Bearded irises are a stunning addition to any garden. They come in a variety of colors and heights, and they have a unique beauty that captivates gardeners everywhere.

Reblooming bearded iris, also known as I. germanica, is a species of iris that produces two or more flowering cycles in one season. This reblooming variety typically blooms in early spring and again in mid-summer or fall. This type of iris is often planted in public gardens across the United States and Europe. Reblooming bearded irises are a great choice for gardeners who want to enjoy multiple blooms in the same season without needing to replant every year.
Planting Reblooming Bearded Irises
Planting these irises are easy and here are some simple tips, you can use to ensure that your plants will thrive and bloom year after year. Bearded iris rhizomes are best planted in late summer to early fall when the temperatures do not drop below 50 degrees Fahrenheit in the evening. This allows the roots to get established before they bloom in the spring.
The most important tip is to pick the right spot for planting the reblooming iris. They need a location with well-drained soil and plenty of sun exposure. In addition, it is important to add organic matter to the soil prior to planting as this will help aerate the soil and improve its nutrient content. When planting, make sure to cover the roots of the rhizome and leave the rhizome on the soil surface. If you bury the rhizome too deeply, they will not bloom. Lastly, water your plants regularly in order for them to thrive and enjoy beautiful blooms for years to come.

In warmer climates, you can feed your plants four times yearly.
