Generally speaking, it's better from October to November. However, the basic requirement is that the temperature should not be too high. This is because root tubers can only be planted after water absorption treatment. If the temperature is too high, root tubers are easy to rot, so low temperature is relatively safe. It can be adjusted according to the specific situation of different regions.
The hole at the bottom should be larger, which is good for drainage. The wall of the flowerpot should be thinner, so it is more breathable. Generally speaking, the flower pot with a diameter of about 18 cm can plant three or five fibrous roots.
You can use a rough layer to put it on the bottom of the flowerpot, so it's easy to drain. The main matrix can be made up of rotten leaf soil, garden soil and sand, and some bone powder can be added to increase the nutrients.
Bury the roots in the sand, moisten the sand, wrap it in a plastic bag and put it in the refrigerator. About a week or so, the water absorption process of the root is completed. However, if the planting time is later and the temperature is lower, there is no need to put the refrigerator
Place the matrix in a container, then place the root of the block down into it. Then fill in the soil, just cover the top of the ball root. The soil covered should not be too thick. After that, it should be watered and placed in a semi shady and ventilated place. Wait for this stage of germination, do not water
