The Garden Under Glass

THE BEST FLOWERING PLANTS 41 The seeds are very minute, resembling powder, and should be sown as evenly as possible on the surface of a pan of sandy soil, well drained and previously watered. The seeds must not be covered with soil. A sheet of glass and a sheet of paper will give the necessary shade and closeness of atmosphere until gemination takes place. Personally I prefer to sow the seeds as early in the year as Diagram 15.—Tuberous Begonia : 1. Seeds sown in pan, covered with sheet of glass and sheet of paper. 2. Seedlings pricked off. 3. Plantiet for potting singly. 4. Dormant tuber. 5. Tuber just starting. 6. Tuber potted too deeply. 7. Not deep enough. 8. Correct depth. possible, putting the pan in a temperature of 6o° to 65°. It is probable that the seeds will come up thickly. In any case they should be pricked off into other pans or boxes as soon as they can be håndled. This is a deli-cate and tedious but necessary operation. The after-treatment of seedlings consists of potting them along as they fill their receptacles with roots and gi ving them a more open atmosphere and cooler temperature as the season advances.
