I inherited a bird of paradise plant when I purchased my house. I believe it's been here for decades because it's very full, tight, wide and tall. Anyhow, the problem is it has like grass and possibly weeds in between the plant. How can I tackle the task of making it look healthy versus letting it continue to look like trash? How do you remove what's growing in between the actual plant without hurting the plant itself? I would like to salvage this plant. Please give me advice.
