watering

Iris maackii should be watered deeply and thoroughly every 7-10 days. When watering, it is essential to give the plant enough moisture to thoroughly soak the soil, but not so much that the soil remains waterlogged. Keeping the soil moist throughout the growing season will help to promote healthy growth. Overwatering can lead to root rot, so make sure to check the soil for any signs of waterlogging. If it appears to be staying wet, reduce the frequency of watering or increase the drainage of the soil. In the late summer and autumn, reduce the frequency of watering significantly as the plant enters its dormancy period.

sunlight

Iris maackii is a sun loving plant and needs at least 6-8 hours of direct sunshine each day. It prefers to receive its sunshine in the morning, before midday in order to set a good foundation for the rest of the day's photosynthesis. The plant also benefits from morning warmth and bright late afternoon sun, which will extend its growing season. If it does not receive enough sun, the plant may become leggy and have less abundant flowers.

pruning

Iris maackii, commonly known as Blue Flag Iris, should be pruned in late winter or early spring to get the best results. Trim any dead foliage down to the crown of the plant, and remove any debris from around the crown. If the bloom spikes have died back, cut them down to 6-8 inches in height. To promote new growth, prune any shoots that have grown above the foliage around the iris. Pruning can be done conservatively or more heavily, depending on how much height and fullness you want in the final result. If the clump has become overcrowded, divide into smaller sections and replant.
