Schmidt, Assistant Extension Horticulturist says how the temperature of water can also affect the growth of the plant. When water that is too hot is added to a plant, the plant dies. For example, the same water used to cook carrots in the kitchen will also cook carrots in the garden. So if a person wants to kill and control weeds and unwanted plants, using hot water would be very effective, but not when trying to grow them. Some plants are more tolerant of hot water than others. Before you try to heat your plants, you should get a probe thermometer to make sure you know the water temperature that you are dumping on your plants. As long as you do not overheat your plant roots and leaves, watering with hot water will have no harmful effect. When you are heat treating plants this is an age-old way of dealing with soil-borne pests, including aphids, scale, mealybugs, and mites. When you are dealing with hot water, the magic temperature for seed disinfection would be about 120 degrees Fahrenheit
