Petals falling off dahlias

armaghroseAugust 22, 2007

Can anyone help. My pompom dahlias are losing their petals for no apparent reason. Only one flower at a time is affected and the petals can all be lost in the space of a few hours. They are left in a neat little pile on the ground. The remaing part of the plant seems to be very wet once the petals have been lost.

I have looked in the flower while this is happening and cannot see any bugs. I dont think is is slugs or capsid bugs.

Any help/suggestions - gardener from Ireland?

How old are the blooms? The petals will drop off an old bloom just as you describe above, when they have aged beyond usefulness. I don't know of any illness or bug that would cause such a phenomenon, but I don't leave mine on the plant any longer than nearly ripe or ripe stage.
Could it just be age of the bloom?

I dont think age is a problem as the oldest bloom isnt necessarily the one affected, but perfect blooms are. I am guessing that it happens when the bloom is about 10/14 days old (but I will start keeping a record of this).

I have four varieties of dahlias and the plants themselves are no more than 3/4 seasons old (tubers having been taken from older plants)and all are affected sporadically. It almost happens in front of my eyes. I have a beautiful cream dinner plate dahlia and it is heartbreaking to see one of the flowers end up as a pile of petals on the ground in the space of a few hours.

Thanks for you thoughts, much appreciated.

10-14 days is a long time to last on a plant. I have no other guesses other than age of bloom, but do commiserate with your pile o' petals falling before your eyes.

MIne drop off also, after 4 or 5 days. This is perfectly normal. If yours are lasting 10-14 days, that is amazing. I agree with poochella on this one.
