The standard clay, porous flower pot, employed by the commercial grower, does not produce good plants in dwelling houses. In order to use this pot successfully, it must be kept on a bed of moist material so that the evaporated water may be replaced from outside the pot instead of from the moisture within the pot. Thus, a pot may be porous or vitreous witliout any injury occurring to the plant if cultural practices are adaj)ted to the type of pot. The non-porous pot is adaptable to the requirements of house and office culture of ornamental plants, and may' even be used by tlie commercial grower with special advantage if plants are to be shipped. The porous pot may be made non-porous by filling tlie pores with paint, or similar preparations. The non-porous containers may be made of water- proofed fibers, glass, any vitreous material, or any synthetic substance that can be poured into a mould or stamped out, as metal. It should be kept in mind, however, that there should be no soluble chemical in the substance of the pot that will be harmful to plants. Should there be decomposable mater- ials in the pot, nitrogen deficiency would probably Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Massachusetts Agricultural Experiment Station.
