Do you have roses with ruined leaves in your garden? It could be common problems, but not for this to be underestimated. Macchiate, crumpled or discarded leaves often hide precise causes. Let’s see together what to observe and how to act.
Taking leaves, which are enriched or stained in an unusual way: when roses are grown, they are signs that should raise the antennas. Often we tend to believe that it is only the heat or a little water stress, but it is not always the case. Sometimes the leaves tell a different story, made of small imbalances that develop in the ground or unwanted guests that are settled among the petals. The beauty, however, is that every problem has its own clear and recognizable signal, just knowing how to read it.
Sometimes it is a simple irrigation error, others of a disease that insinuates itself slowly. The roses, however strong, are also sensitive to environmental changes. Note a change in the leaves can be the first opportunity to intervene in the right way. Curious to understand what happens to your roses? Here is a practical guide to identify the causes and remedy it.
Roses with ruined leaves: the most insidious fungal diseases
One of the most popular problems is linked to fungal diseases that affect leaves, branches and sometimes even buds. They are easy to recognize if the details are observed well. The ticchiolature causes dark spots, almost black, bordered with yellow. Over time, the leaf falls. Rust can be seen for the appearance of small orange points in the lower part of the leaves. With the advance, the leaves deform and fall. The Oidio (or white sore) is presented with a whitish and pharynous patina that covers the young leaves, making them crop.
These pathologies are manifested above all when humidity is high and the air not very circulating. An too many evening watering can be enough or a missed pruning to favor its onset. To prevent them, it is better to avoid stagnation of water, always guarantee good ventilation between the branches and intervene with antifungal products, preferably natural. Garlic infusions, horsetail decoctions or baking soda preparations can be good allies.
Invisible but very active parasites: aphids and mites
Diseases are not the only pitfall. Parasites also do their part in compromising the health of roses. Sometimes they do not see immediately, but leave very precise signs: curled, discolored or sticky leaves, stunted growth, deformed buds. And if you observe well, you can see small insects intent on sucking the sap.
Here are the main enemies to keep an eye on:
- Aphids: they nest in young sprouts and suck their sap. Let yourself be acting undisturbed, brake the growth and make the leaves crumped.
- Red spider: prefers hot and dry climates. The affected leaves yellow, they dry out and fall.
- Cochineal: it looks like a small white or brown outcrop. It damages leaves and branches sucking lymph and weakening the plant.
The solution? Regular control is recommended, especially in the hot season. If the infestation is light, natural remedies such as Neem oil or Marseille soap diluted in water can be enough. Alternatively, there are targeted insecticides, preferably vegetable.
How to prevent damage and strengthen the ruined leaves of the roses
To prevent the roses leaves from ruining, it is better to act with method and constancy. Some tricks can make a difference. Powing regularly to eliminate old parts and promoting ventilation is a good starting point. Morning irrigation, avoiding wetting leaves, also helps prevent problems.
A well -fed plant is more resistant: using mature compost or specific fertilizers can really change the fate of flowering. Attention also to the excess of nitrogen, which makes the roses more attractive to parasites.
It is often believed that treating roses requires time and effort, but with few good habits you can avoid the most common problems. When the leaves begin to show signs of suffering, the best thing is to observe carefully: nature always sends signs, just know how to interpret them. And if you intervene in time, the roses return to bloom with all their elegance.
