Help! My girlfriend got me this ficus triangularis for Christmas and since I’ve had it it’s been dropping leaves like it’s a competition. It’s still in its original pot so I’m thinking maybe the soil was hydrophobic or not well aerated and top watering wasn’t giving it enough water down to the roots. Just bottom watered it 4 days ago and it’s still dying faster than ever. I have about 12 plants in the exact location of this plant and they are all thriving but this guy just doesn’t have the will to live. Any suggestions? It’s in a south facing window currently and it gets checked for watering once a week, has been getting watered when soil is dry about halfway. The leaves that do fall get these brown dots but none of the leaves have them while alive… only after they fall.
