I was wondering what went wrong with my cucumber leafs?
Could this be viral infection? Thanks.
Thank you for contacting the Toronto Master Gardeners.
The good news is the leaves do not appear to be wilting, which is a sign of virus infection. Cucumbers do require a lot of nutrition so yellowing leaves can be a sign of needing an additional feeding. The link below is a good article from the Savvy Gardening blog that documents some of the more common problems that can affect cucumbers.
