Why is my plant yellowing from the bottom up? So I have a Pimelea Magenta Mist, it’s native to victoria, and i’ve been keeping it inside my greenhouse during winter. It’s been fine and have a lot of new growth on top but recently all the bottom leaves have started yellowing and with observation over the last couple weeks, the yellowing just keeps getting higher up the plant. I recently fertilised it to try and fix the issue and it doesn’t seem to have made a difference. Any advice?
