and Citron Trees. By Mr. James Mean. 297 



required for the recovery of a luxuriant foliage, as they, par- 

 ticularly the Orange trees, are very slow in producing new 

 leaves. 



In regard to the necessity of thinning the fruit, lest the 

 trees should exhaust themselves, it appears to me to depend 

 on the state of the trees ; if they are flourishing, I never 

 observed that it was at all required, either here or at Bromley 

 Hill, where the Orange trees belonging to the Right Honour- 

 able Charles Long are very fine, and loaded with peculi- 

 arly large fruit. 



The house in which the plants are kept is built with brick 

 piers, and had formerly a tiled roof, which was replaced a 

 few years since with one composed entirely of glass, and a 

 new flue was carried round the two ends and front. The 

 house is 18 feet high and is devoted entirely to Orange, 

 Lemon, and Citron trees ; before the alteration it was very 

 close and damp. I consider the prevention of damp, as 

 much as the exclusion of cold, essential to the perfection 

 of the plants ; the house is therefore always well warmed in 

 winter by the flue. 



I find Lemon and Citron trees do better than Orange trees ; 

 they are in all respects hardier, and consequently preferable 

 to plant in the borders of the house for the purpose of being 

 trained to trellis on the walls.
