Pruning Yarrow: A Guide to Beautiful Blooms and Healthy Growth
Yarrow (Achillea) is a hardy and versatile plant that can add pops of color and texture to your garden. Proper pruning can help you achieve the desired look and encourage healthy growth. Here's a breakdown of when and how to prune yarrow:
When to Prune:
* Deadheading: Deadheading yarrow involves removing spent flower heads as they fade. This encourages the plant to produce more blooms and extends its flowering season. Deadhead regularly throughout the summer.
* Early Summer (June/July): You can prune back yarrow plants to about half their height in early summer. This helps to maintain a more compact shape and encourage bushier growth.
* Late Summer/Fall (August/September): For a cleaner look and to encourage fresh growth in spring, prune yarrow back to the ground in late summer or fall.
How to Prune:
1. Use sharp, clean pruning shears. This will help to avoid damaging the plant and prevent the spread of diseases.
2. Cut back the flower stalks. When deadheading, simply snip the stems just below the faded flower heads. When pruning in early summer, cut the stems back to about half their height.
3. Remove any dead or diseased leaves. This will help to keep the plant healthy and looking its best.
4. Dispose of the pruned stems properly. Don't compost yarrow stems unless you know they are not invasive in your area.
Additional Tips:
* Wear gloves. Yarrow can cause allergic reactions in some people, so it's a good idea to wear gloves when pruning.
* Consider the variety of yarrow you are pruning. Some varieties are more compact than others, so you may need to adjust your pruning techniques accordingly.
* Be patient. Yarrow is a hardy plant, and it can take a while to recover from pruning. Don't be discouraged if it doesn't look its best immediately after pruning.
By following these tips, you can prune your yarrow effectively and enjoy its beautiful blooms throughout the season.
