Explanation: 

Detailed explanation-1: -Avoid watering a plant’s leaves to minimize disease risk. If you have a sprinkler, put it on a timer for the early morning or dusk hours, so it will dry quickly. “Watering in the morning is best as it allows the water to move into the roots zone and getting the plant hydrated before the heat of the day, ” Bachman said.

Detailed explanation-2: -On a hot, dry day (or after several days with no rain or watering), transpiration causes more water to be lost than is coming in, and the water balance within the plant can get thrown off. The dehydrated collapsing cells in the leaves and stems can no longer remain erect, and the plant begins to wilt.

Detailed explanation-3: -When relative humidity levels are too high or there is a lack of air circulation, a plant cannot make water evaporate (part of the transpiration process) or draw nutrients from the soil. When this occurs for a prolonged period, a plant eventually rots.

Detailed explanation-4: -These refer to the minimal, optimal, and maximum temperature. Vegetative phase – 25 degrees Celsius and 60-70% humidity. Flowering phase – 28 degrees Celsius and 40-50% humidity.
