month look over tliem all minutely, and cut away any of the 

 small naked wood where it is too crowded, and cut all young 

 strong straggling shoots to the bounds of the tree, giving it 

 a round regular head. It is sometimes necessary to cut out 

 a small limb, but large amputations should be avoided. 

 Cover all large wounds with clay, turpentine, or beeswax, 

 to prevent the bad efiects of the air. 



OF REPOTTING PLANTS. 



Any of the plants enumerated in March under this head 

 may be now done according to directions therein given, and 

 which apply to all sizes. This is the proper period for repot- 

 ting the following : 



Calla, a genus'of four species. None of them in our col- 

 lections, and in fact not worth cultivation, except C. uEthi- 

 02yica, Ethiopian Lilj^, which is admired for the purity and 

 singularity of its large white flowers, or rather spatha, which is 

 cucullate, leaves sagittate. It is now called Richardia uEihi- 

 opica. The roots, which are tubers, should be entirely 

 divested of the soil they have been grown in, breaking off any 

 small offsets, and potting them wholly in fresh earth. When 

 growing, they cannot get too much water. The plant will 

 grow in a pond of water, and withstand our severest winters, 

 provided the roots are kept at the bottom of the water. 



Cyclamen. There are eight species and six varieties of 

 this genus, which consists of humble plants with very beau- 

 tiful flowers. The bulbs are round, flattened and solid, and 

 are peculiarly adapted for pots and the decorating of rooms. 

 C. coum, leaves almost round; flowers light red; in bloom 

 from January to April. C. iJ&rsicum, with its four varieties, 

 flower from January to April; color white, and some white 

 and purple. C. hedersefoliumy Ivy-leaved ; color lilac ; 

 .here is a white variety; flowers from September to De- 

 cember. C. Europseum, color lilac, in bloom from August 

 to October. C. Neapolitcumvi, flowers red; in bloom from 

 July to September. These are all desirable plants. When 

 the foliage begins to decay, withhold the accustomed sup- 

 plies of water, keeping them in a half dry state; and, when 

 growing, they must not be over-watered, as they are apt to
