Hey there!
I have a bunch of seedlings between 1 and 3 feet in height that did well over winter. I see some are starting to bud, and I am hopeful, however, I see two of them have white fuzz that appears to be mold. All trees have been in disconnected outdoor storage (to reduce freeze damage) for about 4 months. They are all deciduous.
Picture attached. In the picture, it is concentrated under the bend of the tree.
I think it is obviously because the soil stayed too saturated for too long, but I thought I did an alright job of keeping it not too moist. I think both affected trees are ginkgo, and both were freshly potted with almost no roots after being received last fall via mail.
Anyways, thoughts on what it is and what to do? I put the two affected plants outside to get evaporation going asap.
I will keep investigating, but I was concerned and wanted to start by placing the question here.
I am interested in how your ginkgo are doing overwintering outdoors. I have one about 38 years old that was gifted to me a couple years back by someone who said they kept it in a cold garage but didn't let it freeze. I did a bit or reading and some of it said that because of their fleshy roots not to let them freeze. So it spends the winter in the garage. I am not willing to use it to see if ginkgo would survive mulched in. I know they survive in the landscape in CO.
