How to change the soil and pot of potted plants

1. Use an iron nail to make a deep circle on the wall of the flowerpot to facilitate the removal of the soil ball. If the roots of the soil ball have spread all around the wall of the pot, it means that the nutrients in the potting soil have been almost absorbed by the plant.

2. After taking out the soil ball, break it up and rinse it with water to expose the root system. Then remove the old and bad roots, and cut off the horizontal branches, weak branches, and overlapping branches inside the plant.

3. Before putting the potted plants in the pot, two tiles can be stacked on the water outlet at the bottom of the pot. This can prevent water accumulation and root rot to the greatest extent and facilitate the breathing of the roots.

4. Prepare the soil : There are many materials for preparing the culture soil. You can put fallen leaves, dead grass, straw, etc. in the pit, sprinkle some manure in an appropriate amount to pile up in multiple layers, cover the outside with 10 cm thick soil, and it can be used after fermentation and composting for more than half a year.

5. Spread a layer of nutrient soil at the bottom of the flowerpot, place the plant in the middle of the flowerpot, leaving a 2-3 cm gap between the plant and the flowerpot, fill the reserved gap with nutrient soil, and water it to help the roots take hold.
