Transplanting Iris Bulbs

Before transplanting iris bulbs, it is essential to ensure that they are healthy and free of disease. When you receive your bulbs, inspect them for any signs of rot or mold. If you find any, discard those bulbs.

Once you have confirmed that the bulbs are healthy, remove any loose soil and debris from them. Then, plant each bulb at least one inch apart, with the pointed end of the bulb facing upward. Cover the bulbs with soil and lightly press down to ensure that they are secure.

Choosing the Right Potting Mix

Choosing the right potting mix is essential for growing irises in containers. The proper mix should be lightweight and free-draining, as irises require excellent drainage to prevent root rot.

When selecting your potting mix, look for a blend that contains compost or peat moss, vermiculite or perlite, sand, and garden soil in equal parts. This blend will create an ideal growing medium for your irises, with lots of nutrients and good aeration.

In planting irises in pots can be immensely rewarding. They add color and beauty to any outdoor space, and you have the advantage of being able to move them around as needed. With the right potting mix and regular watering, your irises are sure to thrive.
