Watering-Pots
These, in various sizes, are requisite where there are many kinds of plants to be kept watered. For trees of all kinds, shrubs, outside garden crops, &c., the ordinary kind, with coarse rose, is well adapted, but the use of the rose is not always necessary. A pot holding from twelve to sixteen quarts is quite large enough for carrying and managing when full; the latter capacity being an extreme limit. Pots of smaller sizes are necessary for watering indoor plants, and these are better managed when the spouts are made longer in proportion than in the larger sizes. Sizes each holding two, three, four, five, and six quarts of water are adapted for use with long spouts; these prove most serviceable where plants have to be reached at a considerable distance from the person who is watering. It is sometimes an advantage to have the end of the spout bent downwards, at about a right angle, where the rose is fixed, as the water runs without lifting the can up so high. For watering beds, pots, or pans, where small seeds have been sown, a very fine rose is necessary, and it should fit the spout so that all drip is prevented: this is best insured by having the rose made of brass, so that it can be readily screwed on or taken off as desired. If the same thread is used, several roses, perforated to various degrees of fineness to suit the plants or seeds that are watered, can be employed for screwing on a can Watering-pots specially intended for Strawberries in spring are not furnished with a cross handle over the top; they hold about two quarts of water, and are provided with long spouts for the purpose of watering the plants referred to, when situated rather closely together, and on shelves near the glass. Watering-pots are usually either japanned, painted red or green, or galvanised in a similar way to ordinary cisterns. If the whole surface is properly galvanised inside and out, there is no danger of rusting, and Watering-pots made of galvanised iron are very strong and durable.
WATER PLANTS. A general term applied to all plants which grow in water, both in and outdoors. Perhaps the most familiar of all are Nuphars and Nymphaeas. With these the following, amongst many others, may be associated, but some require a greater depth of water than others: Acorus Calamus, Alisma Plantago, Aponogeton distachyon, Butomus umbellatus, Calla palustris, Hottonia palustris, Limmanthemum nymphaeides, Pontederia cordata, Sagittarias, Stratiotes aloides, Trapa natans, Typha angustifolia and T. latifolia, and Vallisneria spiralis (indoors).
