Steirodiscus tend to make it in a tiny bit of cold which means that you can plant them just a tiny bit earlier in the year than more sensitive plants.

The earliest that you can plant steirodiscus in Normal is March. However, you really should wait until April if you don't want to take any chances.

The last month that you can plant steirodiscus and expect a good harvest is probably August. Any later than that and your steirodiscus may not have a chance to fully mature. If you are starting your steirodiscus indoors then you might be able to get away with starting them a couple of weeks earlier.
