I didn't think cornmeal could still be used to weed. Do you think it's a bargain?

In a foreign language, I saw a method of weeding weeds with corn gluten meal, and I didn't think about it. Isn't that used to feed pigs?

(it can be seen that the content of nitrogen, phosphorus and potassium is 8-0-4, which is also fertilizer.)

In fact, if you go to buy corn gluten meal, most of what you buy will be feed, and it will only be effective if you buy it from a horticultural shop.

In modern horticulture, the main ingredient of herbicides in many areas is corn gluten meal. You can look at the packaging when you buy general herbicides.

In China's "Journal of Plant Protection", I also saw the "pre-bud herbicidal activity mechanism of corn gluten meal". Corn gluten meal has a particularly good control effect on 8 major weeds, but it is not like the herbicides in the past. You can use it at any time. The use of corn gluten meal has a certain time limit, and other ways of using extra heat must be used when the seed germ germinates to be effective.

In horticulture, we should use more organic methods to weed or not, and constantly develop healthy and green gardening. Previously harmful pesticides or methods should not be banned (especially those that cause permanent damage to the soil). There are also some very effective but will be questioned (pesticide harm).

The birth of some new health products is in line with the development of the times. Gardening books published ten years ago may have to be eliminated, and articles on horticulture need to be constantly updated.

Corn gluten meal is a very new product, and it was only more than 20 years ago that a professor in the United States discovered that it was very effective in preventing weeds from sprouting.

This thing is a corn by-product, used to feed pigs, but also good or bad, it is also high in nitrogen fertilizer.

In foreign gardening shops, large bags of herbicides containing corn gluten meal are sold in many places. It says 100% corn gluten meal, or sold under another name, contains about 90% corn gluten meal. Whatever the name, the keyword is "inhibit seed germination", which means to stop weed seeds from germinating.

In the packaging of these cornmeal, it is emphasized that it is most effective for dandelion and horse grass, as well as for other common weeds.

The best effect is achieved in two periods of use, because the main germination periods of these weed seeds are in two critical periods, so you can get twice the result with half the effort.

(forsythia flower)

Especially in early spring, it is the most important time for weeds to sprout. To accurately judge the time, you can refer to the time when forsythia blossoms to two weeks before the lilac blossoms. If you don't have these two kinds of flowers near your house, ask the florist because the time varies from district to district. (florists in the south can refer to Sizhao's blooming for two weeks. )

Another period is from late August to early September in autumn.

(lilac)

The grass should be wet when it is used, and it will rain within two days. If it doesn't rain, you have to water it yourself. In short, there must be water after use before cornmeal can enter the soil. But at the same time, do not have too much water, so that the effectiveness of cornmeal will be diluted.

(dandelion)

Corn gluten meal appears to replace weed control agents that have been severely attacked in the past. It is 100% natural, so it is non-toxic and harmless to humans and animals.

(the above nitrogen fertilizer is very high and has been sold as a nitrogen fertilizer.)

Its function is that when the grass seed is opened to germinate, it will make the seed dry and lose its ability to germinate. So if you've just sowed grass, don't use it. After using corn gluten meal, plant grass at least every six weeks, preferably for two months. )

(Ma Tangcao)

At present, the corn on sale is either powdered or granulated. It should be used evenly, and it is best to use grass sprinklers or fertilizers. There are instructions on the package. It is also quite nitrogen fertilizer, so do not fertilize the lawn after use.

Note: to buy corn gluten meal, you must buy it in a horticultural shop. If you buy it in a feed store, it is several times cheaper, but it is fed to pigs and does not prevent seeds from germinating. I didn't expect that cornmeal can still be used to weed. Do you think it's a bargain?

Corn gluten meal can be used for a short period of time and the amount of corn gluten meal is not small, so just take a look at it. Generally still use the common weed control agent, the effect is also much better. Many pesticides are banned because of their permanent damage to the soil, so these organic weeds and fattening things are worth studying.
