Yarrow does need to be thinned periodically to maintain its growth and prevent it from becoming unruly. Thinning out yarrow plants allows you to control where it spreads and when, ensuring that it doesn’t overcrowd other plants or areas of your garden. In addition, dividing yarrow every 3-4 years helps to rejuvenate the plant and promote healthy growth.
One important step in thinning yarrow is to cut the stems at an angle when you are pruning or deadheading the plant. This angled cut helps to prevent water buildup in the stem, which can lead to rot and disease. By cutting the stems at an angle, you create a small slope that allows water to easily drain away from the cut area. This simple technique can help to keep your yarrow plants healthy and thriving.
Another method of thinning yarrow is to dig up the plants and divide them every few years. Yarrow is a fast-growing plant that can quickly spread through its rhizomes or by self-seeding. If left unchecked, it can start to take over an area and become overcrowded. Dividing the plants allows you to control their growth and ensure that they have enough space to thrive.
To divide yarrow, start by digging up the entire plant using a garden fork or spade. Carefully lift the plant out of the ground, trying to keep the root ball intact. Once the plant is out of the ground, you can gently separate the clumps by pulling them apart or using a sharp knife or garden shears to divide the roots. Make sure that each divided clump has a healthy amount of roots and foliage.
After dividing the yarrow, you can replant the clumps in different areas of your garden or share them with friends and neighbors. Be sure to choose an appropriate location for each divided clump, taking into consideration the plant’s sunlight and soil requirements. Water the newly planted divisions thoroughly and continue to provide regular care and maintenance as needed.
Dividing yarrow every 3-4 years not only helps to control its spread but also promotes healthier growth. Over time, yarrow plants can become crowded and less productive. Dividing them allows for better air circulation and access to nutrients, resulting in stronger, more vibrant plants.
Thinning yarrow is an essential task in maintaining its growth and preventing it from becoming unruly. By cutting the stems at an angle to avoid water buildup and dividing the plants every few years, you can control the spread of yarrow and promote healthier growth. Remember to choose appropriate planting locations for the divided clumps and provide regular care and maintenance to keep your yarrow plants thriving.
