You might not be able to see them in this small picture but I can assure you that there are hundreds of aphids making a good living on the leaves of these crocus plants. This was one of many reasons why this particular box was completely cleaned out – with the plants thrown away and the box itself given a good scrub.
Being some distance off the ground slugs and snails haven’t been a bother. But aphids really took a liking to the crocuses and sadly they’ve also migrated onto the brachycome seedlings then onto the verbena.
They really are very sneaky and I have trouble seeing them at first. But once you see one you know there are likely to be more. The underside of young leaves seem to be a favourite haunt. I wonder if the soil I used last year could have been the source of them as when I went to use the remainder there were lots of black flies in the bag – which wasn’t a happy discovery. Needless to say it was thrown out immediately but the damage may have been done.
I generally try to steer clear of chemical remedies so after reading this useful article on aphid control I’ve been knocking them off with a handy cotton bud and will move on to some soap solution if that doesn’t work. It looks like it will be a constant battle of wills though as they multiply at an incredible rate if left alone.
