What to do if the leaves of Phlox paniculata turn yellow

=Causes and solutions

The yellowing of the leaves of the Phlox will definitely affect its appearance and growth. So what is the reason for the yellowing of the leaves?

Overwatering

Phlox likes moisture but avoids waterlogging, so excessive watering will not promote its growth, but will cause some adverse symptoms, such as yellowing leaves.

Because the philadelphus is also drought-resistant, its roots will grow normally in dry conditions, but it is afraid of being soaked in water. Once there is too much water, it will cause root rot, which will affect the growth of the leaves and gradually turn yellow.

Prevention and control measures

Reduce and control the amount of watering, especially in the cold autumn and winter. Do not water too much to prevent root rot.

Lack of light

Schefflera prefers high temperature environment and needs sufficient light to grow. Therefore, when you place Schefflera in a shaded place, it will not be able to absorb the light it needs for growth, and its leaves will wilt and turn yellow.

Prevention and control measures

Place the philadelphus in a place with sufficient light and good ventilation, and be careful to avoid direct sunlight in summer.

Pests

The most common pest of Phlox is red spider mites, which can damage the leaves and cause reddish-brown spots to appear on the leaves. When the red spider mites suck the sap of the plant, the leaves will gradually turn yellow.

Prevention and control measures

You can rinse the plants with water to wash away the red spider mites, or spray the plants with pesticides to eliminate the pests.

High fertilizer concentration

Perhaps when you were fertilizing the philadelphus, you applied fertilizer too many times and at a high concentration, which would burn the roots of the plant and cause the leaves to turn yellow.

Prevention and control measures

If this happens, stop fertilizing immediately, or dilute the concentrated fertilizer you have already applied with water. Be sure to flush it several times.
