Many mixtures for growing bulbs are recommended. The one we like best for bowls without drainage is gravel mixed with a little carbon. You buy it in little sacks mixed ready for use at any of the big London shops that have a gardening department, and probably at any good florist’s elsewhere. Moss-fibre is satisfactory, too, but the gravel is cleaner to handle, and the carbon keeps the water sweet. From the moment that bulbs are planted in bowls they must not be allowed to become quite dry. If you think there is too much water, however, you must put your hand over the top of the bowl to keep your bulbs in place, tilt it a little, and drain off the water. For ordinary flower-pots a mixture of leaf-mould and sand is good, and while these are in the dark you must not water much, or the soil will get sour and unhealthy. In planting bulbs for a room garden, do not set them deeply in the gravel or moss-fibre. The point of the bulb should just show above ground. This applies also to bulbs grown in ordinary pots. Whatever medium you use should be damp when you finish your planting. Your bulbs must then be put into a dark, cool place for four weeks to make their roots. An airy cellar is good, but many people use a cool cupboard. They usually choose one that is sometimes opened, and therefore aired for a moment. At the end of the four weeks the bulbs must be brought into a light and cool, but not cold, place, and it was at this stage that we found a bathroom window so useful. When the green is well up and the flowers beginning to show, they may be moved to a light place in your warm sitting-room.
