Q.Stunted Trumpet Plant
I have had these plants for 4 years and they have only bloomed once. They are the big flowering Trumpet plants. Would you have any suggestions to make them bloom? I am attaching a picture. Thank you. Terry

They prefer full sun or partial sun to perform their best. They may need more potting soil and a larger pot by now. Be careful if you decide to plant them in the ground (or if they start to propagate from seed when they flower) as they are very invasive here in Fort Worth and extremely difficult to get rid of. I have been trying to kill some vines for the last 20 years organically and may now need to use some heavy duty chemicals.
