Lower Leaves On Cistus Argenteus Silver Pink Are Dying And Flowers Not Blooming

Question

I have had a Cistus Argenteus Silver Pink plant in a container for the past year and a half. This year it has produced an abundance of flowers, but in the past couple of weeks, I have noticed that the flower heads are not opening so much and the lower leaves of the plant are turning yellow. Could you suggest anything?

Answer 1

If the container has not been upgraded it may be time for a renewal. The plant could be rootbound. You can go up one size in the container and add fresh potting soil. Also make sure the plant doesn't have an insect invasion causing the problems.
