being to prick out the most forward plants on another mild bed as
soon as they are large enough to be lifted, and to make a succession
from the same seed-bed as the plants advance to a suitable size.

The third and last sowing may be made in the second week of April, in an
open border, on rich light soil, and should have the shelter of mats or
old lights during cold weather. From this, also, there should be two or
three prickings out, the first to be transferred to a bit of hard
ground, covered with about three inches of rich mulchy stuff, in the
warmest spot that can be found, and the last to a similar bed on the
coldest spot in the garden. In the final planting the same order should
be followed. The result will be a prolonged supply from one sowing, and
the first lot will come in early, though sown late, if the plants are
kept growing without a check, and receive thoroughly generous culture.

==The planting out== is an important matter, and each lot will require
separate treatment, subordinate to one general and very simple plan.
Celery must have rich soil, abundant moisture, and must be blanched to
make it fit for table. There are various ways of accomplishing these
ends, although they differ but slightly, and common sense will guide us
in the matter. For the earliest crops the ground must be laid out in
trenches, with as much rich stable manure dug in as can be afforded. To
overdo it in this respect seems impossible, for Celery, like
Cauliflower, will grow freely in rotten manure alone, without any
admixture of loam. The trenches should be eighteen inches wide at
bottom, ten inches deep, and four feet from centre to centre, and should
run north and south. The plants are to be carefully lifted with a
trowel, and placed six to nine inches apart in single or double rows,
and should have water as planted, that there may be no check. In a cold
soil and a cold season the trenches may be less in depth by two or three
inches with advantage. If dry weather ensues, water must be given
ungrudgingly, but earthing up should not commence until the plant has
made a full and profitable growth, for the earthing pretty well stops
the growth, and is but a finishing process, requiring from five to seven
weeks to bring the crop to perfection. The second lot can be put out in
the same way, and other plantings may follow at discretion; but as the
season advances the trenches must be less deep.
