hydrangeas burnt flowers

Having hydrangeas is something common in many houses since it is one of the most used plants in gardens and interiors and typical of Spain. However, you can often come across hydrangeas with burnt flowers. And that's not pretty.

But do you know why it happens? What are the reasons why you can find them like this and how to solve it? Next we are going to give you the keys to understand what could be happening and why your hydrangea ends up with flowers like this. And, be careful, because it can also affect the leaves.

Reasons for hydrangeas with burnt flowers

As you know, hydrangeas in general are not overly difficult plants to care for. But they do have some peculiarities to take into account that can make your plant better or worse. And these are the ones that can cause you to have problems with them, such as the fact that burnt flowers appear.

What are the reasons? We tell you.

Excessive lighting

In case you don't know, hydrangeas are plants that do not like the sun. At least not direct sun. Now, that does not mean that, if you have a hydrangea that has been around for many years, you cannot have it in the garden with hours of sun (it all depends on the adaptation of the plant).

En general, hydrangeas are shade or semi-shade. They love light, but they can't stand direct sun, not even for a few minutes or hours. Much less if it is in the middle of summer and in the hours of greatest incidence.

When the sun affects them, one of the consequences it has is the fact that burns appear. These occur mainly on the leaves and flowers and spoil the entire appearance of the plant.

The solution is simple you would just have to move it around. In this way, it would not give it the sun but it would give it the necessary light to develop properly.

Another reason for your hydrangeas with burnt flowers can be water. No, we do not mean that you water it more, which may be, but that the drops, either from irrigation water or from morning dew, can create a magnifying glass or mirror effect with the sun and cause burns on the flowers and leaves.

If that happens then you will have to, first, water only at night, rather than first thing in the morning; and second, be attentive to the dew to shake it a bit so that the drops fall. Another option is to move it to another place where it has full shade, although depending on the hydrangea it will require more or less light.

Beware of mushrooms

Sometimes the burning of flowers and leaves in hydrangeas can come as a consequence of a fungus on the plant. This can be distinguished as small white spots that are located on the leaves (both on the face and on the underside). It affects especially in spring and summer, but the truth is that it depends on the weather. If it is temperate-warm, it could affect you throughout the year.

Regarding treatment, the best thing to do is use some fungicide to treat. Another option may be to clean each of the leaves and flowers one by one with a damp cloth with alcohol or similar. It's a lot of work, especially if your hydrangea is big, but you can kill those fungi that way.

If you see that they are also on the ground, a change of substrate can help it, but be careful, because if the hydrangea is weak, the transplant can stress it and, with it, cause it to get much sicker.

excess nutrients

Imagine that you have just transplanted your hydrangea. And in addition to having put a new substrate, you decide to pay it. That supposes a nutrient overexposure. That is to say, it is as if you had paid too much and that causes burning of the leaves and flowers of the hydrangeas.

Not only can it happen for that reason, but it It can also be given by going over with the dose of fertilizer you use, for paying too much in time, or for doing it too often.

The solution is to stop the subscriber. We know that it is necessary for plants to be healthy. But all in good measure. Not by paying more you will have more flowers and a greater growth of the hydrangea.

When it is young and you have just bought it, it is best that you pay little, less than the manufacturer's dose, until it gets used to its new home. When you see that she begins to grow on her own, you will know that she is already adapted and that is when you can start fertilizing always less.

Excess of water

Finally, excess water can also be detrimental to hydrangeas, and one of the reasons for burnt flowers. When overwatered, the plant suffers. The problem is that many relate the fact that the plant looks limp to the fact that it needs more water, and they end up drowning it when in reality they do not need that.

In this case, when you go too far with water it can cause a proliferation of fungi, and that negatively affects both the root ball and the plant itself.

If you catch it in time you can save it by doing an emergency transplant (remove all the soaked soil and put dry substrate to try to stop excessive humidity). Of course, it can suffer a lot and you can't make it, but at least you will have tried.

Indeed, hydrangeas are not difficult to care for. There are those who have the best hand and who have a hard time. But they are plants that almost take care of themselves as long as you meet their needs, especially in terms of irrigation and lighting. If these two factors are well done, the plant will eventually develop properly. But when the hydrangeas have burnt flowers, it is a warning that something is not right. And it is not enough to cut those flowers and hope that everything is solved, since you have to know the reason. Shall we help you with your particular case?
