One of the keys to keeping hydrangeas blooming is proper deadheading. Deadheading is the process of removing the spent blooms from the plant. This is done by cutting off the flower head just above the first set of healthy leaves or buds. By doing this, you are not harming the plant at all, but actually encouraging more blooms to form.
When you deadhead hydrangeas, it sends a signal to the plant to stop producing seeds and instead focus its energy on root and foliage development. This redirection of energy makes the plant stronger and healthier, which in turn leads to more abundant blooms in the future.
To effectively deadhead hydrangeas, you will need a sharp pair of pruners or scissors. Look for the faded or wilted blooms and trace the stem down to the first set of healthy leaves or buds. Make a clean cut just above this point, being careful not to damage any new growth or buds nearby. If you are unsure about where to make the cut, simply follow the stem downwards until you find a healthy leaf or bud.
It’s important to note that not all hydrangeas bloom on new growth. Some varieties, such as the mophead or bigleaf hydrangea (Hydrangea macrophylla), bloom on old wood, which means the flower buds are formed during the previous growing season. These types of hydrangeas should be deadheaded immediately after flowering to allow time for new buds to form for the following year.
In addition to deadheading, there are a few other steps you can take to keep your hydrangeas blooming. Here are some tips:
1. Prune at the right time: As mentioned earlier, it’s important to know the blooming habit of your specific hydrangea variety. For those that bloom on old wood, pruning should be done immediately after flowering. For those that bloom on new wood, pruning can be done in late winter or early spring before new growth begins.
2. Provide adequate water: Hydrangeas prefer consistently moist soil, so be sure to water them regularly, especially during dry periods. However, be careful not to overwater, as this can lead to root rot. A layer of organic mulch around the base of the plant can help retain moisture.
3. Fertilize appropriately: Hydrangeas benefit from regular fertilization to promote healthy growth and blooming. Use a balanced fertilizer specifically formulated for acid-loving plants, following the instructions on the package. Avoid excessive use of high-nitrogen fertilizers, as this can result in lush foliage but fewer blooms.
4. Protect from extreme conditions: Hydrangeas can be sensitive to extreme heat, cold, and wind. If you live in an area with harsh weather conditions, consider providing some protection, such as a temporary shade cloth or windbreak, to shield the plants.
5. Monitor for pests and diseases: Keep an eye out for common hydrangea pests like aphids, spider mites, and powdery mildew. Regularly inspect the leaves and stems for any signs of infestation or disease, and take appropriate measures to control them if necessary.
By following these tips and regularly deadheading your hydrangeas, you can help ensure a continuous display of beautiful blooms throughout the growing season. Remember to pay attention to the specific needs of your hydrangea variety and adjust your care accordingly. Happy gardening!
