There are two groups of bulbs: those which should be plantedin the fall to produce flowers in the spring, such as tulips, narcissi,and crocuses, and those which should be planted in the spring to pro-duce flowers in the summer and early fall, such as gladioli. (Inbotanical science in the case of the gladiolus the term is "corm" ratherthan "bulb.")
Time for Planting Bulbs. Nothing is gained by planting spring-flowering bulbs, such as tulips, narcissi, crocuses, hyacinths, squills,and Spanish irises, before September or October. The reason forplanting, then, is that they keep better in the ground, and as they startto root in the fall they begin growth earlier in the spring. It is hardlypossible to plant bulbs of this group early enough in the spring to secureany flowers the same season. These bulbs should be planted notearlier than six weeks before the hard frosts. Narcissi may be plantedearlier, and it is preferable to plant crocuses early. Crocuses areusually planted in the lawn. An early bloom is desirable; thereforeearly September planting permits root growth in the fall and the
