Get the Timing Right. Spring-blooming bulbs, such as tulips and daffodils should be planted in September or October, when the soil temperatures have cooled. Summer-blooming beauties such as dahlia and gladiolus are best planted in the spring, after all danger of frost has passed.Do plants that grow from bulbs make seeds?
Although you can grow tulips from either bulbs or seeds, bulbs produce flowering plants faster. A tulip bulb produces a plant that will usually bloom the following year. Tulip seeds take only a few months to germinate, but it can be several years before the plant bears flowers.Can I plant bulbs for the summer?
Most summer-blooming bulbs need to be planted in warm, well-draining soil. If you want to give your bulbs a head start, you can pot them indoors around a month or two before your outdoor weather meets their growing conditions. Then, bring them outside to continue growing in the pot, or transplant them into your garden.Can I still plant tulip bulbs?
If your soil is workable and unfrozen, you can still plant the bulbs, but do so as early in January as possible. Note the width of the tulip bulb. Make the hole three to four times as deep as the bulb is wide. For example, if the bulb is 2 inches wide, plant it 6 to 8 inches below the soil surface.
