If rose leaves start to change color in summer, this indicates a problem.
This is often due to a deficiency of essential microelements (iron, magnesium or manganese) or macroelements (potassium and nitrogen). In this case, the leaves turn yellow completely, in spots or only the edge of the leaf changes color. In this case, it is necessary to replenish the necessary elements.
Poor lighting also has a negative impact on the condition of roses.
As a result, the lower leaves turn yellow first, and the stems become thinner, the flowers become smaller. It is for this reason that gardeners recommend planting a rose garden in sunny areas, but at the same time, you also need to carefully monitor that there is no thickening.
Incorrect watering (drying out the soil or over-watering it) also leads to the problem.
Periodically, plants in the garden need to be checked for diseases and pests.
In such cases, roses also wither and fall off. But who exactly is the main pest of roses? Gardeners say that first of all, we are talking about aphids, spider mites, rose leafhoppers.
If the flowers were damaged by insects, then immediate action should be taken. Tobacco grass will help here, as well as special preparations, for example, "Aktellik", etc.
