Making Herb and Vegetable Containers

Watering

Plants grown in containers need frequent watering as the containers dry fast. Watering on a daily basis is necessary to provide adequate moisture for plant growth. Apply enough water to reach the bottom of the container. Allow the excess to drain out through drainage holes. Avoid wetting the leaves when watering as this will encourage development of foliar disease. Try not to allow the containers to dry out completely between watering as this will lead to flower and fruit drop. Do not over water the plants as the container will be waterlogged and the roots will lack oxygen leading to poor growth and eventually, perhaps, the plant's death.
