with move- 

 ment. However, a " brisk heat " has its significance for 

 the trained gardener. I can scarcely translate it into a 

 fixed temperature, but I should put it somewhere about 

 65 Fahr. 



Callus. Two or three weeks after a cutting is placed 

 in suitable soil and temperature, a ring of tissue forms 

 at its base, and is called a " callus." From this roots 

 subsequently issue. 



Close Early. " Early closing," from the gardener's 

 point of view, alas ! does not mean shortened working 

 hours. It merely expresses in somewhat obscure English 

 the work of closing the greenhouse ventilators in good 

 time so that the temperature may rise without the aid 

 of artificial heat. By " closing early " the grower 

 " harbours sunheat." 



Crown. The dormant root of Lily of the Valley is 

 called a " crown." As each " crown" is small, the roots 

 are commonly sold in bundles of so many " crowns." 



Damp Down. When told to " damp down " the glass- 

 house, one is expected to syringe the walls and floor and 

 paths to create a " growing " (i.e. a warm, moist) atmo- 

 sphere. 



Damping Off. Little seedling plants, if crowded, are 

 apt to be attacked, at the base of the stem, by a fungus.
