When to Divide Plant Bulbs
How often should I divide bulbs? That really depends on the flower. As a rule, however, bulbs should be divided when they get so overcrowded that it’s noticeable. As bulbs grow, they’ll put out little offshoot bulbs that cluster around them. As these offshoots get bigger, the space the bulbs have to grow starts to get too crowded, and the flowers stop blooming as vigorously. If a patch of flowering bulbs is still producing leaves but the flowers have gotten lackluster this year, that means it’s time to divide. This is likely to happen every three to five years.
How to Divide Flower Bulbs
When dividing bulb plants, it’s important to wait until the foliage dies back naturally, usually in the autumn. The bulbs need that foliage to store up energy for next year’s growth. Once the leaves have died, carefully dig up the bulbs with a shovel. Each larger parent bulb should have several smaller child bulbs growing off it. Gently pry off these child bulbs with your fingers. Squeeze the parent bulb — if it’s not squishy, it’s probably still healthy and can be replanted. Replant your parent bulbs where they were and relocate your child bulbs to a new spot. You can also store your new bulbs in a dark, cool, airy place until you’re ready to plant them again.
