Hello! My name is Cindy, I’m a bit newer to growing plants and my first is a mango tree. It’s only a week or so old, and it’s grown to about six or seven inches now. But it won’t grow upwards, all of its energy is going into one specific leaf which is now as long as the stem. Google tells me to trim it, but I don’t want to accidentally kill the plant. The picture I provided is from two days ago, that longer leaf is now as long as the stem and a dark green.
