As the season has now arrived when plants under protection in pits, frames, or other structures, not artificially dried or ventilated, are injured by damp, the following plan is submitted to remedy the evil:
Procure some quicklime from the works as fresh as practicable after being drawn from the kiln, and place pieces of it on plates, saucers, pans, tiles, slates, or in garden pots, in different parts of the pits, etc. among the plants in pots, until it becomes slacked by absorbing the damp, then remove it; and, when necessary, use another supply. This year I had some plants in a hotbed-frame that were damping off; I was induced to try the effect of fresh quicklime to check the evil, and the result was favourable.
I was led to this application from having for several years used successfully quicklime to dry up the floors and fittings of premises liable to be flooded, by placing lime on the floors, near the walls, and in lockers, and other fittings, that were saturated by water.
For the first trials with delicate tender plants, caution will be necessary not to use too much lime.
I am confident that this plan will be found very beneficial in many cases, and prove a simple, useful, economic one, for the lime will not be injured for many other purposes.
