Growing irises in containers is a popular choice for many gardeners who want to enjoy the beauty of these vibrant flowers without the commitment of planting them in a garden border. Iris plants are known for their stunning bloom and come in a variety of colors and sizes, making them a versatile choice for any garden.
When choosing a container for your potted iris, it’s important to consider the size and drainage aspect. The container should be large enough to allow the rhizomes to spread out, but also ensure that it has good drainage to prevent waterlogged soil. Placing a layer of rubble or broken clay pots at the bottom of the container can help with drainage.
Potting the iris is a key step in successfully growing them in a container. Use a well-draining soil mix, such as a 50/50 blend of potting soil and perlite or sand. Leave at least half an inch of space between the top of the soil and the rim of the container to allow for watering.
Once planted in the container, it’s important to provide support for the iris plants. Use stakes placed in the soil alongside the rhizomes to avoid damage to the roots. This will also help keep the plants upright and prevent them from toppling over in heavy winds.
Proper care for potted irises includes regular watering, feeding, and pest control. Water the container thoroughly when the top inch of soil feels dry. Use a balanced fertilizer, such as a 6-6-6 or 10-10-10, every two to three weeks during the growing season to provide essential nutrients. Keep an eye out for pests, such as aphids or iris borers, and take appropriate measures to control them.
Replanting and dividing the iris plants should be done at least every two to three years to maintain their health and vigor. This is best done in autumn, after the flowering has finished. Lift the rhizomes out of the container, divide them if necessary, and replant them in fresh soil.

How to Plant and Care for Bearded Irises
Bearded irises are a popular flowering plant that can be grown in pots or in the ground. Whether you’re a beginner or an experienced gardener, these tips will help you successfully plant and care for your bearded irises.
Planting
When planting bearded irises, make sure to choose a sunny position with well-draining soil. Bearded irises need at least six hours of sunlight each day to thrive. Before planting, prepare the soil by removing any weeds and adding organic matter such as compost. Make sure to also loosen the soil to a depth of about 12 inches.
When planting, make a mound of soil in the center of the hole and spread the roots over it. The rhizome, which is the bulb-like structure, should be partially exposed above the soil. Be careful not to completely bury it as this can lead to rot. Firmly press the soil around the rhizome to secure it in place. Bearded irises should be planted in groups of three to make a bigger impact in the garden.
Care
Bearded irises require minimal care once planted. Water the plants enough to keep the soil moist during the growing season, but be careful not to overwater as this can cause the rhizomes to rot. During the summer, bearded irises may need additional watering if the weather is particularly dry.
Feeding is an essential part of bearded iris care. Apply a balanced fertilizer, such as one labeled for bulbs or flowering plants, in early spring and again in early autumn. This will provide the necessary nutrients for the irises to grow and bloom. Avoid using a nitrogen-heavy fertilizer as this can encourage leaf growth at the expense of flowers.
In autumn, after the irises have finished flowering, it’s a good idea to divide the clumps. Over time, bearded irises can become overcrowded, which can impact their flowering. To divide the clumps, lift them out of the ground and separate the rhizomes. Replant the rhizomes in a well-prepared bed, making sure to space them about 12 inches apart.
Diseases and Pests
Bearded irises are relatively disease and pest-resistant, but they can still be affected by a few common issues. The most frequently encountered diseases in bearded irises include iris leaf spot, bacterial soft rot, and root rot. To prevent these diseases, make sure to provide good air circulation around the plants and avoid overhead watering.
Pests that can affect bearded irises include aphids, thrips, and iris borers. Check the plants regularly for any signs of pests and take appropriate action if necessary. In some cases, you may need to apply an insecticide to control the pest infestation.
In conclusion, bearded irises are easy to care for and can provide a stunning display of flowers. By following these planting and care tips, you can ensure that your bearded irises thrive and bring beauty to your garden.

The Basics
When it comes to potted iris care, there are a few basic steps to take to ensure that your plants thrive and flower successfully. Here is a guide to the essentials:
Choosing the Right Container: Select containers that are at least 15cm in width and have drainage holes to prevent the iris rhizome from becoming waterlogged.
Preparing the Container: Fill the container with a good quality, well-draining potting mix. You can also add some rubble or broken pottery at the bottom to improve drainage.
Planting the Iris Rhizome: Place the iris rhizome in the container, making sure to leave enough space for the roots to grow. Position it upright, with the rhizome just below the soil surface, and the roots spread out alongside it.
Watering and Care: Water the iris thoroughly after planting, and keep the soil evenly moist. As the plant grows, water regularly, but avoid over-watering to prevent the rhizome from rotting. Deadhead the flowers once they fade to encourage new blooms.
