Towards the end of this month, or quite the beginning of next, it is most important to erect shelters under walls or trees, where the sides can be protected from wind and the top covered up on cold nights, as now is the time it is so important to clear out greenhouses, both for the sake of the hardier plants that are going out, and the more special ones that remain inside. When they are moving, feeling the spring in all their fibres, that is the time they begin to get weak and drawn up if not given room and air. This is especially the case with the large old Geraniums that are in the greenhouse, Carnations, Abutilons, not to mention all the forced things that have done flowering. Putting them out under these shelters hardens them off well before they are planted out in the open. Nothing is more distressing to a real plant-lover than to see bulbs and Spirĉas and Azaleas lying about untended, just after they have done their work so valiantly for us early in the year. If a plant is not worth care, it is not worth keeping. Throw it away at once where it goes to make food for future generations, and the pot is useful when many pots are wanted. As I said before, but remind now, pieces of corrugated iron come in most usefully in making these temporary pens and shelters. For some plants a sunk pit with a raised rim of brick or turf answers well. On this the sheets of iron are laid at night.
