Mum's lupins were massacred by aphids last year and ended up a collapsing soggy grey mess. I hacked the tops off, dug them up divided them with a spade, and replanted, discarding the older woodier bits.
This year - healthy vigorous lupins. I can only assume being rejuvenated has helped them cope with the onslaught of aphids.
"What is hateful to you, do not do to your neighbour".
Mine were attacked last year by those giant American aphids, luckily I did get some spikes of flowers first, but they decimated them. This year, I've had a bit of help from the birds, as Ive been feeding them meal worms near the lupins and they have pecked a few off, my neighbour has been hosing hers every night, but they keep coming back. Neither of us want to use pesitcides, so its going to be a nature battle!
