B, before entering the pot, wash the flowerpot, put tiles on the bottom of the pot, and put nutrient soil to the edge of the pot for 3 ~ 4 cm. Dig holes with a depth of 5 ~ 7 cm at an interval of 10cm.
C, carefully dig out the cabbage seedlings with bamboo sticks, plant the roots vertically, stretch them in the holes, straighten the plants and bury them.
D, watering the soles of feet after planting.
Step 4: Daily management
