The scalding water harms the foliage, not the roots, which is why it's best for small weeds. ... "Boiling water can scald foliage or kill any plants it comes into contact with," says Vater ...
Scalding is a form of thermal burn resulting from heated fluids such as boiling water or steam. Most scalds are considered first- or second-degree burns, but third-degree burns can result, especially with prolonged contact.
Leaf scorch (also called leaf burn, leaf wilt, and sun scorch) is a browning of plant tissues, including leaf margins and tips, and yellowing or darkening of veins which may lead to eventual wilting and abscission of the leaf. [1]

The plants may recover during the night when evaporation is reduced as the stomata closes. [2] In woody plants, reduced water availability leads to cavitation of the xylem.

Surface and ground water stagnation; Trapped water stagnation. The water may be trapped in human artifacts (discarded cans, plant pots, tires, dug-outs, roofs, etc.), as well as in natural containers, such as hollow tree trunks, leaf sheaths, etc. To avoid ground and surface water stagnation, the drainage of surface and subsoil is advised.
General phytotoxic effects include altered plant metabolism, growth inhibition, or plant death. [2] Changes to plant metabolism and growth are the result of disrupted physiological functioning, including inhibition of photosynthesis , water and nutrient uptake, cell division , or seed germination .
