The tuberous-rooted begonias, which are every year becoming more popular, both as pot-plants, and for bedding out-of- doors, are the result of crossing several different species differing considerably in habit, and are easily cultivated. They are raised almost wholly from seed, and good strains in different colors may be obtained from any reputable seed firm. However, if one wishes to increase these plants by cuttings it can be done. Shallow boxes or seed-pans may be used in which to sow the seed about the beginning of February. They should be well drained and filled with a compost made up of equal parts of peat, leaf-mold and about a fourth of charcoal. As soon as the plants are large enough to handle, prick them out about 2 inches apart in the same soil as above, place them close to the glass, but always shaded from the bright sun, and in a moist atmosphere. When they have grown close together, transfer them to 3^-inch pots, the best soil to use from now on being a spent mushroom bed, adding about a fifth part of charcoal. A 6-inch pot is generally large enough for the first season, and when they are well established in these pots should be kept as cool as possible. A house facing north is the best place for them during the summer, and all the air possible may be admitted night and day. On no account allow these plants to suffer for lack of water until fall, when they will begin to show signs of ripening off. During their growing period, they may be stimulated by frequent applications of cow-manure water, and soot diluted in water, an ordinary handful to two and a half gallons of water; water three times with clean water, and alternately with the other two. When signs of ripening begin to show, gradually withhold water until the growths decay, and then place the pots on their sides under a bench in a greenhouse where the temperature keeps around 40°. Be sure they are in a position where water does not reach them. The tubers will be good for several years, but the best plants are in their second year. The plants may be started at intervals, having an earlier and a later lot. For bedding out in partial shade, these plants have no equals. Start the tubers in flats about the end of April, have the bed heavily manured and the soil level with the surface of the ground, as the roots run near the top of the ground, and consequently they have to be watered frequently. The top of the bed should be always moist, a mulching of well-rotted manure being of great assistance in retaining the moisture. Plant about a foot apart, all of one color, unless great care is exercised in blending the brilliant colors so that they do not clash.
