Q.Mandevilla advice

Zone Sault Ste Marie, Ontario, Canada | Anonymous added on September 7, 2020 | Answered

Good morning, I believe I have a mandevilla that is not doing so well. I have two of them and one seems to be doing ok while the other has some leaves that have turned brown. I’m using these as my wedding flowers in 2 weeks and worried I am doing something wrong. I keep them in my living room which is bright but they are not in direct sunlight ever. I have read conflicting articles saying they like moist soil as they are from Brazil but I have also read that they like to dry out between drinks. They are in pots about 1 ft in diameter with a hole in the bottom. The one not doing well is in rich heavy black earth and the one that is doing well is in more of a vermiculite (lighter and looser). I have been watering about once every 2 weeks when the soil feels dry a few inches deep. Any and all advice appreciated, please help save our wedding flowers. Thanks in advance for your time and knowledge!

The soil in the pot with yellowing leaves is probably not giving the plant what it needs. You should consider repotting that one with a fresh soil mix. This article will tell you what this plant requires:
