Hi Everyone

I have some broad beans in my garden at the moment that seem to be
growing healthily enough, but they are covered in black aphids and ants.
Should I be worried about this? If it's a problem, what can I do about
it, given that I am doing my very best to garden organically?

Collect some fag ends, remove the paper and boil tobacco in water. Then
spray the nicotine solution on the aphids. Remember to wash off the
solution before eating.
