Can you transplant iris in the spring

A crowded patch of irises is the most common reason for a disappointing show of flowers. If you’ve experienced a disappointing flush of iris blooms this spring, then it’s probably time you divided your iris rhizomes.

When should you divide your irises? 

Irises should be divided every 3-4 years.

How to transplant irises

The best time is about six to eight weeks after their expected bloom time. You should use this timeline even if your irises have skipped their blooming period this year. So for irises that would have bloomed in May, you can start thinking about dividing them in early August.

One word of advice though: avoid dividing your irises too late in the growing season.

This is because you want them to have enough time to get established in their new space well before the arrival of cold weat
