I've had this coffee plant about two years and it grew really well at first. I repotted it to a larger pot about a year ago. I have two concerns. First, it has always grown upwards and never got bushy or full like the photos of coffee plants I've seen online. Second, the leaves tend to get brown even when I keep it well watered. It gets moderate sun, mainly in the afternoons. There are new leaves continuing to sprout though, so I don't think it's dying. Should I trim it down so it grows out instead of up? Would that make it healthier? If so, how do I trim it?
