What in the world are these? This is my plum seedling and he is pretty small, but all of his other leaves are large and green. However, he hasn't grown any proper leaves in a while, and all he's putting out are these white ones all clumped up. It looks like a flower but it isn't (and also it makes no sense given his age). What's going on?
He is on a south-facing window, so I think he get enough sun. I have other plants on that window and they don't seem to be suffering. I water it when it gets dry to the touch. Could that be the issue? Do plums need more water? Is the soil type wrong maybe? This is just generic indoor plant soil.
I live in Canada.