Support: Depending on the variety, irises may require support to keep their upright form. You can use stakes or cages to provide the necessary support.
Pests and Diseases: Bearded and dwarf irises are generally pest and disease-resistant. However, iris borers and slugs can cause damage. To prevent pests, keep the area around the potted irises clean and free of debris.
Dividing and Replanting: After a few years, the iris rhizomes may become crowded. To maintain healthy plants and ensure continued blooming, divide the rhizomes in the spring. Replant the divisions in the same containers or in your garden bed and allow them to establish before the next flowering season.
By following these basic care requirements, you can enjoy the beauty of irises in a container or in your garden for years to come. Don’t worry if the leaves die back in the winter, as the iris will appear again in the spring, ready to brighten up your outdoor space.
Planting
Planting Iris in a container is a great way to enjoy these beautiful flowers in small spaces or in areas where the soil may not be suitable for their growth. It also provides easy care and maintenance for these stunning plants.
When planting potted Iris, there are a few important steps to follow:
- Choose a container that is at least 15cm wide and deep to ensure enough space for the roots to grow and thrive.
- Fill the container with a well-draining potting mix or a mix of garden soil and compost.
- If your Iris is already potted, gently remove the plant from its pot and separate any root-bound sections. Dividing the rhizomes can help promote healthy growth and prevent overcrowding.
- Position the Iris in the container, making sure that the rhizome is exposed just above the soil line. This will allow the plant to receive enough sunlight for optimal growth and blooming.
- Fill the container with more potting mix, ensuring that the rhizome and roots are covered but not buried too deeply.
- Water the freshly planted Iris thoroughly, ensuring that the soil is evenly moist.
- Place the container in a sunny location, ideally facing south or west, to provide the plant with the necessary sunlight for healthy growth.
In terms of companion plants, Iris can be grown alongside other perennials or flowers that have similar care requirements. Good choices include bearded Iris, tall bearded Iris, and Dutch Iris.
Ensuring proper care for your potted Iris is essential for their long-term success. Here are a few basic care tips:
- Water the plants regularly, keeping the soil consistently moist but not waterlogged.
- Fertilize the plants once a year, preferably in the spring, using a balanced flower fertilizer.
- Divide the Iris every three to four years to prevent overcrowding and maintain healthy growth.
- Remove any dead or yellowing leaves, as well as spent flowers, to promote new growth and prevent the spread of diseases.
- Subscribe to our care guide or consult with a knowledgeable gardener for more detailed care instructions.
By following these planting and care guidelines, you can enjoy the beauty of Iris in containers or pots for many years to come.
Step 1 – Choose a healthy plant, cut leaves back to 6″ (15cm)
In this guide, we will explain the steps for successfully growing and caring for potted iris plants. One of the first steps is to choose a healthy plant for your container. Look for dwarf iris varieties that are known to be healthy and disease-resistant. Make sure the base of the plant is not waterlogged and the rhizomes are firm and plump.
Before planting your iris in a container, proper preparation is essential. Select a container that is at least 6 inches (15cm) deep and has adequate drainage holes. This will help prevent water from accumulating and causing root rot. Stop any diseases from spreading by disinfecting your container before planting.
Once you have chosen a healthy plant and prepared the container, it’s time to start the planting process. Cut back the leaves of your potted iris to around 6 inches (15cm) in length. This will help the plant conserve energy and focus on root establishment. It is important to note that cutting back the leaves too much may hinder the growth and mass production of flowers.
When planting your iris, make sure the rhizomes are planted facing up. This is the ideal orientation for the rhizomes to grow and bloom. For a container planting, you can place multiple rhizomes in the same pot, but make sure to give them enough space to grow. A general guideline is to space them about 2 inches (5cm) apart.
After planting, water the iris thoroughly and make sure the soil is moist but not waterlogged. Irrigate whenever the top inch of soil feels dry. Iris plants require moderate moisture, so be sure not to overwater them as this can lead to root rot. If you live in an area with heavy rainfall, providing a slightly raised mound for the container can help with drainage.
Iris plants are heavy feeders and require regular feeding to maintain their healthiest growth. Use a balanced fertilizer formulated for iris plants, following the instructions on the package. Apply the fertilizer every 2 to 3 weeks during the growing season. This will provide the necessary nutrients for the iris to produce vibrant blooms.
Potted iris plants are susceptible to pests and diseases, so it’s important to monitor and address any issues promptly. Common pests that may affect iris plants include aphids, thrips, and iris borers. Regularly inspect your plants and take necessary measures to control these pests if you see any signs of infestation.
In general, iris plants are relatively low maintenance and can be grown alongside other companion plants. However, if you notice any signs of disease or pests, it is best to isolate the affected iris plants until the issue is resolved.
