April.
Most of the hardy annuals may still be sown this month. Those sown in March will be coming up, and you must remember what we told you about the importance of thinning out. In some gardens nearly all annuals are raised in boxes, and pricked out in the borders where they are to bloom. We tell you this because you may belong to a garden where you can get all the annuals you need given this month in the shape of little ready-made seedlings. You must plant them several inches apart on a showery day, and shade them from the sun at first; a tent made of four sticks and a newspaper will serve when there is no wind. As soon as they have taken root, and look well established, it is a good plan to pinch off their tips with your thumb and finger, because then they will make spreading side shoots, and give you more flowers. You can pinch most of your annual and herbaceous plants in this way when they are young, but you must not do it to any plant growing from a bulb or a corm, such as a Lily or a Gladiolus. Some tuberous plants, such as Dahlias, may be pinched with advantage.
Roses are pruned in March or April, but the different varieties need different treatment. You must get some good advice about your special kinds, or be content to cut away the dead-looking wood. The green fly begins this month, and you should keep your Roses free from it, either with an aphis brush or by spraying with quassia chips and water as recommended on p. 126.
Weed hard this month, as you do not want any weeds to seed themselves, and they will do so if you neglect them.
