Seedling update:Japanese Maple germinated 2 years ago. Growing is much slower than I expected. Several other seedlings perished for unknown reasons. This one died back a bit after last season, and looks like a bit recently as well. Fortunately some buds are breaking and it looks like it's getting started with some new growth.
Jack in the pulpit (
Arisaema triphyllum) germinated about 4 weeks ago. It germinated in warmth, with no stratification, although the other seedlings perished, possibly due to inadequate drainage.
unknown Rhododendron, germinated around 8 months ago, and still barely 1" tall! Quite a bit bigger than the seeds which were the size of a speck of dust. (pictures back in August). These germinated easily in a warm, moist, soil-less medium. The challenge is keeping mould and fungus growth down. I used 50% peat, 25% perlite, 25% vermiculite, and cooked it in the microwave in attempt to kill pathogens. I'm getting a bit of alge and moss growth, but nothing too serious as to impact the seedlings.
Tomato and Watermellon, these were quick and easy to germinate
