Yellow leaves on hydrangeas? This problem, very common in the hottest months, is often the first sign that something is wrong. Find out what is missing and how to intervene is essential to bring splendor to your plants.
It happens, sooner or later, to see those leaves that are pale, tending to yellow, and a little worries about it. Ortensias are generous plants, but they also know how to be demanding. When something does not come back, they show it without many turns of words. So what to do, cut everything? Wait for them to pass? None of this. You have to listen. Ortensie are loved for their spectacular flowers and lush foliage, but sometimes they also show signs of suffering. A plant with leaves that yellow can seem sad and neglected, but behind this change a precise message is hidden. What if it were just a question of pH of the ground or some missing nutrient? In a few steps, you can understand what is wrong and return health to the plant. Also because, often, there is a tendency to underestimate small clues that instead speak clearly.
Before thinking about miraculous or drastic fertilizers, it is enough to observe the plant well: it is interesting to note that the signals are often evident, only that they are not always read in the right way. You need a little attention and some small experts from expert gardener. A more glance every now and then can really make a difference.
Why do the leaves of the hydrangeas yelling?
Don’t panic. Often it is nutritional deficienciesand with a few tricks it is remedied. Yellow, especially if it remains only on the sheets while the ribs remain green, immediately makes you think about Chlorosis Ferrica. Yes, precisely that annoying iron deficiency that hydrangeas detest. These plants, in fact, have a weakness for the land slightly acidicaround a pH of 5.5-6.5. When the ground is too calcareous, the iron is there but it is not possible to absorb.
But that’s not all. Also thenitrogen He has his part: if the yellow leaves are the oldest, he is likely to miss him, the basic element for healthy and green growth. And then there is water. How much do you need it? Not too much, not little. A straw soil can suffocate the roots, while one too dry leaves them thirsty. Result? Driven, discolored leaves, and a plant in trouble.
How to intervene effectively
Sophisticated tools or laboratory analysis are not needed here. Better to start from what you see, touch, you understand. Plants speak, even without a voice. Sometimes it is enough to observe the position of the leaves, the color of the soil, a strange inclination of the stem.
Some useful questions to ask:
- Is the ground well drained or is it always wet?
- Does the plant receive direct light for many hours?
- Are there parasites under the leaves or mold signs?
- Was a generic fertilizer or a specific acidophilic fertilizer?
And now? Here are some driver practiced:
- Correct the pH of the ground With acid peat or specific products if it is too basic.
- Administer iron cherry: It works almost immediately, and the plant thanks.
- Use nitrogen -rich fertilizersespecially when the plant is growing.
- Review the watering: better deep and distanced from frequent and light.
- Watch out for parasites: aphids and mites are tiny but very harmful.
Sane hydrangea all year round: prevention and practical advice
Keeping a healthy is not difficult, but requires a minimum of constancy. You don’t need to go crazy with a thousand products: some well targeted attention is enough. A simple idea? PACCHEAR THE GROUND with dry leaves or bark. It holds the humidity, isolates the roots and also gives a nice glance.
And then, be careful with the fertilizers. Too much zeal can return against. Better a few but good, specific for hydrangeas, perhaps gradually release.
The light also does its part. Ortensie love light, but not the ruthless one of the midday sun. An area semi shadedperhaps sheltered from a hedge or a wall, is ideal.
Treating hydrangeas is like having a chat with an old friend. Every leaf, every change, every nuance tells something.
And when you stop to really observe, the answers come on their own. Just listen.
