Roses are some of the finest flowers to plant on your site. They have an incredibly pleasant aroma, various original colors and abundant flowering. But even experienced gardeners are not immune from problems with growing flowers. Any garden crops are susceptible to the negative influence of pests, various diseases and unfavorable natural factors. However, fortunately, all these problems can be easily dealt with with simple and affordable methods.
1. Problem analysis
Black spots are a terrible disease that can affect every leaf in your plant. The spread of the disease begins gradually, and over time it can capture the entire plant, deprive it of flowering and completely ruin it. Without treatment, black spots never go away on their own. In order for the rehabilitation of a flower affected by a fungus to go smoothly, you should adhere to clear procedures that include proper pruning and processing of the entire bush, and sometimes adjacent plants. The organic method works no worse than the chemical one, but it is safer. This will require one or more small pruners, a trash bag, and a homemade fungicide.
2. Correct pruning
Treatment of the bush begins with the need to remove all faded roses, as well as affected branches and leaves. If there are too many healthy flowers, it is advisable to partially cut them too, so that they do not take extra strength, nutrients and juices from the flower that is fighting the disease. Any cuts with a pruner are made at an angle of 45 degrees. First, all dead flowers and stems under them, about 5 cm long, are removed.
After that, you should cut off the black leaves and branches with spots. Yellow leaves can also be infected and diseased, so if there are a lot of healthy leaves, they should be removed. However, it should be remembered that the leaves are the main source of food for the plant. Therefore, leaving a completely bare rose bush is also wrong.
Helpful advice: If the affected area is too large, only the most blackened leaves should be removed.
3. Safety and disinfection
All severed leaves and twigs should be immediately put into a garbage bag without dropping to the ground. It is very important to get rid of them, as the fungal disease can continue to spread even on dead leaves, thereby posing a risk to healthy plants.
After all the affected leaves have been cut off, the pruning shears must be treated with alcohol. Next, you need to remove or prune any weeds and other surrounding plants that also have fungus-infested areas. Under no circumstances should these leaves and weeds be sent to the compost heap. Fungal disease can spread to the soil.
4. Preventive action
Despite the fact that all the soil around the infected plant has already been cleaned, additional measures are required to prevent the spread of the fungus. To do this, you need to mulch the soil with straw or bark. The layer should be at least 3-4 cm. This will prevent the fungus from infecting the plant again.
5. Correct processing
A homemade organic fungicide should be used to treat a fungus-infested rose bush. To do this, the plant must be sprinkled abundantly on all sides, including the top, leaves, trunks, the bottom of the leaves and the base of the bush near the ground. To completely get rid of the disease, this procedure will need to be repeated over several weeks, as a rule, every 7 days. If it rains, then after it stops, be sure to repeat the spraying.

6. Homemade fungicide recipe
To create a home remedy for roses, you will need some vegetable or canola oil, baking soda, and 500 ml of water. For plants that are not strongly affected by the fungus, one heaped teaspoon of soda will be enough for this amount of water, but if they are significantly sick, then two or even three should be taken. Oil only needs one teaspoon. Mix everything thoroughly.

7. Pleasant recovery
After treatment and treatment, the rose bush should look healthier and more beautiful. New, healthy shoots usually begin to form within a few weeks. Particular attention should be paid to the daily morning watering of the plant. This should be done closer to the root system, without affecting the leaves, since their constant moisture can lead to the re-spread of the fungus.
