JULY. 



may be cleared whenever the principal 

 part is cut. The bottom heat must be 

 freshened up by the addition of fresh 

 material, and made ready for plunging 

 the new stock of plants as they are placed 

 in their fruiting pots. 



Repairing House. In the meantime 

 advantage should be taken of putting the 

 house in repair, if requisite, and the heat- 

 ing apparatus in a state of efficiency, as 

 no such favourable opportunity will occur 

 again for a twelvemonth. 



Ventilation. As the houses are cleared 

 of their fruit, and the wood is ripened, it 

 will be much benefited by having the 

 lights off, and by being freely exposed 

 to the atmosphere for a time. Air must 

 be given in abundance by night as well 

 as day, and the necessary stopping of 

 lateral growths and thinning of the fruit 

 in the last house proceeded with. Watch 

 for mildew, which is caused by excess of 

 moisture, and must be checked by the 

 sulphur remedy, which consists in dusting 

 all affected parts with sulphur in the form 

 of a fine dry powder. The disease shows 

 itself in spots or blotches on the leaves, 

 and a dirty, unwholesome thick dust or 

 mould, which spreads itself over the 

 branches and berries. This, as it has 

 been said, is the consequence of an excess 

 of moisture; too little moisture, on the 

 other hand, will produce red spider, which 

 may be checked by fumigation with sul- 

 phur, or prevented, which is better, by 

 maintaining a suitable moist condition of 

 the air of the house, a happy medium, in 

 fact, between insufficiency of moisture and 

 a superabundance of it. 



Vinery. Shading, <5rV. Ripe grapes, 

 if required to be kept, must be shaded 

 during hot sun, to prevent their becoming 

 shrivelled. The Muscat, Sweetwater, and 

 Frontignan, having tender leaves, are most 

 liable to burn, either from bad glass or 

 imperfect ventilation; in which case they 



must be well watched, as the injury done 

 to the foliage not only affects the present 

 crop, but the succeeding one as well. 

 Any heat given now should be given 

 during the day, in order to their getting 

 well forward before the season gets too 

 far on. Under this treatment they all 

 keep longer and have a finer flower, keep- 

 ing the outside borders of the late crops 

 watered and well mulched. 



Vines in Pots. Vines in pots intended 

 to fruit next season should now be well 

 supplied with manure water, to swell out 

 and perfect their buds. 



July. Hothouse, Work in. 



Such stove plants as are intended to 

 flower in the winter, as justicias, Eranthe- 

 mum pulchellum, euphorbias, jasmines, 

 &c., should be looked to. Many of these 

 things require to be kept in small pots, 

 and should be watered with liquid manure 

 to grow them on without getting into too 

 large pots. Encourage plants now estab- 

 lished by using liquid manure. Young 

 plants growing into specimens will require 

 constant stopping and trying to get them 

 into proper form. In shifting for the 

 season, many conservatory plants will now 

 be in the open air ; but some of the New 

 Holland, such as Boronia pinnata and B. 

 serrulata, still require a little heat and 

 pretty free stopping to insure handsome 

 plants. 



Achimenes, Clerodendrons, Gloxinias, 

 &c. Achimenes, gloxinias, &c., out of 

 bloom should be removed to a pit to 

 ripen their bulbs. Clerodendrons, &c., 

 in the same way may be transferred to 

 vineries, or any place where there is a 

 dry cool atmosphere. 



Azaleas. Chinese azaleas should be 

 turned out. Unlike camellias, they re- 

 quire full exposure to sun and air, and 

 should be placed in an open situation, 

 that their wood may become thoroughly
