What to do if dahlia leaves turn yellow

1. Replace the potting soil:

Reason: Inappropriate potting soil can easily cause its leaves to turn yellow. Dahlias are suitable for growing in loose and well-drained soil. If heavy clay soil is used, it will not only cause the leaves to turn yellow, but also be detrimental to its growth.

Solution: You can replace it with suitable soil, which will not only help improve the yellow leaves, but also be of great benefit to its growth and development.

2. Apply fertilizer appropriately:

Reason: Some people apply a lot of fertilizer to make it grow faster, which can easily lead to yellow leaves or even withering and rotting.

Solution: First, remove the yellow leaves, then water it thoroughly and place it under the sun. When applying fertilizer, be moderate and do not apply too much or too frequently.

3. Reasonable light control:

Reason: Dahlias like sunlight. If they are exposed to excessive sunlight during the growing period or do not receive enough sunlight, their leaves will turn yellow.

Solution: Place it in a sunny place without being overwhelmed by the sun. If the sunlight is very strong, move it to another place.

4. Water appropriately:

Reason: Dahlias are afraid of waterlogging and are not drought-tolerant. Excessive watering or lack of water will cause the leaves to turn yellow.

Solution: When watering it, you should wait until the soil is completely dry and then water it thoroughly. If there is water in the pot after rain, drain it out in time.
