How To Grow

Excellent pest and disease resistance

Virtually disease free. Keep an eye out for the Iris Sawfly - a pest whose larvae eat the foliage of waterside irises. They look like greyish-brown caterpillars up to 25mm long and initially eat v-shaped notches from the leaf margins before moving on to eat from the leaf tips downward. This isn't usually too serious and plants can recover, but it's a good idea to encourage predators like birds and ground beetles as well as regularly inspecting plants during the growing season and removing any larvae by hand.MORE

Water if planted in borders

Irises need moist or wet soil so although those planted in ponds will not need extra watering, you will need to keep an eye on them if planted in beds and borders, making sure to water in dry or hot weather as required.

Full sun to partial shade

Position where the plants will receive at least 4-6 hours of sunlight daily in spring/summer.

Clay or loam soil

Loam or clay soil is perfect. Any soil type will suit Irises as long as it is kept consistently moist.

Feeding may be needed

No feeding is needed if you plant your irises straight into a mature pond due to the nutrient content of pond water, but in a non-pond setting it's a good idea to feed in the spring, using a slow release general fertiliser. ?v=1613300718
