You can divide your yarrow plant. Yarrow, also known as Achillea, is a perennial plant that can spread rapidly, so dividing it every 2 or 3 years is recommended. Dividing the plant helps to maintain its health and vigor, as well as control its growth.
To divide your yarrow plant, it is best to do so in the spring when new growth is just emerging. This is when the plant is actively growing and can recover quickly from division. Start by digging up the entire yarrow plant using a garden fork or shovel, being careful not to damage the roots.
Once the plant is lifted, you can divide it into smaller sections. This can be done by gently pulling apart the clumps or using a sharp knife or garden tool to cut through the root system. Aim to create sections with healthy roots and at least a few shoots or stems.
After dividing, you can replant the sections in their new locations. Make sure to prepare the soil beforehand by loosening it and adding compost or organic matter for improved drainage and fertility. Dig a hole for each section, ensuring it is large enough to accommodate the roots without bending or crowding them.
Place the divided yarrow sections into the holes, making sure they are at the same depth as they were previously. Gently backfill the soil around the roots, firming it in place. Water the newly planted divisions thoroughly to settle the soil and provide moisture for the roots to establish.
It is important to note that not all yarrow species spread as rapidly as others, so the need for division may vary. However, if you notice overcrowding or declining health of your yarrow plant, division can be beneficial.
Dividing yarrow in late summer or early fall (mid-August through September) is generally not recommended, as it can interfere with the plant’s ability to establish before winter. However, if you do choose to divide in this season, it is crucial to mulch the newly divided plants in November to protect them from frost and temperature fluctuations.
In my personal experience, dividing yarrow plants has been a relatively straightforward process. I have found that spring division works best, as the plants quickly recover and establish themselves in their new locations. Dividing every few years has helped to maintain the health and appearance of my yarrow plants, preventing them from becoming overcrowded and promoting better flowering.
Dividing yarrow plants is a beneficial practice that can help rejuvenate and control their growth. By following proper techniques and timing, you can successfully divide your yarrow and enjoy its beauty in your garden for years to come.
