Q.About an angel trumpet
I received my plants via mail and followed directions for transplanting. Today is it’s first day in new pot. Looked great when I first got up now 3 hours later looks sad and droopy. I used miracle gro garden soil on bottom and then mixed in miracle gro potting soil for top. Is the garden soil maybe to much to allow drainage? Not gonna lie I am freaking out here.
From the image, the pot looks a bit large for the size plant that you have.
Too large of a container can overwhelm the small root ball. I would lift the plant from this container and repot into a smaller pot with good potting soil.
Make sure the container has a good drainage hole.
Keep soil moist but not soggy or dry. Give the plant a few days to adjust to sunlight by keeping in a shady area.
