All plants grown under conditions such as these should have their pots plunged inside a larger and waterproof pot with the space between the two packed with some moisture retentive material such as peat.
If this material is kept constantly moist, but not soaking wet, this moisture will be absorbed by the plant pot as it is required. This moist material will also give off a surprising amount of humidity, normally wafting it upwards through the leaves of the plant above.
Alternatively plant pots can be stood on a tray or waterproof shelf, either plunged in peat again, or on a base of shingle or pea- sized pebbles. If this tray is kept constantly moist then the same beneficial results will be obtained.
Normally in most commercial greenhouses plants are grown on benches or shelving which is covered with a layer of shingle, sand, peat or ashes. This is kept moist and the plants benefit. It is possible to obtain simple automatic trickle irrigation equipment, similar to that used in so many commercial greenhouses, which will take care of plants in this fashion when they must be left for long periods, even the entire day.
But respiration rates are bound to be high, and unless spraying can be resorted to several times during a hot clay these rates will outstrip the speed with which plants can absorb moisture at their roots.
Simultaneously conditions are such that comparatively large plants in comparatively small pots are sure to dry out at the roots, sometimes at alarming speed, so we must make arrangements to see that the soil around the plant roots is kept as cool and as moist as possible.
