Can You Grow Irises in Pots?
Irises are beautiful, hardy flowers that bring bright color and intricate designs to gardens and flower beds. But can they be grown in containers and pots? The simple answer is yes, but there are a few considerations to be aware of before you start.
Requirements for Irises in Pots
In addition to regular light, water and food, here’s what you’ll need to give your irises their best chance for success in a container:
- Well-Draining Potting Soil: Choose a quality, well-draining soil, or make your own mixture with 2 parts potting soil and 1 part coarse sand.
- Large Container: Irises are root heavy plants and require a large, deep pot. Choose one 20 inches wide and deep. Also consider one with drainage holes to prevent waterlogging.
- Location: Place in a sunny spot with temperatures between 55°F and 85°F.
Caring for Irises in Pots
- Check your irises for water every day. A good way to check that the soil is moist is to stick your finger in it up to the first knuckle.
- Fertilize your irises every four weeks with a high-nitrogen fertilizer such as a 20-20-20 mix.
- Deadhead the flowers as they fade to encourage new blooms.
- Repot your irises every two years for maximum flowering.
Keep in Mind
Irises are moderate to heavy feeders, so supplemental feeding and regular fertilizing is essential. Even with the added care, irises grown in pots will likely not bloom as profusely as those grown in the ground.
So, the answer is yes, you can grow irises in pots. With the right location, soil, size of container and care you can give them a comfortable home.
Happy gardening!
