Circumposition differs from layering, only that in this the shoot to be rooted is bent down to the soil, whilst in circumposition the soil is placed in a vessel and raised to the shoot. There are pots called layering pots made for this practice, and differing from the common garden pot, only by having a section about an inch broad cut through one side, and to the centre of the bottom, for the admission of the shoot or branch.

M. Foulup employs "small tin cases of a conical form, like the upper part of a funnel, two and three-quarter inches in length, and two and a sixth inches in width at top, narrowing towards the lower part till only sufficient room is left for the introduction of the shoot or branch intended to be propagated. These cones are supported on rods, to which they are secured by wire. Commencing with the central branches, the leaves are taken from the parts which the tin is intended to inclose; the branch is cut two-thirds through as in layering, and being enclosed by the funnel, the latter is well packed with moss. Moisture necessary for favouring the emission of roots is supplied by means of a bottle, from which the bottom is struck off, and the neck furnished with a cork, perforated so as to admit a small pigeon's feather or bit of wool to form a syphon, by means of which the moss is kept in a proper state of moisture. Hard-wooded plants are propagated in this way from the middle of May till the end of June; and the branches are sufficiently rooted to be taken off by the end of September. It is, however, necessary in all cases, to ascertain whether the branches are sufficiently rooted previously to their being separated.

This is easily done by opening up the edges of the tin; when the branches are found to be sufficiently rooted they are potted off without removing the moss by which the roots are surrounded. Being moderately watered, they are immediately placed under glass on a slighthot-bed, and kept shut up for a fortnight. They are then gradually exposed, and afterwards placed in the shade of large trees, so that only half the rays of the sun shall reach them." - Gard. Chron.
