In ordinary cases the potting soil should be just so far removed from dryness that when a handful is gently pressed it may hang together, but may lose its cohesion when dropped.
This mode of potting does well for bulbs, such as hyacinths, which are either thrown away or planted out when the bloom is over.
Edge of the heap of potting soil are spread over the crocks.
In potting the well-established plants, and all those of considerable size, the soil should be used in a rough turfy state, not sifted but broken, and one-sixth of broken crocks or charcoal and as much sand as will insure free percolation should be mixed with it.
The potting must be done very firmly, using turfy loam with which a little mortar rubble has been mixed.
Begin to propagate greenhouse plants by cuttings; also coleuses by cuttings in heat, potting them off as soon as rooted.
