Question by Jacquelyn M: Can switching to organic fertilizer kill plants?
I just moved into a house with a lemon tree and some oleanders. I bought some organic fertilizer for them, but my boyfriend told me that switching from chemical to organic fertilizer can kill plants. I don’t know why this would be the case, but I wanted to double check before I fertilize them.
