Some of these being hardy, thrive in the open ground with but little care or trouble, others requiring very great attention, protection from exposure, and shelter from the heat of the sun, and the intensity of its rays; which should therefore have a particular portion of the plant-shed assigned to them, such being inhabitants of the green house in colder climates, and the reason of assigning them such separated part of the chief house, or what is better perhaps, a small house to themselves, is that in culture, treatment, and other respects they do not associate with plants of a different character.

One great obstacle which the more extensive culture of bulbs has had to contend against, may be found in that impatience that refuses to give attention to what requires from three to five years to perfect, generally speaking people in India prefer therefore to cultivate such plants only as afford an immediate result, especially with relation to the ornamental classes.

Propagation.—­The bulb after the formation of the first floral core is instigated by nature to continue its species, as immediately the flower fades the portion of bulb that gave it birth dies, for which purpose it each year forms embryo bulbs on each side of the blossoming one, and which although continued in the same external coat, are each perfect and complete plants in themselves, rising from the crown of the root fibres:  in some kinds this is more distinctly exhibited by being as it were, altogether outside and distinct from, the main, or original bulb.  These being separated for what are called offsets, and should be taken off only when the parent bulb has been taken up and hardened, or the young plant will suffer.

Some species of bulbous rooted plants produce seeds, but this method of reproduction, can seldom be resorted to in this country, and certainly not to obtain new kinds, as the seeds require to be sown as soon as ripe.

Soil, Culture, &c.—­For the delicate and rare bulbs, it is advisable to have pots purposely made of some fifteen inches in height with a diameter of about seven or eight inches at the top, tapering down to five, with a hole at the bottom as in ordinary flower pots, and for this to stand in, another pot should be made without any hole, of a height of about four inches, sufficient size to leave the space of about an inch all round between the outer side of the plant pot and the inner side of the smaller pot or saucer.

This will allow the plant pot to be filled with crocks, pebbles, or stone chippings to the height of five inches, or about an inch higher than the level of the water in the saucer, above which may be placed eight inches in depth of soil and one inch on the top of that, pebbles or small broken brick.  By this arrangement, the saucer being kept filled, or partly filled, as the plant may require, with water, the fibres of the root obtain a sufficiency of moisture for the maintenance and advancement of the plant without chance of injury to the bulb or stem, by applying water to the upper earth which is also in this prevented from becoming too much saturated.  Light rich sandy loam, with a portion of sufficiently decomposed leaf mould, is the best soil for the early stages of growing bulbs.
