earth, but before they become brown and woody; that
is, while they are still white and succulent--"working roots," as the
florists term them.

ashes, etc., at the bottom, to prevent moisture from settling in the
soil and souring it]

The shift, as a general rule, should be to a pot only one size larger,
that is, from a three to a four, or a four to a five.

Remove the plant from the old pot by holding the stem of the plant
between the index and middle finger of the left hand, and with the right
inverting the pot and rapping the edge of the rim sharply against the
edge of the bench or table.

Before putting the plant into the new pot, remove the top half inch of
soil and gently loosen up the lower half of the ball of roots, if it is
firmly matted.

Put soil in the bottom of the pot to such a depth that when the ball of
roots is covered with half an inch or so of new soil, the surface
thereof will still be about half an inch below the rim of the pot. Hold
the plant in place with the left hand, and with the right fill in around
it, making the soil firm as before. Water and care is the same as after
the first potting.

Pots four inches or over in size should be crocked to make certain of
sufficient drainage. The best material to use is broken charcoal, in
pieces one-half to an inch in diameter. Pieces of broken pots, cinders
or rough pebbles will do. Be sure that the drainage hole is not covered;
if pieces of pots are used, put the concave side down over the hole, as
illustrated facing page 41. The depth of the drainage material, or
crocking, will be from half an inch to three inches, according to the
size of the pot. Over this rough material put a little screenings, leaf
mould or sphagnum moss, to prevent the soil's washing down into it. Then
fill in with soil and pot in the regular way.

The time for repotting house plants is at the beginning of their growing
season. It varies, of course, with the different kinds. The great
majority, however, start into new growth in the spring and should be
repotted from the mid
