When transferred, each
Onion is allowed a space of three inches. The boxes are kept in a
greenhouse, as near the glass as possible, in a temperature of about
50 deg.. After sowing, very little water is given; but when transplanted,
finish with a sprinkling from a fine rose. Every morning the plants will
require spraying, but this must never be done at night or damping off
may follow. All through their time in the greenhouse it is important to
keep the boxes near the glass. Towards the end of March remove to cold
frames, keeping the lights rather close for a few days, but gradually
giving more air until the lights can be taken off for a short time
daily.

In the south, about the middle of April is generally a suitable time for
transplanting to open beds, but in the event of a cold east wind
prevailing a brief delay is advisable and it is always an advantage to
plant out on a dull day or in showery weather. Space the rows twelve to
eighteen inches apart, and allow about fifteen inches between plants in
the rows. In the actual work of transplanting take care to insert only
the fibrous roots in the soil. To bury any portion of the stem results
in thickened necks. Finish with a dusting of soot over the entire bed,
including the Onions, and then well spray from a fine rose to settle the
soil around the roots. Until the plants are established continue the
spraying daily. After the middle of May renew the dusting of the bed
with soot and repeat at fortnightly intervals. About the 20th of June
feeding the Onions must commence. Peruvian guano and nitrate of soda are
both excellent, but these powerful artificials need using with
discretion, or the crop may be scorched instead of stimulated. It is
often safer to employ them in liquid form than dry, and ten ounces of
either, dissolved in ten gallons of water, will suffice for thirty
square yards. Use the two articles alternately at intervals of ten days
and cease at the end of July. If continued longer, some of the finest
bulbs will split. The use of soot can, however, be regularly maintained.
Should bulbs be required for autumn exhibition carefully lift them a
week or ten days in advance of the show date. This has the effect of
making the bulbs firm and reducing the size of the necks.

Supposing an attack of mildew to occur, a dusting of flowers of sulphur
will prove effective if applied immediately the disease appears.
