Q.My Pepper Plants Have Some Brown Discolouration On The Underside Of The Leaves – What Could Be Causing It?
I have a load of pepper plants in containers on the balcony. They’ve been a bit battered by aphids (treated with soapy water and flour) and caterpillars (removed and thrown over the balcony), and very battered by the big storm we had a few weeks back. They wilted quite badly after the storm, but since picked up again. However, now I’ve noticed some discolouration on the leaves. It’s only the plants that were badly hit by the storm and the aphids (I have some pepper plants on the other balcony that weren’t touched by either), so I wasn’t sure if it was maybe wind damage, or if there’s something more sinister going on. Any advice would be hugely appreciated.
