Distances for planting annuals (or plants treated as annuals).
Only an approximate idea can be given of the distances apart at which annuals should be planted, for not only does the distance depend on the fertility of the land (the stronger the soil the greater the distance), but also on the object the person has in growing the plants, whether to produce a solid mass effect or to secure strong specimen plants with large individual bloom. If specimen plants are to be raised, the distances should be liberal.
The distances here given for some of the commoner annuals may be considered to represent average or usual spaces that single plants may occupy under ordinary conditions in flowerbeds, although it would probably be impossible to find any two gardeners or seedsmen who would agree on the details. These are suggestions rather than recommendations. It is always well to set or sow more plants than are wanted, for there is danger of loss from cut-worms and other causes. The general tendency is to let the plants stand too close together at maturity. In case of doubt, place plants described in books and catalogues as very dwarf at six inches, those as medium-sized at twelve inches, very large growers at two feet, and thin them out if they seem to demand it as they grow.
The plants in these lists are thrown into four groups (rather than all placed together with the numbers after them) in order to classify the subject in the beginner’s mind.
6 to 9 inches apart
