    I’ve had 2 die in the last couple of weeks. One for no particularly apparent reason – it was my main plant that I put my caterpillars on. It had bits that looked unhealthy for a while and then I gave it some fertiliser and it came back and then couple weeks later it just died completely almost overnight. The other one was the first plant in the garden to get aphids on it – I think it may have got overloaded with aphids before the parasitic wasp and the ladybirds arrived. My garden is under siege from aphids, far more than last year possibly due to the extra heat. Ladybirds are only just starting to build up and the parasitic wasp is struggling to keep up with the reproduction rate. Normally what happens for me is the aphid population rises about this time and then the parasitic wasp and ladybirds take over. But that’s taking a bit longer this year – hope I don’t lose any more plants!

    Thanks everyone for the responses! I will update the member in Warkworth.

    Susan, if you do manage to get seeds then I would certainly be interested in getting some if possible.

    Thanks,

    Thanks. I will pass that information on. We’ve come to similar conclusions to Dane. Thanks Jacqui for the other ideas. I will suggest that we get a few people doing the online course.

    in reply to: what nettle type? #53303

    Stefan Olson
    Participant

    @Roy,

    I’m also on the North Shore (Torbay). I recently planted a ferox nettle plant and soon afterwards for the first time ever I saw a red admiral on one of my buddleia. Don’t know if that is a coincidence or not! In order to attract them I think you need a combination of nettles and food plants, assuming they are in/near your environment in the first place. I didn’t think we had reds here, but clearly we do :-). Yellow admirals have been seen in the Awaruku Bush area, so somehow they are holding on against the wasp plague.

    I am working with the Awaruku Wetlands group to set up some nettles and a butterfly garden in the wetlands/Long Bay reserve. I also know there are others here on the shore with nettles.

    If you are further south I know that there are red admirals around Birkenhead area as well.

    I am basically trying to plant ferox, urens and australis. There is a lady near me who has a butterfly house that I will probably end up trying to raise the butterflies in, in order to try and avoid the massive wasp problem that we have where we are.

    If you need any help, happy to try and help.

    Turns out that Catherine lives just down the road! I’ll be picking her up so you’ll have at least two people there to sell the 200 plants to 🙂

    See you tomorrow!

    Hi Jacqui,

    I’ve just emailed Catherine. I maybe able to pick up her up, or if there are others going, I’m happy to join a ride.

    I’ve got six cuttings of my perennial wallflower I gave to you last year, would you like me to bring those for the plant sale?

    Hi,

    I’m in Torbay and have seven buddleia available in small pots. One is white, there are a couple of the longer flowered purple ones and the rest I’m not sure of. Pick up only.

    in reply to: Butterflies land & lay eggs but nothing comes of them. #51336

    I’m just south of you in Northcross. And I have plenty of eggs but no caterpillars. I haven’t seen many wasps around but since I’ve seen a tiny caterpillar there one day, but not the next, I’m assuming wasps are eating them.

    My solution is little mesh bags that you can get from a two dollar shop. I put them over the top of the end of the swan plant branch, moving caterpillars if necessary and it stops the wasps from getting in.

    I’ll be starting to do that again from tomorrow. I use really tiny bags for the eggs And then increase the bag size as they get bigger so I know at which stage I’m looking.

    Yes, it took me a while to figure that out, but that was the conclusion that I came to. I’m already losing caterpillars now, presumably to wasps. Looks like I need some protection already…

    Wanganui, but they have a very good website that allows mail order. So I just keep ordering more plants 🙂

    I’ve got 7 plants from cuttings I need to give away – three different varieties I think: white, yellow, long flowered purple. But be aware that there is a weevil which is just starting to affect my plants (in the ground, not these ones) and ultimately will destroy them. I’m on the North Shore

    Hi Dane,

    Since being in Auckland I have moved three times so haven’t really got a feel for how well they grow yet. They don’t appear to be quite as prolific as they were for me in Palmerston North, but maybe I just haven’t given them enough time to settle in yet.

    I did find the dreaded weevil when we moved from Bayview to Northcross but it’s not clear to me whether it came from Bayview or is here in Northcross. Either way doesn’t seem to be a problem at the moment.

    We are just restarting our garden from scratch so hopefully in another year I will have some decent flowering buddliea 🙂

    Where are you based? If you’re on the North Shore of Auckland I have some plants you could come and take cuttings of.

    I’d agree with Richard. My experience is that they need to be moved to a larger pot or in the ground fairly early on. I have noticed that some of the self seeding Swan plants that I have seem to have a much bushier structure, and I think that’s because if they can expand their roots quickly they seem to put out more branches earlier on. But that is only my observation, don’t actually have any proper data to back it up with. It’s also weird because they don’t actually seem to build a massive root structure. If you pull a Swan plant out from the ground, my experience is generally isn’t that big underground but it obviously likes to spread its roots

    I noticed the other day having moved from Bayview to Northcross that the buddleia cuttings that I brought were looking very well eaten. It turns out that we have the weevil up here (I’m assuming it came from here, as I had no problems before moving). So I’m interested in ideas to save my buddleia next season. I have managed to kill off all the weevils on the cuttings thus far, but as the plants get bigger it’s going to be a much tougher job. Very sad.

    I’d also be interested in the answer to this question, I’m in Bayview on the North Shore. I have no idea if there are coppers nearby, but I am about to purchase some Muehlenbeckia axillaris as ground cover and was hoping that I would also attract some coppers…

    Hi Jacqui,

    Things are not much better on the North Shore. Having got married and moved up to Auckland, I am now living in Bayview, so near to quite a lot of bush, and I would get at least one wasp a week managing somehow to get inside – and two of them have been as far as I could tell queens (although that was a month or two back). The wasp problem is just ridiculous here in comparison with Palmerston North. We are just about to move to another house in this area, I’m hoping that we will be far enough away from this nest 🙂

    Interesting, video but seems a bit cruel – I try and make it as easy as possible for them.

    in reply to: Is it helpful to cut flowers off Swan plant? #28722

    I occasionally give them a liquid fertiliser. However, they are planted below bark and weedmat, and I’m not sure how much of the liquid fertiliser would get through the bark.

    If you have any better suggestions, I would appreciate them!

    Jacqui,

    yes, the monarchs are not very accurate with the laying of eggs – they put them anywhere!

    I had one monarch hatch the other day in the conservatory and it immediately is tried to start laying on the Swan plants in there. Had never seen a male!

    My problem is far too many caterpillars and not enough leaves – constantly having to cull caterpillars, otherwise I have no plants left later in the season, so just want to make sure I can maximise their growth.

    Thanks everyone for your help!

    I put the Caterpillar Castle in the sun and opened it up, and by the time I got back from church they had gone. I have seen at least one of them feeding on the Chieranthus today, so hopefully they will be okay.

    Looks like we now have a few days of fine weather with 13? maximum coming up. Is this a good time to release them, or should I wait for it to be slightly warmer?

    Jane,

    Thanks for your suggestion. I have managed to get them out of the conservatory. Unfortunately, the website says that below 18 ? C wasp activity decreases, it’ll be a while before it is that warm outside – but may be worth trying once things warm up a little.

    I now have five red admirals!

    Bernie,

    Unfortunately very few of my nettles are in pots – all in the ground, which makes it a little bit more difficult 🙂
