What are the disadvantages and advantages of imperial soil? Read this article to understand

Planting down mountain grass: it can make the roots healthy and the seedlings strong, because its air permeability and water retention are especially good. Planting weak grass and diseased grass: it has the ability to rejuvenate and control them. A flower friend of mine has several seedlings of diseased grass, and before, no matter what soil was used, they would not grow well. After using imperial soil, this year they sent out three strong seedlings. So imperial soil is very good for planting diseased grass and weak grass. Planting marginal grass: it can make the line art distinct. Several major disadvantages! Planting striped grass: it is easy for the art to fade, and several seedlings of golden-thread horsetail I planted all began to revert. Planting mature grass: because imperial soil favors only nitrogen fertilizer, the seedlings sent out by several mature grass plants I planted were not impressive. But there is a solution, which is to add 30% decomposed dry cow dung to the imperial soil.
