Best Types Of Iris For Container Gardening
The best time to plant iris in pots depends on the type of roots the plant has. Here are some guidelines to consider:
-
Bulbous types of iris, which bloom from late February to June, need to be planted from late September to November. These iris bulbs can also be layered with other spring bulbs to create a vibrant and dynamic container display.
-
On the other hand, bearded, Siberian, and Japanese irises bloom from late spring to early fall and can be planted at any time of the year.
-
These irises with fleshy rhizomes need a pot with at least a 2-gallon capacity and a wider shape to accommodate their root systems.
-
Fibrous rooted irises will also benefit from a wide pot to allow for healthy root growth.
It is important to choose the right pot size and shape based on the type of iris you are planting to ensure proper growth and development.
Planting And Care Tips For Iris In Pots
To successfully grow iris in pots, it is important to provide them with well-draining potting mix and containers. An all-purpose, peat-free potting mix works well for all types of iris. Avoid adding a layer of pea gravel or drainage rock to the bottom of pots, as it can impede root growth.
When planting bulb types of iris, ensure they are planted twice as deep as they are large. Layering them with other spring bulbs can create a visually pleasing display. Additionally, regular monitoring and watering are needed to understand how fast the pots dry out. Water irises in pots when the top 2-3 inches of potting soil have dried out.
Iris plants require the gardener to supply water, nutrients, and sun exposure. Daily monitoring during the hot summer months and as the root system grows larger is necessary. Adequate watering is crucial to saturate all the soil in the pot. Furthermore, regular fertilization is important for iris plants growing in pots due to the frequent watering that leaches nutrients from the potting mix.
Watering And Fertilizing Iris In Containers
When watering iris plants in pots, it is important to wait until the top 2-3 inches of potting soil have dried out. This allows the roots to receive adequate moisture without being waterlogged. During the hot summer months and when the root system expands, additional watering is necessary for iris plants grown in containers.
Fertilization plays a crucial role in providing iris plants with the necessary nutrients. Regular fertilization is needed because frequent watering tends to leach nutrients from the potting mix. Diluted liquid fertilizer is recommended, especially during new growth in spring and after flowering has ended. It is important to choose fertilizers with a lower nitrogen content to prevent excessive foliage growth and reduce susceptibility to pests. Fertilizers labeled for tomatoes, roses, or blooming plants are suitable options for iris plants.
Protecting Iris In Pots During Winter Months
Iris plants in pots may require extra protection during the winter months, especially if temperatures drop below 25 degrees Fahrenheit. Moving the pots to a sheltered location or sinking them in the ground can provide insulation for the rhizomes. Additionally, wrapping large planters in burlap or horticultural fabric is an option for winter protection.
For those who want to bring the beauty of iris indoors, Dutch hybrid iris bulbs can be forced to bloom indoors. These pots should be kept in an unheated garage or greenhouse until green growth appears. Watering should begin when the foliage reaches 2-3 inches in height, and the plants should be placed in a bright spot without direct sunlight. Watering is necessary when the top 1-2 inches of soil become dry.
iris plants are hardy and adaptable, making them suitable for container gardening. With the right potting mix, adequate watering, and regular fertilization, iris plants can thrive in pots for many years. Understanding the specific needs of different iris types and taking necessary precautions during winter months will ensure the successful cultivation of iris in containers. So, why not add the beauty of iris to your container garden and enjoy their stunning colors and elegant blooms year-round?
