Mulching old newspapers is bad or not?
Honestly, I am also interested in this, because I have a lot of newspapers, but I still don’t dare because I don’t know whether printing ink is harmful to plants or not. I stopped for myself on two types of mulching - I mulch the beds with straw and hay, but this year I put cardboard in the aisles from the weeds. The result of combating weeds with cardboard suited me perfectly, because weeds still crawl through the hay. I only choose cardboard without a picture.
The paper itself as a mulch, I didn’t like very much last year. It dries out after watering and doesn’t fit tightly to the ground, which makes it possible for the soil to dry under this mulch and weeds to grow well in open places.
It is better to use a newspaper as a bottom layer for tracks sand or rubble. Grass does not grow, sand is not absorbed into the soil.
And as a mulch, the newspaper must be sprinkled on top of the same grass, husk or soil.
Not harmful. In the program "Good Morning" on Channel One, they recently talked about this method of protecting plants from weeds and retaining moisture in the soil. Just do not take glossy magazines, it is better to use ordinary non-colored newspapers.
Spread the newspapers around the plants (or cut holes), pre-water the soil, and cover with straw or sawdust on top. Dry weeds will do as well.
It seems to me that mulching the soil with old newspapers, magazines, books and other waste paper can do much more harm than good to the garden. Well, what's the use of these newspapers, how much they have? Scanty. Even if the newspapers cover the soil for a while, it is only until the first little rain, which will instantly destroy the paper, turn it into powder and send it to the lower layers. But how much printing ink will be with this paper powder! See how many bold print and photos are in the newspapers! They are all black. And hands after these newspapers are black. That is, even if the paper remains on the soil for some time in a not completely destroyed state, the paint will float first. And it will nourish the roots of plants with such Mendeleev's "good" that all the benefits will come to naught.
Mulch the land with traditional and natural organic. This is dried grass, sawdust and shavings.
Colored paints are more modern and poisonous. And black and white are less toxic, now there is almost no lead.
Therefore, glossy magazines are not suitable, and newspapers are useful.
The meaning of mulch is to preserve moisture under it, create more comfortable conditions for the roots, and therefore for the plant itself. Therefore, newspapers are placed in several layers (it makes no sense - it dries up quickly and lets weeds through), sprinkling it on top with even earth or clay, sand to protect it from the wind.
It is best to use traditional mulch, such as: hay, peat, straw, sawdust of hardwood (but sawdust slightly acidifies the soil), fallen conifer needles (iglitsu, it also slightly acidifies the soil), humus, cardboard packaging. In extreme cases, you can even use roofing felt, plywood trimming and even larger stones (for mulching pristvolny circles, for example). To protect the soil from acidification, it is necessary to add dolomite flour, fluff lime or something similar in the fall before digging.
Compost can also be mulched, but it can contain weed seeds that will begin to germinate. But one of the purposes of mulch is to reduce the number of weeds.
Any organic material of natural origin can be used: straw, compost, sawdust. I would not use newspapers and, especially magazines, because printing ink contains harmful substances - in the usual black lead from the type, in colored dyes, which include toxic metals such as cadmium.
No, it's not harmful. Cut paper is perhaps one of the most common methods. I like hay more, when I mow the lawn with a trimmer, then I pick the grass with a rake and sprinkle it under the bushes, and fertilizes the soil (in the process of decay) and watering is convenient, water normally leaves the ground. In Turkey, I somehow saw beds covered with black polyethylene in fields with vegetables, then I read that our gardeners do this too (cover the beds with foil, make crosswise cuts and then plant seedlings in the holes (there are no weeds, water is kept in the ground, fruit clean) - but I do not have drip irrigation, so pull the film back and forth, what will become of it in the season - that's how I get along with hay.
Black and white newspapers are used for mulching the soil, it is believed that printers currently use lead-free paint and such paint is not hazardous to health. Colored newspapers should not be used for mulching, as colored paint contains toxic substances. Black and white newspapers should be used alternating with straw, grass cuttings, sawdust, eggshells, tops and plant debris to speed up the decomposition of the paper. It is good to mulch with straw, grass, compost, but pine needles and dry oak leaves are not suitable for mulching, since they have a long rotting process, and pests hibernate under dry leaves.
