How late can you plant spring bulbs? The main thing you need know about when to plant bulbs is that you can plant bulbs until the ground if frozen. Frost does not make a difference in when to plant spring bulbs. Frost mostly affects plants above the ground, not those below the ground.
What happens if you plant your bulbs too late?
If you miss planting your bulbs at the optimal time, don't wait for spring or next fall. Bulbs aren't like seeds. They won't survive out of the ground indefinitely. Even if you find an unplanted sack of tulips or daffodils in January or February, plant them and take your chances.
When should I plant spring bulbs?
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.
