My Rhubarb was looking great, but then suddenly some leaves started to go shiny (especially on the underside) and curl up, it now looks very sick. Now a similar thing has happened to the spinach nearby. The spinach leaves are thickened, mottled and discoloured.
Does anyone know what might be causing this and how to get rid of it?

Hi Julia,

It sounds like you may have a problem with thrips. They often attack vegetable crops amongst other things and can cause the shiny leaf effect and the other symptoms you have described.

You can use an organic spray such as Grosafe Enspray 99 spraying oil. You can buy it in either a ready to use bottle or as a concentrate and mix up as per recommended on the label.

Spray in the early morning or evening to avoid your plant getting burnt in the harsh sun and to help with our bee populations. Make sure to spray all over the plant including the underside of the leaves.

Good luck, I hope you get loads more vegetables! 🙂
