The pots should be plunged in a cold frame and protected from frost, and about May may be removed to a sheltered and moderately shady place out-doors to remain till they flower, when they may be removed to the greenhouse.
Sow early peas in a cold frame for transplanting.
Roses, carnations, camellias, azaleas, pelargoniums and the hardier sorts of plants will do better if placed in a cold frame or pit until the middle of November than they would in an ordinary greenhouse.
Leave the potted cuttings in a closed cold frame during winter and transplant next spring.
Place the pot in a cold frame or cover with a 15cm layer of sharp sand or peat and leave somewhere cold outside.
