Care Guide

Excellent pest and disease resistance

Iris plants are generally free from pests and diseases. If planted in water, be aware of Foot Rot - to prevent this, make sure the water depth is no more than 15cm. If your pond edge is deeper, you may need to plant in pots. If planted in a border or pots, slugs and snails may be a problem. For Slugs and Snails, it is important to keep the area around the plant debris free and as dry as possible, especially at night as slugs and snails love damp conditions. You can use barriers such as egg shells or copper wire to surround the plant to prevent slugs and snails reaching the leaves. It is also a good idea to spray your plant with water which has boiled some garlic in it for around 2 hours. For more serious slug and snail control you can also use specific nematodes that will find the pests and cause them to dieMORE

Water weekly in borders

If planted in borders or pots, Irises should be watered regularly for the first eight weeks or so, and then weekly, especially in the growing season from March to July.MORE

Full sun to partial shade

Irises prefer a position in full sun (6-8 hours of sunlight daily) but will also thrive in partial or dappled shade.MORE

Moist, acidic soil

Irises prefer a very wet, acidic soil. If your soil is not acidic, mix in plenty of Ericaceous compost.MORE

Not required

Regular feeding is not required, however Irises can benefit from a heavy mulch after planting to conserve moisture and prevent weeds.MORE

Prune in Autumn

Trim back in Autumn when the plants have finished flowering, or in Summer if they become unmanageable. Deadhead flowers after blooming.MORE
