MAY. 



All the plants will be able to withstand exposure, in the 

 general state of the seasons, about the tenth of the month. 

 Begin about the first to take out the hardiest, such as Lau- 

 restinus, Hydrangeas, Roses, Primroses, Polyanthus, &c, and 

 thus allow the others to stand more free and become hardened 

 to exposure. The reason that plants are so often seen brown, 

 stunted, and almost half dead during summer, is from the 

 exposed situation they are placed in, with the direct sun upon 

 them, and too frequently from being so sparingly watered. 

 There are no shrubby plants cultivated in pots that are bene- 

 fited by full exposure to the hot sun from this period to Sep- 

 tember. A northeastern aspect is the best for every plant 

 except Cactus, Aloe, Mesembryanthemum, and such as go 

 under the name of succulents, which may be fully exposed to 

 the sun, but not to long and continued rains. Where there 

 are only a few plants, they should be conveniently placed, to 

 allow water from a pot with a rose mouth to be poured fre- 

 quently over them, which is the best substitute for the syringe. 

 Daphne, Coronilla, Fuchsia, Camellia, Primrose, and Poly- 

 anthus, do not agree with bright sun through the summer. 

 There has been a general question what is the cause of the 

 death of so many of the Daphne odora. It may be observed 

 that the first place that shows symptoms of decay is at the 

 surface of the soil, and this takes place a few weeks before 

 there are evident effects of it. The cause is from the effect of 

 heat or sun and water, acting on the stem at least. If the 

 soil is drawn in the form of a cone round the stem, to throw 

 off the water to the edges of the pot, that the stem may be dry 

 above the roots, mortification does not take place, neither do 

 they die prematurely when thus treated. For further remarks, 

 6ee Gre^u-house this month.
