ROSES IN POTS. 



and this only from the top in still mild weather. I have 

 found the plants more liable to suffer from the admission 

 of cold air, even on sunny days, than from a temperature 

 of 100. Whilst they do not appear to suffer from the 

 latter high temperature, the too free admission of air 

 early in the season will cause the young leaves to curl up 

 and eventually drop off in numbers. The plants should 

 be kept as near the glass as possible, and if leaves or tan 

 can be procured readily to plunge them in to secure a 

 gentle bottom heat, less fire-heat will be necessary, and 

 they will repay the extra trouble. 



It is difficult to lay down any precise rules for water- 

 ing ; this the judgment must direct ; the plants require to 

 be kept tolerably moist, and the water should be carried 

 into the house some time before required for use, both in 

 watering and syringing, that it may become of a milder 

 temperature. The description of plants I prefer, are for 

 the most part, those worked on the Dog-rose, from which 

 it is necessary to keep all suckers removed ; and as most of 

 these spring from under the soil, I have found that by clasp- 

 ing the tops firmly between the thumb and finger when in a 

 young state, and pulling them steadily, they may be drawn 

 out from the base, thus effectually removing them as they 

 appear without disturbing the roots, The Grub which 

 attacks Roses so generally out of doors, frequently finds 

 its way into the forcing house, and should be carefully 

 sought after and removed by hand. The Green Fly, though 

 more under our command here, is not less troublesome ; 

 as soon as any are seen, the house should be fumigated 

 with tobacco to destroy them, and this continually re- 

 peated through the season as they re-appear. The Red 

 Spider and Mildew will sometimes infest the plants, for 

 which sulphur is the generally acknowledged remedy. 

 Dusting it on the leaves after syringing is an easy method 

 of applying it. From the Red Spider, however, in a house 

 with a moist atmosphere, there is not much to fear ; and 

 it is perhaps as well to remove plants inclined to Mildew
