Hydrangeas are considered robust plants, they usually require little maintenance and bloom reliably every year. If the ornamental shrubs show brown flowers, then something is wrong. In this article we explain what the cause could be and how you can counteract it.
What causes brown flowers on hydrangeas?
If hydrangeas are exposed to too much sun, watered too much or too little, or experience frost, this can result in brown flowers. You should then immediately shade the location, adjust your watering behavior or protect the plant from frost.
Why do hydrangeas have brown flowers?
If you discover brown flowers on your hydrangea, this is usually due toincorrect locationorincorrect care. Frost can also cause the hydrangea flowers to turn brown.
To what extent can an incorrect location cause brown hydrangea flowers?
The most important thing for the he althy growth of hydrangeas is thecorrect location As a forest plant, hydrangeas need a shady place where they are protected from too much sun. Direct sunlight can lead to brown flowers or even sunburn, which also causes the leaves to turn brown and ultimately the entire plant dries up.
To what extent can incorrect care cause brown hydrangea flowers?
Too much or too rareWatering can also cause brown flowers on hydrangeas. Did you know that the Latin name “Hydrangea” means “water jar”? A botanist gave the hydrangea this name in the 18th century because of its visual appearance. But the name also fits well because hydrangeas require a lot of water. If they are not watered enough, they react with brown flowers and dry out quickly. But hydrangeas also do not tolerate too much water and waterlogging well; the roots begin to rot and can no longer supply the plant with nutrients. Brown flowers are the result.
Should I remove brown flowers from hydrangeas?
You shouldremove the brown flowers. This not only improves the visual appearance, but also the growth vigor of the plant. If you cut the flowers close, there is a chance that they will sprout again.
How can I prevent brown flowers on hydrangeas?
Once you have identified the cause of the brown flowers on your hydrangeas, you can quickly respond to it:
- Always plant hydrangeas in theshade of other plants, a wall or house wall. If the site conditions change after planting, for example because a neighboring plant dies or the garden is redesigned, you should prefer a new shade source to transplanting. If the location is too sunny, you can either use plants or other shading measures to ensure that the hydrangea is exposed to less sunlight. Hydrangeas are plants that are very faithful to their location and often do not cope well with a change of location.
- Adjust thePoting behavior. The soil around the hydrangeas should always be slightly moist and never dry out. Usually it is enough to water the bushes once a week. However, on very hot summer days you should check the humidity status more often. Also be sure to water the plant from below so that the leaves and flowers do not get wet.
Tip
Frost can also cause brown flowers on hydrangeas
Hydrangeas are hardy, but frost can still cause brown flowers. To optimally protect your hydrangeas from severe cold, protect them with fleece (€34.00 on Amazon), jute or mulch. You should only plant young plants outdoors after the last frost.
