Chamaerops humilis help!

Post by Mario999 » Thu Apr 23, 2020 8:07 pm

After advice from anyone.

I have five Champerops in the garden and all seem to have been blighted by black/brown spots. Some really badly.

I've had someone suggest this could be a fungus brought on by the cold damp weather in spring. Is this correct and is there any way to prevent it any further?

Would better drainage help as my soil is quite heavy? Fungicide?

Many thanks.

Hi Mario.

I have no idea what it is or what causes it, but all my three chamaerops get it through the winter.
However with mine its usually only the oldest ones and those lowest to the soil. I just cut them off every spring.
Sorry i cant be of better help.

Thanks for the reply.

I've had someone suggest a hydrogen peroxide spray, so I will give this a go on the worst effected plant.

If you see the areas they originate from, I'd say it's winter wet that causes it. Better drainage certainly helps, but even on my porous chalk, my chammys normally show some spotting

Seems to be a common problem. Has put me off Chamys a little, maybe because mine are quite badly effected.

I've noticed the same problem with my Chamaerops for much of the past thirty winters!

One year I sprayed a couple of applications of Doff fungicide during the autumn and seemed to get good results with very minimal spotting.

This year no spraying, a very wet winter and a few more spots but to be honest it only affected two or three year old leaves. The previous summer's newly opened leaves never get the problem. I just trim affected leaves in Spring.

Thanks.

All five of mine seem to get it quite badly, even on the previous years fronds.

I'm giving a hydrogen peroxide mix a go to see what happens.

Hello Mario and everyone.

Yes I have the same problem with my Chamy. It's actually very bad. I cut all the lower leaves off every year leaving the crown leaves looking pristine.
Then the following year the same problem. Mine grows extremely fast and end up cutting around ten leaves off every year. I always cut off the suckers as I like the single trunk.

Colloidial Silver is another solution.
