You can definitely dig up irises and replant them. In fact, this is a great way to multiply your stock of irises and create larger, more vibrant displays in your garden.
To start, it’s important to wait until the foliage of the irises has died back in early fall before digging up the bulbs. This is because the foliage provides energy to the bulbs, which they need to store for the next growing season. Once the foliage has turned yellow and withered, it’s a good indication that the bulbs are ready to be lifted.
When digging up the bulbs, it’s best to use a garden fork or spade to carefully loosen the soil around the bulbs. Be cautious not to damage the bulbs while doing this. Once the bulbs are lifted, gently shake off any excess soil and remove any dead or damaged leaves.
Next, it’s time to separate the bulbs. This process involves carefully pulling apart the individual bulbs, ensuring that each one has its own set of roots attached. It’s important to discard any bulbs that appear diseased or damaged, as these could potentially spread problems to the rest of your iris collection.
After separating the bulbs, it’s a good idea to inspect them for any signs of pests or disease. If you notice any issues, you can treat the bulbs with appropriate measures before replanting them. This will help ensure the health and longevity of your irises.
When it comes to replanting the bulbs, choose a sunny spot in your garden with well-drained soil. Irises thrive in full sun and require soil that doesn’t become waterlogged, as this can lead to root rot.
To plant the bulbs, dig individual holes that are deep enough to accommodate the entire bulb, usually around 4-6 inches deep. Place the bulbs into the holes, making sure that the roots are facing downwards. Space the bulbs about 4-6 inches apart to allow for their growth and spread.
Once the bulbs are planted, gently firm the soil around them to ensure good contact and stability. Water the newly planted bulbs thoroughly to help settle the soil and provide them with the moisture they need to establish themselves.
In terms of care after replanting, it’s important to continue watering the bulbs regularly, especially during dry spells. However, be cautious not to overwater, as this can also be detrimental to their growth. Additionally, you can provide a light layer of mulch around the bulbs to help conserve moisture and suppress weed growth.
Over time, your replanted irises will establish themselves and begin to grow and spread. With proper care and maintenance, you can enjoy a beautiful and expanding display of dwarf irises in your garden.
Digging up and replanting irises is a viable and effective way to multiply your stock of these beautiful flowers. By following the proper techniques and providing the necessary care, you can enjoy an ever-growing collection of irises in your garden.
