My Money Tree was thriving and then suddenly I noticed a mushy stem. I took the plant apart and it seemed the bottom soil was giving root rot (despite being a self draining pot). I removed the mushy stem and then repotted it. Seemed like it was doing better, but now I noticed two other stems are getting mushy (I swear I’m not overwatering!!) should I remove the other two stems? There would be two good stems left. Any tips to save this baby?
