Who can tell me the potted method of iris?

7/ 10 garden soil and 3/ 10 river sand are used for the basin soil, and base fertilizer is applied at the bottom of the basin.

Water the soil regularly to keep it moist, but don't water it. Fertilize 2 ~ 3 times in March ~ April. Apply fertilizer once after flowering.

After heavy frost, the leaves turn yellow, leaving only a few heart leaves, keeping the soil slightly wet. At the beginning of March, watering and fertilization promoted the new buds to grow leaves and pedicels.

After flowers wither, change pots every 2 ~ 3 years and combine with ramets.

Before new roots germinate after flowering, 1/2 cut off leaves, dig roots and divide roots, and each plant has 1 ~ 2 buds. When planting, the soil should not be compacted too deeply, and the upper leaves are exposed to the soil surface, and take root after half a month.
