Leaves start to wilt and show brownish shade along with becoming soft and droopy.

How often to water plants?

It’s a tricky question while it varies widely for different types of plants, growing medium, soil and surface temperatures, type of the soil and age of the plants in different plant species.
The general rule that applies here for all gardening or horticultural crops is directly associated with the root health and irrigation demands that 1 square meter of a plant with completely developed foliage will require 4 liters to 6 liters of water in a day while in new plants that haven’t developed foliage yet will need some 3 liters of water in a day. The rule will remain the same if you are growing more plants in 1 square meter with little or fully developed foliage. Another rule of thumb is that almost 50% of the water applied to any growing plant is wasted either in leaching down effect or as surface runoff. So, we can employ it in the general watering plant procedures that apply water only when you feel that plants are in real need. You can also check the top 2-3 inches of the garden soil by inserting some spoon or finger into the soil, it appears wet, don’t apply the next water until it dries fully.
