One of the most important things to provide your Bearded Iris with is full sun. This perennial is sun-loving and requires a lot of sunlight to grow healthy and bloom during the blooming season. Although it can also adapt to partial shade, as we’ve mentioned above, it may produce fewer blooms or become more sensitive to one of the many diseases it is susceptible to. So, if possible, provide your Bearded Iris with as much sunlight as possible every day.
Another thing that you should do to ensure that your Irises are thriving is to provide them with nutrients. We recommend applying a low-nitrogen 6-10-10 fertilizer around your iris flowers in the blooming season. However, make sure you don’t apply too much fertilizer because this may lead to increased foliage but at the expense of blooms.
Pruning is also necessary. You can trim back foliage fans to about 6 inches in the fall season to make your outdoor space look tidy. Pruning is particularly essential to reducing the leaf surface area that may host various fungal diseases or caterpillar eggs. After removing foliage, do not use it as compost. Destroy it or throw it away to avoid spreading diseases to your other plants.
