ous-rooted perennials. To this latter 

 belongs S. tuberosum, the potato. The 

 annuals are increased by seeds; the 

 other species by seeds, cuttings, or 

 tubers. Light rich soil suits them all. 



Green-house evergreen shrubs. Ripe 

 cuttings taken off at a joint. Turfy 

 loam and sand.

Soil and Situation. — They thrive best 

 in any garden soil that tends to light- 

 ness rather than tenacity, and is not 

 too poor. The situation must be open. 



Propagation. — The rumexes are pro- 

 pagated by seed, and all of them by 

 parting the roots, both which modes 

 may be practised from tha middle of 

 February until the same period in May, 

 and by the latter also in September 

 and. October. The finest plants are 



SOLLYA. Three species. Green- raised by seed, but those from portions 



of the roots are soonest in production. 



The seed is best sown in drills, six 

 or eight inches apart, and half an inch 

 in depth. When two or three inches 

 high, the seedlings must be thinned to 

 three or four inches apart, and those 

 removed, if required, pricked out at 

 similar distances. In September or Oc- 

 tober, or in the March and April of the 

 succeeding year, they may be removed 

 into their tinal stations, in rows twelve 

 inches apart, each way, or, if the 

 French, eighteen inches. The only 

 attention they require down to this 

 state of their growth, is to be kept clear 

 of weeds, and to have water given in 

 moderate quantities after each removal, 

 until established. 



When divisions of the root are em- 



house evergreen climbers. Cuttings.

It is an excellent manure for peas, 

 onions, carrots, and probably all garden 

 crops. An excellent liquid maiiure is 

 soot mixed with rain water, in the pro- 



portion of one tablespoonful of soot 



to a quart of water, for plants in pots ; ployed, they must be set at once where 



but for asparagus, peas, &c., six quarts 

 of soot to a hogshead of water. It 

 must never be applied to plants in a 

 state of rest. It succeeds admirably 

 with bulbs. — Gard. Chron.

they are to remain, at the final dis- 

 tances above mentioned ; and the same 

 attention paid in weeding and watering 

 them. Established plants must in a 

 like manner be kept constantly free 

 from weeds. In summer, as thoy run 

 up to seed, the stalks must be cut down 



duoustrees; stove and green-house ever- as often as is re(]iiired, to encourage 



green shrubs and trees. The latter in- 

 crease by cuttings, the former by divi- 

 sion. S. chinensis and S. japonica,

 seeds. Light loamy soil.

the production of leaves. In autumn 

 and spring, the surface of the ground 

 should be gently stirred, and in the 

 former season, a little manure, or in 

 preference, a similar proportion of de-. 

 cayed leaves, turned in. Some garden- 

 ers raise fresh seedlings annually, but 

 a fresh plantation is seldom necessary 

 oflener than every fourth year ; before 

 which, however, it must be made, if the 

 plants dwindle or produce diminutive 

 leaves.
