Greenhouse. To turn all the plants out in "the first week in May," with- 

 out reference to any contingency — this should not be; all plants should be 

 gradually inured to the open air — the ventilators and sashes should be kept 

 open as much as possible, yet by degrees — sudden changes of temperature 

 engender mildew, and a species of consumption fatal to many plants — the 

 hardiest things should be placed out first, in a somewhat shaded spot, and if 

 possible on a bottom of coal ashes to keep out worms — Azaleas and Rho- 

 dodendrons, Daphnes and Camellias may go out when their growth is finished 

 ^-no spot will be too shaded, provided they can get an abundance of air all 

 around. If plants are well rooted, and have not been repotted, they should 

 be so before setting out, as they will, otherwise, suffer at times for want of 

 water. It is objectionable to turn out everything, leaving the greenhouse 

 for the season like a lumber loft — such as will stay in advantageously should 

 be left, and the idea is becoming prevalent that cape and hard wooded things 

 are better in than out. 



Abutilons, Habrothamnuses, and Oestrums, indeed many similar plants, 

 if taken out of their pots, turned out into the open border, and lifted and 

 repotted early in the fall will make fine growths and do well — as fast as 

 Hyacinths in pots are done flowering, turn them out into beds as recom- 

 mended last month — -Calceolarias should be kept in the coolest part of the 

 house, and have a good supply of water, they frequently die after flowering 

 — cuttings of desirable kinds should be taken from them now, and if they 

 show signs of flowering before fall, dont allow it — Cinerarias should receive 

 the same attention, as they also die out after flowering — as soon as the 

 Chrysanthemums, planted out as recommended last month have shot forth, 

 take cuttings for next season's show — they strike very readily in sandy soil, 

 in a somewhat moist and shady situation — Dahlias need not be put out be- 

 fore the second or third week in May — they do not like the scorching heat 

 of summer, and if put out early become stunted and do not flower till later. 

 Pelargoniums should have all the light possible till they begin to open their 

 flower buds, when they should be somewhat shaded and kept cool; by this 

 the flowers are rendered finer, and last longer — Everblooming roses, grown 

 in pots, should be pruned in a little after their first flowering, kept a little 

 drier for a week or so, then repotted, and place where desired out of doors 

 — they delight in a rich loamy soil, and are benefitted by manure water 

 while growing ; those who have not a collection should begin — there is no 

 finer class; six of the best for pot culture may be Souvenir de la malmaison, 

 salmon white; Devoniensis, pale lemon; Hermosa, rose; Agrippina, crim- 

 son; Lyonnais^ pink; and as a free blooming white, CeU.
