We should fulfill the water requirement of the plant especially when you are growing them in pots or containers. Generally plants consists of deep roots to find moisture but when you grow plants in container it is not possible to grow the plants with deeper roots because of limited container size.
Sometimes we observe that the roots of plants comes outside through drain holes which resembles that the plant is looking for some additional water.
If you are growing plants in hot climatic conditions, you should water them regularly.
Smaller containers accommodate less water when compared to larger containers. So, water them in required proportions.
You can measure the moisture levels in the soil by using moisture gauge or by placing your finger into two inches deep in the soil. If you feel that the soil is dry, it needs watering else it does not require water.
Prefer watering the plants in the morning sessions. So that, excess water can be dried out and it aids in prevention of the formation of fungus. If you water in the evening, you should always water at base of the plants.
If your composting layer or mulching layer become too much dry, you need to water little bit more because sometimes these layers acts as resistant layers.
When your plant is in flowering or fruiting stage, it requires more water. Some plants like tomatoes will never accept uneven watering.
If you notice that your container is totally dried then place it in tub of water and let it soak for 15 mins to rehydrate.

Both over and under watering destroys your plant growth. Use moisture gauge to determine the dampness of the soil.
Provide water regularly for healthy plant growth. Provide rain water if possible because it is free from chemicals. If you use municipal water make sure that it is non chlorinated.(catch the water in bucket and leave it aside for 20-40 hours so that the chlorine present in the water will evaporate.)

When you grow plants in terracotta pots, there will be a lot of moisture escape due to its porosity. Hence, watering must be done in regular intervals.
Choose wide rimmed terracotta pot instead of less surface area pot.
Avoid using of dark colored containers because they easily heats up and dries up.
Use coconut lining when you are using plastic containers in hanging gardens because it prevents drying up of soil.
You can grow plants by placing a plastic bag with drain holes inside the plastic pot which helps in increased insulation and decreased moisture escape.
Mulching with wood chips or pebbles prevents the loss of water.
Place the container in shady areas during sunny part of the day because it helps in slowing down of moisture escape.
Water Retaining Crystal:
Water retaining crystals absorbs excess water and slowly releases it, when it is required.
