What to do when roses keep attracting pests? 3 tricks to free you from the medicine cabinet

Among all flowers, the one that attracts pests the most is probably the rose. Roses bloom for a long time and have a strong fragrance, so at this time it is unavoidable that small flying insects will appear or disease problems will arise. Today, Huahua is here to give everyone a few tips for dealing with the common disease problems of roses, so they can shake off the title of "medicine cabinet" from now on!

1. Black rot

Black rot is a common disease of roses, and many roses end up "breathing their last" because of it. The sign of black rot is that small dark brown spots first appear on the leaves. Slowly these spots grow larger and larger until they spread over the entire rose plant, and finally the rose begins to drop its leaves.

We can prevent rose black rot in advance. In spring and summer, it is best to spray zineb once every half month, which can reduce the chance of black rot appearing. If it has already appeared, do not panic. First remove all the leaves that have black rot, then spray with a disinfecting solution such as carbendazim. After continuing this for about a week, there is basically no problem left.

2. Powdery mildew

Powdery mildew is also a relatively common disease of roses. The signs of powdery mildew are similar to black rot: the leaves are covered with white powder, and in severe cases the entire leaf is plastered over. How could a rose lacking photosynthesis possibly grow vigorously like that?

When powdery mildew first appears on the leaves, it generally gathers on the edges and the underside, then slowly spreads to the entire leaf, and sometimes even the petals may be affected. Powdery mildew generally appears more often in spring and autumn. When it appears, we can spray it with the same disinfecting solvent used to treat black rot, but because powdery mildew sticks to the leaves, you can add some dish soap or other viscous liquid to the solution to help remove it.

3. Thrips

Thrips are extremely harmful to roses. As soon as they appear, the leaves of the rose slowly shrivel and become deformed, and after a long time the growth rate of the rose is also affected. Thrips mostly begin to reproduce in spring, and by summer and autumn they run rampant on roses.

In spring, we can spray some imidacloprid in the evening once every half month to prevent them. If in summer and autumn the leaves still show twisting and shriveling, then it is necessary to spray imidacloprid over a long period to wipe them out.

Roses are beautiful, but you still need to patiently help them get rid of diseases so they can bring their fragrance to everyone. If you have better pest-repelling methods, leave a comment and share them with Huahua!
