In fact, it is not a lot of demand in this respect, as long as it grows every 15 days or so in the season of fertilization, fertilizer can buy its special fertilizer.
Its root system is relatively weak. When fertilizing, it should be as far away from the root as possible. It can be poured slowly along the edge of the flowerpot, or the fertilizer can be diluted and then sprayed on the plant surface. In winter, it will stop growing, so it is not allowed to fertilize, otherwise it will hurt.

If it is planted outdoors, it can be fertilized in the same way as pot planting, but it is not necessary to apply fertilizer. Because the outdoor planting can trap insects to solve their nutritional problems, it will decompose and digest the captured insects, and absorb all the juice in the insects. Some friends put some fishy fish and shrimps in front of it. They can let some flying insects gather here, and then they can be trapped by it, so that they don't need to apply fertilizer
They only eat living insects, especially those they catch. There are many friends who catch some insects and feed them directly, but they will open their mouths if they are not digested. And also can't let it excessive "edible" insect, so will let its "mouth" appear damage symptom, its edge will turn black slowly, lose the ability of catching insect.
Well, now I know how to use this kind of grass. I don't need to talk about the joy of raising them. Friends who are good at sharing can recommend it.
