What is leaching in plants

The best treatment is to simply make a habit of leaching 2 or 3 times a year. If your tap water is very hard, with a pH of 7. If the plant spends the summer outside in a climate where rain is frequent, it will take care of leaching during that season.

Some plants are less tolerant of accumulated mineral salts than others corn plants, spider plants, azaleas, etc. To leach a plant, simply remove its saucer and place it in the sink, the bathtub or outdoors. Water it normally, moistening the root ball as usual.

Then wait 5 minutes this will give the salts in the soil time to dissolve , then water again, as abundantly as the first time. Excess water, now rich in salts, will flow from the pot through its drainage holes and disappear down the drain or into the ground. This will lower the concentration of salts in the pot, giving your plant a new lease on life!

One of the unsung chemical actions of water is the process of leaching. Although its name might bring about thoughts of leeches and other creepy-crawlies, it is something very different. So, what is leaching? Image 1. Water leaching through the Critical Zone.

Rain falls on a cross section of a tree atop a soil profile. Rain falls on vegetation, pools on the ground, and leaches into and down through the soil profile. Leaching is not to be confused with the use of leeches as medicine. Currently, leaching primarily describes the process of water carrying soluble substances or small particles through soil or rock.

Although this process seems trivial, leaching is one of the key processes of the Critical Zone, controlling the rate and direction in which compounds move. Leaching is actually two important actions occurring simultaneously: 1 chemical interactions with surfaces and 2 physical movement of water. As the water passes through the rock and soil, it interacts with the surfaces of the materials.

Compounds on the surface of minerals can be become dissolved. In addition, the physical movement of water can dislodge and move particles. Leaching can transport chemical compounds like dissolved substances or larger materials such as decomposing plant materials, fine rock fragments, and microbes throughout the Critical Zone.
