Give them alfo frelh air, by raifmg the glafTes every 



day. 



Keep up the warmth of the bed by moderate linings. 



According as the plants rife in height, the frame muH 

 be raifed ; and, provided there be a moderate warmth 

 continued in the beds, and the pots kept moift, the plants 

 will, in two or three months, be a foot and a half, or 

 near two feet high. 



Inarching may ftill be performed on orange and lemon- 

 trees, where required ; and it may be done any time in 

 the month, obferving as directed in April and March. 



The Hot-House. 



THE principal care of the hot-houfe now Is to keep 

 the plants clean, and to fupply them duly with the 

 two necelTary articles of water and fre(h air, 



Pine-Apples. 



The pine-apple plants in general, will now require a 

 moderate refreihment of water every four or five days ; 

 and either in a morning from eight to nine or ten o'clock, 

 or about three or four in the afternoon is the beft time of 

 the day to do it. 



In watering thefe plants, take particular care not to 

 apply too haftily, nor to give them too great quantities at 

 any one time ; for that would not only damp the heat of 

 the bark, but would alfo loofen the plants in their pots, 

 chill the roots of them, and prove of very bad confe- 

 quence. 



Frelh air is the next very needful article to be conlider- . 

 ed, and the plants fliould now be allowed a confiderable 

 Ihare of it, every warm funny day. 



Slide fome of the glafTes open a little way, every hot 

 day, about nine o'clock ; and, as the heat of the day in- 

 creafes, continue to open them fomewhat wider, that a 

 proportionable fhare of frefh air may be admitted ; and 

 fhut the giafles again about three or four o'clock. 



Where the young pine-plants, that is to fay, the crowns 

 and fuckers of laft year, were not ihifted into larger pots 

 the former month, it Ihould now be done.
