Thank you so much for answering!

I don’t really have any nerby, I have at most commercial flower stores, so I thought there might be some books or studies I could hold on until I’m closer to one.

Two of my plants died because of the draining issue before I figured out what the problem was, and a couple just died because they’re annual and had already given fruit, so they are whithering (T_T my babys). As for the other ones, tomorrow I’ll upload some photos of them. I want to share them and I’m sure I can learn a thing or two about them from someone in this community ^^.
