My Yellow Trumpet Tabebuia Sapling’s Leaf Tips Are Browning, What Am I Doing Wrong?

I recently bought a tabebuia sapling to use for a living urn, and the tips of it’s leaves are browning and progressively moving down each leaf. I am growing it in Entisol from the Florida Central ridge, giving it about a cup to two cups of water a day, keeping it indoors during the winter in ~80 degree weather, and using a plant friendly bulb to provide it light for 12-16 hours a day. What am I doing wrong?

As long as you have not fed it, or changed its soil, then it is likely overwatering. This will lead to infection, and browning leaf tips. Make sure, indoors, that the soil in the container is allowed to dry out between 1/3 and 1/2 down into it before watering again. This may not be on a schedule. You will need to manually check soil moisture.

Along with correcting watering habits, it may be a good idea to treat with a fungicide. This can help get rid of the infection.
