All the hydrangeas they are shrubs of singular beauty. They bloom in such a way that the flowers cover almost the entire plant, something they do during spring and summer. But while we might think that they are very easy to care for, the reality is that this is not always the case. They have some requirements that must be met so that they can grow and develop without difficulties, to prevent problems from arising, which I am going to tell you about below.
Find out what the hydrangea problems and how to fix them.
Chlorosis
Chlorosis appears when roots cannot absorb iron or magnesium from the ground or substrate, which causes rapid yellowing of the leaves (except the veins, which become visible). It is one of the most common problems when grown in fields or pots whose soil has a high pH (greater than 6).
This is the treatment:
- Water with acidic water. If the one in your area has a lot of lime, add the liquid of half a lemon to 1l of water.
- Use substrates for acidophilic plants.
- Remove chlorotic leaves (they will not turn green again).
Fallen leaves, like limp
When that happens it can be for several reasons:
- Lack of irrigation: During spring and summer it must be watered frequently, avoiding letting the substrate dry out.
- The direct sun gives it: the leaves can get burned if they are exposed to the star king. Always put it in semi-shade.
- It's inside: unfortunately, it is not adapted to the conditions of the home. Lack of light and ventilation can cause you many problems.
Does not bloom
You buy yourself a beautiful plant full of flowers, but you can only enjoy them during that year. Why? Because it turns out that to flower again you have to fertilize it during the warm months with acidic plant fertilizer, and you also have to prune it in mid-autumn. How? So:
- Of the stems that have not flowered, you should count two buds from the top and make a beveled cut on the last one.
- From the stems that did bloom, you have to count two buds from the ground and cut off the latter.
With these tips, your hydrangea will not have problems again.
I love hydrangeas and I have two but now their leaves are yellow and they hardly flower, I don't know if it's because the earth is very bad, could you help me.
Hi Lula.
What kind of soil do you have on them? It is important that the water can filter well and quickly, so a good mixture would be black peat mixed with perlite and blonde peat in equal parts. But it is also necessary that the water is soft, without lime, since otherwise it may have iron chlorosis (lack of iron).
A greeting.
Hello, my problem is that they gave me in April 2008, a beautiful hydrangea, already with flower, they told me to prune it and I did so, the result is that it has not flowered again, you have old and new branches, but today today, only one branch has leaves. On the other hand, I bought one, very pretty pale pink and already flowered, that would be in January or February of this year, well, white spots are coming out on the leaves, help for both of us please, I have a lot for them Dear. And tell me also, to the new one, when the dry flower starts to grow, should I cut them? Thanks in advance.
Hello Lola.
How often do you water them? What substrate do you have on them? It is important to bear in mind that hydrangeas have to be watered quite often with rainwater or without lime, and you only have to wet the soil. Likewise, it is highly recommended to avoid planting them in pots without holes since their roots will rot quickly.
By the way, another thing to do is plant them in larger pots every so often, using substrate for acidic plants.
After flowering, the dried flowers must be cut; and at the end of winter / spring, more must be pruned so that new branches sprout.
