Q.Brugmansia
I had planted this trumpet plant 10 months ago. It was mature at that time. Our region is #9, South Texas. Soil is clay mixed with miracle grow dirt. I’m at a loss wondering why this is not growing well. Or is it a true Trumpet plant?
A morning sun and afternoon shade location is best for your Brugmansia in a warm climate.
They need lots of water to do well, a layer of hardwood mulch can help with moisture retention and keep the roots cool.
Regular fertilizing with a balanced fish emulsion product is important for the health of your plant.
I do want to remind you that a Brugmansia can grow to 6 to 20 feet tall with a width of 10 to 15 feet wide. Also remember that all parts of this plant are poisonous.
The other concern is if your clay soil is holding too much moisture. If the soil is not draining, the plant could be suffering root rot.
