Question

my plant has been in for a year and when it flowers the flowers seem to dry up and crumble do you know why this is thank you Dot

Answer 1

Most often flowering dying off is due to lack of moisture.
Increasing watering during dry spells and adding 3 to 4 inches of hardwood mulch will help in retaining moisture levels.
