Somewhat heavy loam y are best for potting pine apples, for melons and strawberries, fruit trees in pots, &c., and may be used with the addition of manures only; but for ornamental plants a loam of a somewhat freer texture is preferable and more pleasant to work.
Edge of the heap of potting soil are spread over the crocks.
When, however, a hard-wooded plant has to be repotted, the case is different; it may stand without further potting for one year or two years or more, and therefore much more care is necessary.
The ball is to be set on the new soil just high enough that when finished the base of the stem may be somewhat below the pot-rim, and the space between the old ball and the sides of the pot is to be filled in gradually with the prepared compost, which is from time to time to be pressed down with a blunt-ended flat piece of wood called a potting-stick, so as to render the new soil as solid as the old.
The potting must be done very firmly, using turfy loam with which a little mortar rubble has been mixed.
