20 THE FLORAL WORLD AND GARDEN GUIDE. 



When the flowering season is over, return them to the stove, and 

 set them in the coldest part ; reduce the water by degrees until the 

 roots are in a state of rest, for three or four months at least lie 

 careful not to over-dry them, as by such practice I have often found 

 them not to break the next season. 



THE TKEE-ONION. 



HE tree- 

 onion is re- 

 man kable for 

 reproducing 

 itself by off- 

 sets, which it bears at 

 the top among, or in- 

 stead of, the umbel of 

 flowers. They should 

 be planted at once, or as 

 soon as the weather per- 

 mits. The ground should 

 be liberally manured, 

 and trod firm. Choose 

 for planting the largest 

 of the top bulbs, which 

 are generally over an 

 inch in diameter. Press 

 these down firmly in a 

 line about six inches apart, and the same 

 distance between the rows. Cover them 

 over with three or four inches of charred 

 rubbish, ashes, or sand, and put stakes at 

 about a yard apart on each side of the 

 rows, connecting the stakes with hazel- 

 rods, laths, wires, or cord, to give support 

 to the stems when they get top-heavy with 

 their curious crop of onions at the summit 

 of each. In good soil, and liberally treated 

 — as watering in dry weather — well sup- 

 ported, and kept clean from weeds, they 

 will increase every year twenty-fold. If 

 the ground bulbs are well ripened, they 

 may be planted instead of the largest from 

 the top cluster.
