It is better to water the plants in the morning. Firstly, plants need water during the days for growth process. The leaves have time to dry water drops on them. if you water in the evening, the leaves are wet for the whole night that can increase the cause of fungal diseases. Therefore, it is better to water in the morning if possible.

thanks 🙏. I usually water the plants in the evening. Now I know.

Mojam Sometime, you have no choice if you are busy in the morning. Please take care not to wet the leaves if you are watering the plants in the evening.
