May.] HOT-HOUSE OF BRINGING OUT, ETC. 177 



tea, Z. tenuis, Z. integi ifblia, are the most showy that belong 

 to the hot-house. The whole genus is frequently kept in 

 this department. They are all plants of a slow growth, and 

 the beauty is entirely in the pinnated fronds, with from ten 

 to forty pairs of leaflets. The pots must be well drained 

 (Soil No. 11.) 



Those genera of plants which we have enumerated under 

 the head of repotting in this or next month, are composed of 

 the finest hot-house plants that have come under our observa- 

 tion. There are perhaps a few of 'hem that are not to be 

 found in the United States, or even on our continent; but the 

 great object in a choice collection of plants, is to have the 

 finest from all parts of the known world. There are many 

 plants whose nature does not require much support from soil, 

 which is frequently observed in those that are mentioned. 

 And there are many hundreds of plants desirable for beauty, 

 ornament, and curiosity, which would take volumes to specify 

 and describe. In fact, every year brings many new things, 

 and frequently both new and splendid, either in flower, fruit, 

 or foliage. 



We have previously observed, that plants ought not to be 

 flooded with water when newly potted, as it saturates the soil 

 before the roots have taken hold of it; and that the best 

 draining for pots is small gravel or pot-shreds broken fine. 

 We wish it to be understood that, when plants are repotted, 

 any irregular branch or shoot should be lopped off that can- 

 not be tied to advantage. And repotting may take place 

 either before or after the plants are exposed to the open air, 

 according to convenience. 



OF BRINGING OUT THE HOT-HOUSE PLANTS. 



When the hot-house is very crowded with plants, the best 

 method to have them exposed without danger is to take out 

 those of the hardiest nature first, that have no tender shoots 

 upon them, thereby thinning the house gradually. This may 

 be done from the sixteenth to the twentieth of the month, 

 which will admit of a free circulation of air among those that 

 remain. All may be exposed from the twenty-fourth to the 

 twenty-eighth of the month. This is a general rule, though 

 in some seasons there may be exceptions. Having previously
