Rhubarb Leaves look like lace
« on: July 13, 2009, 13:36 »
I have three rhubarb plants one at home, two on the plot.

Home plant is on its second year and the leaves look like lace they have been chewed non-stop. I have pellets down for slugs etc etc no visible sign of anything at all. we dont see many birds in the garden thanks to our killer cat. so it cant be birds

The ones on the plot went in this year and are already four times bigger than the one at home

What is eating the leaves ? and why is it looking so feeble  :wub:

I feel like a detective bent over the plant every half hour the neighbours must wonder what the hell i am doing, anything more I can put down, the plant looks a mess

Old tea bags etc etc  :mellow:

My rhubarb leaves have been chewed by something but I thought they were poisonous?

I guess not to old sluggys?

Oxalic acid is the 'poison' in rhubarb leaves but in further research, it seems to be mostly in the leaf blade rather than the green part of the leaves which could be why the pests are eating that part and not dying off as they should.

ours looked lacy too, it turned out to be the hens scratching about around them and tearing the leaves!  We put a mesh barrier around it and the leaves are fine now.

Nope unless I missed it while I was asleep, new leaves come up and then within hours they are the same  :mellow: might have to take some pics

sounds like caterpillars to me.... mind you, you'd expect them to be of huge proportions eating all the rhubarb!
For the latest on the BIG project, read my blog.

I have the same problem, new leaves have been completely shredded, but I have found the Culprit.
  Tiny white slugs, about 1/4 inch long.  I looked with a torch a night, found one of these on a stem and put it in a jam jar with a rhubarb leaf.  by the next morning, the leaf had been severely chewed!
