I have put one blue Annual ageratum plant in ea of my haning planters and they are getting moldy in the centers. I live in Massachusetts where we have have rain almost every day for the past 3 weeks and not a lot of sun. My Blue ageratum (1 plant ea) are in the front of ea. pot with 1 verbena and 1 lobelia plant. The other plants are doing great but the centers are becoming brown and turning black.
Can you help with an answer and how to cut them out or should I just take the whole ageratum out. My E-Mail address: [email protected] Thanks in advance for your assistance.
