seed In botany, a seed is a plant structure containing an embryo and stored nutrients in a protective coat called a ''testa''. More generally, the term "seed" means anything that can be Sowing, sown, which may include seed and husk or tuber. Seeds ...

; cover the seed thinly with fine soil, and press the surface firm. When the seedlings are large enough to handle, prick them out in pans or pots of similar soil, and when more advanced pot them singly in 10 cm pots, using soil a trifle less sandy. They should be grown in shallow frames facing the north. If so situated that the sun shines upon the plants in the middle of the day, they must be slightly shaded; give plenty of air, and never allow them to get dry. When well established with roots, shift them into 15 cm pots, which should be liberally supplied with manure water as they get filled with roots. In winter remove to a pit or house, where a little heat can be supplied whenever there is a risk of their getting frozen. They should stand on a moist bottom, but must not be subjected to cold draughts. When the flowering stems appear, give manure water at every alternate watering. Seeds sown in early spring, and grown on in this way, will be in flower by Christmas if kept in a temperature of from 5° to 7 °C at night, with a little more warmth in the day. Those sown in April and May will follow them during the early spring months, the latter set of plants being subjected to a temperature of 4° to 5 °C during the night. If grown much warmer than this, the chrysanthemum leaf miner may damage the leaves, tunnelling its way between the upper and lower surfaces and making whitish irregular markings all over. Such affected leaves must be picked off and burned.
