Plant division during autumn is a perfect opportunity to revitalize hardy geraniums and obtain fresh plants at no cost. Learn the effortless 3-step method to rejuvenate these plants.
Hardy plants like geraniums are a favorite among garden enthusiasts, known for their long-lasting beauty and hardiness. To keep these plants thriving, it's recommended to divide them every 3-5 years. This process can be carried out in both the fall and spring, providing opportunities for revitalizing older plants and obtaining new ones for your garden.
When dividing hardy geraniums, it's essential to use clean and sharp tools. A long-handled trowel with a pointed head, a sharp shovel, garden knife, or hori hori knife are all suitable options. A multi-purpose tool with a serrated edge for cutting, a straight one for digging, an indentation for transplanting, and a tip for removing weeds can also be beneficial.
To divide the hardy geraniums, carefully dig around the plant, taking care not to damage the roots. Once the rootball is exposed, use your tool of choice to slice through it, creating several divisions. Each division should contain a healthy portion of roots and leaves.
After dividing the hardy geraniums, it's crucial to store them properly if immediate planting is not possible. All the parts should be kept together and watered thoroughly. Alternatively, the roots can be wrapped in a wet towel to prevent them from drying out.
If you're unsure about the process or have concerns about your plants, the Plantum app can be a valuable resource. This app helps identify plants and plant diseases and provides care recommendations. Nastya Vasylchyshyna, a resident botany expert at Plantum, specializes in plant morphology, phytopathology, and plant physiology, ensuring accurate and reliable information.
When it comes to planting the divisions, it's beneficial to add a handful of organic bone meal to the soil. This slow-release, phosphorus-rich substance promotes strong root development. Hardy geraniums can be planted in the fall, allowing them to bed down roots before winter, or in the spring, which ensures blooms in their first year and requires less watering to establish new clumps.
Remember, not all plants respond well to being divided. To avoid losing plants forever, it's advisable to check a guide on plants you should never divide.
Dividing hardy geraniums, along with many other perennials and shrubs, can help revitalize older plants and provide a bounty of new ones for your garden. Happy gardening!
