GREEN-HOUSE WATERING. 263 



APRIL. 



REGARDING the shifting or repotting of plants, the direc- 

 tions given last month may be followed. If the plants that 

 require it are not shifted, get them done as soon as possible. 

 Those that were repotted last month will have taken fresh 

 root in the new soil, and the advantage will soon be per- 

 ceptible. In order to strengthen the plants, and keep them 

 from becoming drawn and spindly, admit large portions of 

 air every mild day. Indeed, there will be very few days 

 in this month that a little air may not be given, always 

 observing to divide the quantity regularly over the house, 

 in cool nights closing in time. About the end of the month 

 an abundance of air is indispensable, leaving the sashes and 

 doors open every mild night, that the plants may be inured 

 to the open exposure they will have in a few weeks. 



WATERING. 



As the season advances and vegetation increases, the 

 waterings will require to be more copious and more frequent. 

 Look over all plants minutely every day, and with judicious 

 care supply their wants. Those that are of a soft shrubby 

 nature, and in a free-growing state, will require a larger portion 

 at one time than those of a hard texture, which may only 

 want it every two or three days. The weather and situation, 

 in some instances, may require a modification of these direc- 

 tions. Plants in general will not suffer soon from being a 

 little dry as from being over-watered. The health and beauty 

 of the foliage of the plants may be much improved by syring- 

 ing them freely three evenings in the week, except in moist 

 weather, when it ought not to bo done. The ravages of many 

 insects also will be retarded, especially mildew and red spider, 

 which will be entirely destroyed. If the red spider is on any 

 of the plants particularly, take them aside evening and morn- 

 ing, and give them a good dashing with water through the 

 syringe. Where there is mildew, after syringing the plant, 

 dust it on the affected parts with flower of sulphur, and set 

 them for * few d.-sys w'aere they will be sheltered from the
