Speaking of coal slag, I wonder how many小伙伴们 know about it. Perhaps the post-00s generation has rarely seen it, but as an 80s, I still have a fondness for coal slag.
I remember that when I was a child, a coal stove would be lit in winter, and I even made coal balls myself. What I'm talking about today is not the coal balls, but the coal slag left behind after the coal balls are burned.
I used to live in the countryside, and I still live there now. I'm a genuine countryside girl.
In the past, we used coal slag to pave the roads, but if I see coal slag now, I wouldn't waste it like that anymore.
For those who grow flowers, coal slag is a real treasure.
My family has over 200 potted plants. If I had to buy soil for all of them, it would be a considerable expense. So, my mother-in-law collected a lot of coal slag from breakfast shops for me, which saved me a lot of money on buying soil.
Coal slag has many porous structures and is very breathable!
Therefore, coal slag can replace granular materials like ceramsite or perlite to increase the breathability of potting soil.
However, coal slag should be processed before use to reduce its fiery nature, which is more conducive to plant growth.
Methods for processing coal slag
1. Soak in water to reduce fire
Newly burned coal slag should be soaked in water to reduce its fire. Soak it for 1-2 days.
2. Crush
The soaked coal slag should be crushed. You can use your feet to step on it or use a stick to crush it. The goal is to break it apart.
3. Sieve
Crushing the coal slag is not the goal; the goal is to sieve it.
Sieve the crushed coal slag with a mesh screen. It's best to use screens with both large and small holes to separate the large particles from the dust.
The large particles can be used to line the bottom of the flower pots, the medium-sized particles can be mixed directly into the potting soil to improve the soil structure, and the fine dust should be discarded as it can easily cause soil compaction and should not be used.
Processing coal slag is simple, but sieving can be time-consuming. If you don't want to go through the trouble, you can simply use a fine-mesh screen to remove the dust and keep the granular coal slag for planting flowers, which is relatively simpler and more convenient.
For lazy people like me, who are obsessed with green plants, I always just soak it in water, crush it, and sieve the granular soil, discarding the rest.
