period of their making their wood, as rhodo-

 should be used. 



Removing the plants from the greenhouse during 

 summer. — We have already remarked, that want 

 of sufficient room led, in the first instance, to 

 this practice, and habit with many has continued 

 it. There is no doubt many of the hardier kinds 

 of plants may be thus treated with no apparent ill 

 effect, if they are not set out before the beginning 

 of June, and taken in by the end of September, 

 The more tender and choice plants should not 

 be so treated. The smaller ones, that they may 

 enjoy more air, light, and space, should be 

 placed, towards the middle of May, in cold pits, 

 and covered with glass, which, during the heat 

 of summer, may be removed, but kept ready, at 

 the same time, to be replaced during cold nights, 

 and when heavy rains are falling. We have re- 

 peatedly stated that, as all plants experience a 

 summer and a winter season naturally, it is only 

 consistent with reason that they should do so 

 in an artificial state. Now, keeping them in a 

 moderately warm greenhouse during winter, and 

 placing them in the open air, in our cold climate, 

 during summer, is assuredly not fulfilling these 

 conditions. The rule should be, keep them cool 

 during winter, and warm during summer, which 

 is, or rather ought to be, their season of growth, 

 flowering, and maturing their wood and buds for 

 another season's growth. This is a matter of 

 much greater importance in Scotland than in the 

 south of England, where many of them would be 

 too hot if kept under glass during the warmest 

 months of summer. Such as are to be placed 

 out of doors should be, so far as is consistent 

 with the welfare of those of more delicate habits, 

 for a week or two before removal exposed to a 

 greater amount of air, by copious ventilation; 

 and on their being taken out, they should be 

 placed for a few days in a rather shaded and 

 sheltered situation, and afterwards placed, not; 

 as is usually the case, under the shade of trees, 

 or behind walls, but fully exposed to the sun, that 

 their growth may be early made and thoroughly 

 ripened before the end of the season. The plants 

 themselves will stand all the sun we have, but 

 the roots are liable to injury if the pots are not 

 protected. Plunging them in the soil prevents 

 this; but, on the other hand, the roots, being 

 deprived of air, and being liable to become 

 saturated with moisture, suffer equally, but from 

 a different cause. They should be, therefore, set 

 upon a dry level floor, rendered impervious to 

 worms, and the pots surrounded with moss, or 

 some other wet-absorbing yet heat-resisting me- 

 dium; or they may be set within pots of a larger 

 size, and the space between them filled with 

 moss. They should be neatly supported to pre- 

 vent their being blown over; and this is best 

 effected by fastening long laths to neat uprights 

 of wood, and securing the plants to the former. 

 They should be allowed ample space, and exa- 

 mined night and morning to see that they do 

 not suffer from lack of water. The middle of 

 May in the south, and the beginning of June in 

 the north, is the proper time for setting the 

 plants out ; and in the former case they may 

 remain, in most seasons, till the first or second 



week in October; but, in the latter, the end of 

 September is as late as they can be safely trusted 

 out, unless protected under a portable canvass 

 covering. 



During summer those left in the house should 

 be set thinly, abundantly supplied with water, 

 and ventilation given to a greater extent than 

 during any other part of the year. In lean-to 

 houses they should be frequently turned round, 

 that all sides of the plants may enjoy the effects 

 of light and sunshine. Partial shading is only of 

 use to continue the blooming period, the plants 

 otherwise requiring all the sunshine we have; 

 and whatever shading is used, it should be of so 

 thin a material that the rays of light may be in- 

 tercepted as little as possible. 



Training. — During summer the plants should 

 be frequently gone over, and all over-luxuriant 

 and useless shoots removed; others topped, to 

 cause a sufficient number of shoots to be produced ; 

 such as require it, neatly trained to supports; but 

 plants so treated as to be able to maintain their 

 perpendicular without such assistance always 

 look best. Some, however, of slender growth, 

 do require support, and all scandent or climbing 

 plants do. Training as an art in culture is not, 

 in general, well understood, and hence we have 

 plants trained in the most stiff and formal man- 

 ner possible, while others are twisted, and con- 

 strained to forms of which we have no similar 

 examples in nature. Every plant should be 

 trained or made to assume an appearance as 

 near as possible to that of its natural habit.
