Hydrangeas are considered easy-care plants. However, if something is wrong with the care or the location, they usually give very clear signals. In this article you will find out how to correctly interpret the most common deficiency symptoms.
How do I recognize deficiency symptoms in hydrangeas?
There are various deficiency symptoms that hydrangeas show as soon as they lack nutrients, sun or water. But too much of one of these factors can also cause deficiency symptoms, so the signs are sometimes not so easy to interpret. It is important to eliminate the deficiency as quickly as possible so that the plants can recover quickly.
What deficiency symptoms can occur in hydrangeas?
The most common deficiency symptoms in hydrangeas include:
- yellow, brown or black leaves
- lack of flowering
- sticky leaves
- hanging flowers and leaves
- unwanted color change
If you notice one or more of these signs on your hydrangeas, you should determine the problem and correct it immediately.
What can yellow leaves on hydrangeas indicate?
Yellow leaves are caused by a so-calledChlorose, which means that the plant produces less chlorophyll. Chlorosis can be caused by various deficiencies in hydrangeas, for example iron deficiency, magnesium deficiency or nitrogen deficiency. While the former primarily affects older leaves, an iron deficiency first becomes visible on young leaves through their yellowing. You can determine the defect using a soil analysis (€22.00 on Amazon). Fertilize your hydrangeas to address the deficiency, but avoid overfertilizing.
What's wrong with my hydrangeas when the leaves turn brown?
Brown leaves on hydrangeas can indicateFrost. If the leaves have brown spots, leaf spot disease may also be the cause. Fungal infestation can be caused by moisture and a lack of sunlight.
Why are my hydrangeas hanging?
Hanging hydrangeas can be a sign ofincorrect watering. Both too much and too little water will cause the hydrangeas to hang their heads. The hydrangea also reacts to a lot of rain or strong heat with drooping shoots. They usually recover on their own, but you should protect your shrubs accordingly to prevent further damage.
Why does my hydrangea only produce a few or no flowers?
If the hydrangea flowers are not as lush as usual, this could be due to the following reasons:
- Too shady location
- Wrong cut
- Frost after shoots
- Fungal infestation
Even if you have over-fertilized your hydrangea, it may not bloom.
Tip
Identify deficiencies early
Even with conscientious care, hydrangeas can suffer from a deficiency. If you regularly check your plants for any deficiencies, you can quickly correct the deficiencies before your plant suffers long-term damage.
