50 ALPINE OR ROCK PLANTS. 



SUMMER TEEATMENT. 



ABOUT the beginning of May, or sooner, if all danger 

 from frost is considered over, the collection of Alpines 

 may be entirely removed to their Summer quarters, 

 as already described (see Plate, Fig. 5). It is pre- 

 sumed this space has received a general dressing with 

 the hoe and rake, besides a fresh layer of riddled 

 coal ashes. Afterwards, they must be kept clear of 

 weeds, and the vermin destroyed, by scattering some 

 hot lime over the ashes, which forms an effectual 

 remedy. For the same purpose, Mr. M'Intosh re- 

 commends watering with lime water. When the 

 weather becomes hot, the plants must be supplied 

 abundantly with water every night, commencing 

 about six o'clock, or sooner, if the sun's influence is 

 removed; watering them completely over head, beds 

 and all, which assists in keeping the soil moist in 

 the pots, and the ground cool all around them, a 

 condition essentially requisite at this period. 



In the morning, should it have the appearance of 

 being very hot, they can be gone over in the same 

 way. But I have found once a day sufficient, when 

 in a suitable place, and watered effectually.
