Which of your flowers are not covered in aphids?

Newbie gardener here - all my flowers are covered in aphids! Any recommendations for flowers that aphids don't like?

Some on my list I haven't yet tried -
Carnations, Yarrow, Astrantia, Red Valerian, Scabious, Nigella, Dill, Orlaya Grandiflora

I'm a newbie gardener too and my mint, geraniums and some others that I don't know the name of are free of aphids - I did have a plague of the little buggers on my rose bushes but found a drop of washing up liquid in a spray bottle of water, helps to get rid of them (you do have to keep spraying daily though).
Also if you find ants in any of your plants - attracted by the honeydew from the aphids - place a few mint leaves around the base of the plant and the ants will leave very quickly.

They aren't on my snapdragons! But I gave up on scabious because of aphids, and while they aren't there yet; they will eventually be on my bronze fennel, so I imagine that it could be the same for dill. Good luck!

Oldie gardener here, if you ignore the aphids nothing happens! And if you ignore them for long enough you'll see sparrows and other small birds will actually lick the aphids off your plants. If you've not seen a sparrows tongue before prepare to be amazed.

I agree don’t stress the aphids. Just plant what you like

Zov · 26/05/2025 15:34

They're not on any of my flowers. I do sometimes get them on Sunflowers (mid summer/late Julyish - when they're big and sturdy with flowering heads.) I have never got them this early in the year.

No aphids here. But my peonies are covered in ants and ai said that is normal.

Gonna try the mint leavea trick though!

I love this!!!
I shall now leave the aphids alone - I actually felt guilty but was told that they would harm my roses (which are in memory of my brothers and daughter).

It worked for me within 24 hours - I got it from Google - good luck

I get about leaving the aphids alone but how do you stop them ruining the new leaves on an apple tree?
Its looking really awful with all the leaves on the ends of the branches curled over, I’m trying not to use insecticides but don’t know what else to try.

Yes, the plants do seem more or less fine despite the aphids, but I'd like to find flowers that aren't as affected by them so I can use as cut flowers. I know I can spray them off, but it's an extra step I'd rather avoid.

@AddictedToBooks interesting about the mint! We do have ants, and they've been farming the aphids (I've let them so far as it's kind of amazing lol), so may give this a go.

They do harm plants. They suck sap out of new shoots and damage them. They can also carry and transmit plant viruses.

Trueloveneverdies · 26/05/2025 17:24

Astrantias and Dicentras all aphid free here!

ConflictofInterest · 26/05/2025 17:25

They do a tiny amount of damage to new growth, generally of weak plants and new seedlings. If the plant is healthy it will shrug it off. If it isn't it's the soil and growing conditions you need to adjust, fighting aphids is pointless outside.

You'll find they are just gone in a short while so you don't need to change what flowers you grow. There's always a big burst of them in May then the birds eat them. I've just looked out the window and blue tits are licking aphids off my roses as I write this. I've always got a vase on the go. I cut the roses in bud and if there are any remaining greenfly I just brush them off with a cloth outside, they usually cluster at the top of the stem and nodes rather than on the petals so you should be able to brush them off without damaging the flower. Usually you'll get greenfly on some plants and not others even within the same species, often the weaker ones.

Thankfully the aphids are mainly on the patch we have let be wild. If they were harming my tree I would buy baby ladybirds from somewhere like this: https://www.greengardener.co.uk/product/ladybird-larvae-with-release-bags

Yes they do work! I collected some ladybird larvae from a wall that was infested with them, popped them on the rose bush, and they cleaned up the aphids really quickly. I just can't be bothered to do that with all my plants! Hopefully the predators will just catch up soon.

You have several options. My favourite (and probably most effective) is to buy ladybirds and their larvae. There's a masive decline in 2 spot ladybirds so the more we release into our gardens the better.
You can plant nasturtiums as a sacrificial plant or you can plant various herbs close to the affected plants, the theory being that the scent of the plant confuses the pests (yet simultaneously attracting beneficial insects). I'd not plant mint in the ground though, it's very vigorous.

MoistVonL · 27/05/2025 08:17

Leave it a couple of weeks and it will sort itself out. It’s not worth the hassle and the blue tits enjoy the feast.

JasmineAllen · 27/05/2025 08:30

There's none on my foxgloves or geraniums. I've been going round with a small paint brush to get them of my young roses 😂

Yes this is what my mum (a keen gardener) said and also what I've read online and on the PictureThis gardening app.
I had noticed that one of my rosebuds wasn't doing much and was covered in greenfly but after I began spraying it with the washing liquid/water solution, it's begun to now bloom.

As much as I feel guilty on the greenfly, I think where my memorial roses are concerned, I'm going to continue spraying - but maybe leave them alone on the border potting plants that I buy cheaply and expect to change next year.

My Nanna had a specific plot for her mint far away from other plants.
I keep my mint in pots and a trough and I'm glad I did as I can see them putting their feelers out already with this sudden (but welcome) rain.

PumpkinSpicePie · 27/05/2025 16:38

I had tons of aphids on my new roses so I sprayed them with soapy water. They've gone now
My geraniums and new geum have got lots of holes. Could be sawflies? I've tried soapy water on them too.

Init4thecatz · 27/05/2025 16:59

Speaking of, anyone noticed an increase in the number on buddleia? I've seen some horrible distorted mottling caused by aphids this year.
