Weeds and Seedlings
It is most important to know what the baby-plants will look like when they come up, because one has to weed hard in the warm showery weather, and if one is not careful, mignonette, sweet-peas, and poppies may go on the rubbish heap, and chickweed and purseley be left on the flower-bed; which, although it is what the birds like, will, later, be very disheartening to you. Of course, if your seeds are well marked, there will be less difficulty, but even then weeds will come up amongst them. The only safe way is to get to know the appearance of all the seedlings, and to help you to remember it is a good thing to make little drawings of them in your garden note-book.
Autumn Sowing
Some seeds, such as cornflowers, godetias, and poppies, can be sown in the autumn. They will stand the winter as a rule and will make finer plants and blossom earlier than if sown in spring. They should be sown thinly in open ground.
Any good catalogue will give you a list of annuals suitable for your purposes and with a little advice from an older gardener you will have no difficulty in selecting wisely.
Biennials
These are best sown in May. If the garden is full they may be sown in an ordinary wooden box filled with several inches of good earth. Transplant them to their permanent places later on.
Remember that all plants will flower for a much longer time if the flowers are kept cut and any faded ones taken off.
Saving Seed
The best seed is saved from plants set apart for that purpose; for good seed comes from the first and finest flowers and not from those left over at the end of the flowering season. These plants should be sown in a little patch by themselves, should be allowed to run to seed, and carefully tended until the seed-pods are ripe enough to be gathered. If, therefore, you have not a large garden, it is best to buy most of your seed each year, using a little of your own, from which, however, you must not always expect the finest flowers. If you have no wish to keep any of your flowers merely for seeding purposes but still want, while getting flowers from them, also to save a few seeds, the thing to do is to mark one or two of the finest blossoms with a tiny piece of wool or silk (it is better when it is the color of the flower) and let it go to seed. Take special care of the plant, and cut off all other flowers as you wish to gather them. Watch the seed-pods when they are formed, and when they are ripe—that is, brown and dry—cut them off, break them open, and spread the seeds out. Look them over very carefully to see that there are no maggots amongst them, and if they are at all damp leave them in a warm place until they are dry. Then make them up in little packets, clearly labeled with their names, colors, and the date, and put them away in a dry place until next spring. In saving sunflower seeds choose your best sunflower, and when the petals have fallen tie it up in muslin, or else the birds will steal a march on you. In gathering sweet-pea pods one has to be rather clever, because when they are quite ripe they burst open and the seeds fly out suddenly, sometimes just as one is going to cut them. In one poppy pod there are hundreds of seeds, enough to stock a garden, and the same is the case with the pretty pods of love-in-a-mist. Nasturtium seeds should be picked up when they fall on the ground, and spread out until quite brown and dry. Cornflowers, which have little seeds like shaving-brushes, generally sow themselves, and marigolds do too, but they are both easy to save. In choosing a place in which to keep seeds through the winter remember that damp is not the only danger. Mice enjoy them thoroughly.
