For spring flowering the seeds are sown in mid spring in well-drained pots or pans, in soil of three parts loam to two parts leaf mould, with one-sixth sand; cover the seed thinly with fine soil, and press the surface firm.

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.

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.
