How to divide purple irises into pots and when and how to divide them

Time to divide purple irises

When caring for irises, they are usually repotted every two or three years. There are no strict requirements on the time. You can choose to repot in spring when the temperature is suitable for wound recovery and the survival rate is higher.

The correct way to divide purple irises

1. Choose potting soil

Before repotting, you must choose suitable potting soil. The size of the replacement pot should be appropriate. You need to choose a suitable pot according to the size of the flowers. It should be suitable for the growth requirements at the time. The soil should preferably be loose, fertile, well-drained alkaline soil. The soil and pots need to be dried and sterilized.

2. Remove the pot and prune the roots

Do not water the plant in the first few days of repotting. Then use a shovel to rotate the pot around to make it easier to remove it from the pot. You can then trim off any rotten or overly long roots.

3. Planting in pots

After everything is prepared, you can plant it in a pot. Prepare the soil and plant the irises. Water them thoroughly once and then place them in a well-ventilated, cool environment to slow down the seedling growth and promote recovery. After they grow normally, you can maintain them normally.
