blooms on impatients
Thanks for writing. Without being able to see your plants, I can't be sure of why they stopped blooming. Some possible reasons may include: If the plants stayed too wet or too dry for a period; if the plants were fertilized too much; if the plants were stressed in some other way; or if a pest came in and ate the blossoms.
