Sowing Advise

Woodland Iris seeds

Germination: Sow outdoors in late fall or early winter for spring germination. Indoors, place seeds in moistened medium in the refrigerator for 6 weeks, followed by germination at a temperature within the medium of 15 – 20 degrees centigrade which takes 3-5 weeks or more, Germination is often slow and irregular.

 

OTHER IRIS SEEDS

For best results, sow onto a good soil-based compost. Cover the seeds with fine grit or compost to approximately their own depth. They can be sown at any time, and germination can sometimes be quicker if kept at 15 to 20 degrees C. We sow most seeds in an unheated greenhouse and wait for natural germination, as many seeds have built-in dormancy mechanisms, often waiting for natural spring germination, hence giving them a full season of growth.
