White fly

m13r13c13

Yesterday my partner was doing a bit of weeding for me while I was at work. He text me to tell me that my lupins were covered in the little blighters.
He found some spray in the garage, don't have a shed, so garage has been made into my storage for the garden, and sprayed them with it. I didn't even know I had that spray.
Went to have a look this morning and they are all over my lupins but no where else. All the other plants near to the lupins have not been touched by them.
Is this usual on lupins? and has anyone got any suggestions on how to deal with them?
The worse one has now been cut down to the ground and the other two are still standing. They don't seem to be as bad so I have left them and just cut out the worst covered leaves and flowers.
Sorry for waffling on, my partner is always getting at me for going round the houses instead of getting to the point.

there is an aphid (and they look like white fly - but are a bit bigger) and they attack only lupins - completely smothering the plant - so it looks grey all over - i am afraid that if they have gone that far - the plants are suffering badly.

the only thing you can do is to chop off every infected bit of the plant and bag up and burn immediately

the plants may not recover

i have collected a small amount of lupin seed this year - if you need to replace your plants - contact via my website

Thanks for the info.
I will have to cut down the other two I think, although they are not as bad as the first one I cut down. I put that one in the brown bin that the council collect and they have already been. The spray that my partner used did kill them so will it be okay that I didn't burn them?
I did manage to save some seeds before they took over the plant, will they still be alright for next year?

i would think that the seed would be ok to use next year

by chopping off the less infected plants - you stand a better chance of saving the plants - so i would do that as soon as you can

baging up and putting in the bin is ok - just tie the top of the bag up tight - so the aphids don't fly off

Whats wrong with an Aphid spray? Once the B*****s have dropped off a feed and water should see them recover.

Although not quite the ame, but many people plant a few marigold flowers in a green house, to keep whitefly off tomatoes. The flowers produce a scent which the flies don't like.

It would probably work outside .. you may still be able to buy marigold plants. African marigolds have the biggest flowers, but I think it's maybe the French ones which the flies hate most .. but check with Google.

Unfortunately this does not work with greenfly which the OP seems to have. Lupins are susceptible to greeen/blackfly like roses.
The op could put a peanut holder near the lupins, whils the bluetits are queueing up for the feeder they could well have a Hors Deurve of aphid.

We get lots of bluetits on our feeders but I think they may be too far from the lupins. Have nowhere to hang the peanut feeder close to the lupins.
The jays like it were it is because it gives them the cover they like so I think it will be staying where it is.
May get another feeder for peanuts, one that can be put on tall stand.

Update - Lupins all cut down to ground level, but have already started to grow new leaves and not a sign of white fly to be seen.
One happy chappy here :-)

I have whitefly all over my strawberries and mint. Someone suggested watering with a little washing up liquid in the watering can. Has anyone tried this? Does it work, and does it damage the plants?

I use washing up liqued/water in a spray bottle it works fine doesn't do any damage ..
