I bought a Bucida Buceras and a Jacaranda for indoor use. They came and were both thriving for months.
I always thought of repotting them in larger pots which I did and they seemed fine. After 3 days I had to leave the country for a week and I put my boyfriend in charge of the plants.
He said he had watered them after a few days and the soil were a bit too wet when I came back. But…!
The leafs on the Bucida Buceras is dried up and falling off, the tree is still green under the stem but it looks very sad and no new leafs in sight. The Jacaranda is loosing its ferns and is going limp.

Is it because of the new soil?! I used "Ocean forest potting soil". Or is it because they didn't get enough water at first and then over watered perhaps?

Any help is appreciated!
