Sprinkle a little of this into the pennywort pot and it will never get yellow leaves again

The pennywort had been home for half a month, and I had only watered it without fertilizing, and it even dried out a few times in between. In one month I let the pennywort grow into this state. Why does it look so wilted? Because when the pennywort is newly bought, what is inside is yellow mud soil, very hard, and also lacking in nutrients. If fertilizer is not replenished in time, nutrient deficiency will occur.

The pennywort's root system grows very fast, but it cannot penetrate into the yellow mud. No matter how much you fertilize and water, the compacted soil will still block the roots' absorption. After it goes without water a few more times, the pennywort will naturally become wilted, with yellow leaves and smaller leaves. So that is the reason. How should we treat it then?

Cut off all the yellow leaves, keep only the root system. You can also divide the pot and put the rhizomes into a larger pot, cover with a thin layer of soil, and replace the yellow mud soil with loose, breathable soil to make it easier for the roots to take hold. Fertilize two or three times a month, applying light fertilizer frequently, and do not let it lack water. Pennywort is a plant that loves water, and it also needs plenty of sunlight. That way the pennywort will turn so green it looks black.
