Just purchased this plant and repotted. Two leaves has wilted and I have yellow and brown leaves. How can I reverse this wilting process. Should the root ball be under soil. Is it too much sun?
First suggestion: never re-pot a new plant until it has 6 weeks to adjust to its new home. Second suggestion: Your new container must have drip holes in the bottom and be only a few inches wider and, or, deeper than the original container. If the container is too large, the soil stays too wet, the roots rot, and the plant gradually dies. The root ball needs to be covered with soil. This plant needs medium light, never direct sun or the leaves will burn. There is a product called superthriveSuperthrive combines vitamins and hormones to encourage plant growth both above and below the soil line. It's not a plant food so it needs to be used in addition to your regular plant food; the two can be used at the same time. Just put a few drops into your watering can & that's all that's needed to improve the health & appearance of your plants. If your plants are in real trouble, add about 10 drops per 2 gallons of water. SuperThrive works best when the soil is dry. that you can read about in the Glossary of the website. It is full of vitamins and nutrients that might help your plant get better.
