Spring and fall are the perfect seasons for dividing plants, each offering unique benefits that can lead to successful relocation and propagation.
Spring Dividing:
Dividing plants in spring allows them to adjust and recover in cooler conditions and moist soil, resulting in successful relocation. This time of year offers benefits like rejuvenating clumps, getting more plants for free, and ensuring successful division.
Fall Dividing:
Dividing plants in fall, ideal after their blooming season, can double your plants for free. However, it's crucial to wait until the plant's flowering is over to ensure a successful division. Lifting and dividing plants in mild and dry weather in early fall allows for proper establishment before winter frost. This timing benefits from the remaining warmth and moisture in the soil. Knowing when to divide specific plants like irises, hydrangeas, and delphiniums is crucial for successful plant propagation. Some plants, like delphiniums, benefit from being divided every 3-5 years in spring, ensuring healthy growth and blooming.
