Black Spots on Roses – How to Treat them?
Black spots on roses
commonly occur due to infestations. Rose plants are those that add color and beauty to your yard, but if these beautiful plants get infested then the entire garden looks dull. So, here are some of the methods to treat and prevent
black spots on roses.
Treatment and Prevention of Black Spots
There are many natural ways to control these black spots. You need to monitor your plants regularly to watch out for the signs of infestation and take action immediately before the entire plant gets destroyed. So, here is how you need to manage black spots on plants:
Plant Roses in Full sun
When you plant keep your roses in a place where they get six to eight hours of sun light every day, then you would not only have roses that grow more robustly, but also rose plants that have more resistance to these black spots. These dangerous spots love moisture and in shade, make water evaporation very slow. When your rose plants get enough sun light, the evaporation takes place quickly. This not only helps to prevent black spots but also the other fungal infections.
Plant Roses in a Site that has Proper Circulation
The logic is the same because with plenty of air circulation, the newly germinated black spores are eliminated from the rose plants. If they are planted in an area with poor circulation, then the spores do not go anywhere and they get stuck to your plants and start damaging them.
Do not excessively water the plants as they tend to wet the foliages. It is efficient to water at the ground level as the water lost to evaporation is very less . Do not water late in the day as well because the water evaporates at a slower rate in the evenings.
Remove Leaves that are Infected
The moment you see a black spot, you must immediately remove the infected leaf, flower, or bud. Throw the infested part away. If you keep checking your plants from time to time and remove the infected foliage, then you would keep black spots under control.
Keep the Garden Clean
Pick up and throw away the fallen rose regularly. This must be done, especially during the cold winter months. Rake the area, dispose the debris, and the entire area must be given a mulch i.e. three inch deep layer. This must be done before the new foliage appears.
Select Resistant Cultivators
If you have had problems with black spots very frequently, then make sure that the new roses that you add to the garden are resistant.
These are some of the ways to treat and prevent
black spots on roses.
I hope that you have understood the ways to control these black spots and you would practice them to keep your roses healthy.
