    Default neem, soap and peroxide?

    hello all. following on slightly from a thread on dish-soap I found some Neem Oil in a local health food shop, so first off, will this do anything? I've read many posts on Neem but I'm still lost for some reason.

    I've been advised to re-pot. I have some peroxide (going with the 'take no prisoners' route). Is it advised to soak my phal whenever it re-potted? Can it be poured through the pot to aid keeping my little bundle safe?

    Currently I feel I should be doing thus: run water through new medium to clean it of junk, remove orchid from old pot, soak in peroxide until fizzing stops, re-pot carefully with new stuff. how does that sound?

    could I do up a combo of neem and dish-soap? to use as a spray/wipe/flush? I'm not sure which either does - any advice along these lines would be great and sorry for the absolute barrage of stuff I seem to be throwing out! :S

    Apologies if this is covered in a million other threads... its a jungle out there!

    I have read lots about neem oil but have never used it. I thought it was used if you have a bug problem like aphids. For some people it works, for others it doesn't.
    I have used peroxide, pouring it on the plant where there was a problem and soaking the roots. I can say that every time I have used it on roots that the fizzing never stopped. So that may not be the best judgement on when it's been soaked enough.
    I think physan has also been used as a preventive measure. But don't hold me to that.
    You may need to soak the new medium (if it's bark) before using.
    A dishsoap mixture is also used to treat bugs from what I've read.
    Somebody with more experience will come along with better advice.

    ETA: just saw the other thread with all the replies

    For Neem Oil...you mix it with a horticultural soap, plain dishsoap or my favorite murphys' oil soap. The soap helps the neem oil remain "in suspension", or it mixes it in the water better. Once you have mixed it, I use it three ways; 1, I get a soft towel and wash the leaves with the soapy mixture 2, I spray it from a mister when I find a particular spot infested with bugs, or 3, I use it when I water plants to kills bugs in the mix. However you use it; make sure you do not expose the plant to full sun for at least 3 days because the leaves will burn like crazy with this stuff on them.
    Hydrogen Peroxide; I use mainly for crown rot, leaf axil problems and unhealthy roots. With crown rot, drip some into the crown until the bubbling stops then sop up with a paper towel. If leaf axils have buggies my stuff cannot get to I bubble them out, then twist a corner of the towel to absorb extra liquid left down in. And when repotting, severly rotted roots do well after a 10 minute bubble in a bowl of H.P.
    Hope this helps...

    I don't use anything when repotting unless there is an issue.

    I rinse the medium and let it sit wet for a day before repotting. I unpot my plant, inspect for any issues, remove any dead roots and repot.

    I haven't ever used peroxide on my plants. Neem oil does work, but it actually has to come in contact with the bugs you are trying to kill--it works by smothering them essentially. So if the bugs are hiding etc etc it won't really work. As for repotting, I don't treat all plants, just if there is a problem. I do usually add a bit of SuperThrive (root stimulant available at local hardware and supercenters) and PHysan (an anti-bacterial, anti-fungal) to my potting mix. And like Ron, I leave my mix to sit for a day or two, preferably in the hot sun before I repot. Then when I repot, I check for issues, remove any dead roots and then pot it up. Does that help?

    It is the oil that causes the burning, as it blocks the leaf stomata and causes them to overheat. If you use plain dishwashing soap without any oil, it can be used anytime, preferrable is early in the morning, so the plants dry out by afternoon.

    ahh thank you so much everyone - things become clearer with every post! it seems there are so many things to consider, yet at the same time I guess its what we make of it too! I'll try not to go crazy with this... once I know I'm doing things right I guess I can calm it all down a little. routine will help, I'm sure.

    thanks again guys, keep up the beginners tips I know they're helping more than just me!

    Darren,
    It won't be long at all and you'll just kind of develop a sense of things. this forum helps with that immensely as you hear what other people are doing etc. Good luck.

    I'm always learning something new in these forums! I've never used Hydrogen Peroxide. I will try this tomorrow since I have to repot a Phal.

    Whenever I repot, I always soak the medium, cutting tools, etc in Physan20 for a good 10 min. This helps to kill any bacteria/fungus living on the plant (if any). I just do it to be safe--you never know. I've recently started repotting my phals in hydroton. I'm currently soaking the hydroton in Rooting Hormone and a SMALL amount of fertilizer. Some of the Phals are doing great, while other are getting that sad floppy leaf look. I think it just needs time to adjust to the new medium.

    Anyway, if you find you have a bug problem you could try using Rubbing Alcohol (R.A). BUT I read online somewhere that it has to be at a certain percentage (I believe it's 70%, but don't quote me on that). It really DOES work, especially against mealy bugs. I've just applied R.A to a Qtip and then swabbed the area where they're clinging to. I've used an insecticidal soap when I noticed little gnats flying around the plant. They were coming OUT of the medium. After I used the insecticidal soap, I never saw the gnats again.

    So, about this hydrogen peroxide thing. How much do we use and do we mix it with water? Please inform.

    Thanks!

    Hey Jake! Just use the HP straight out of the bottle! This is a 3% solution that you buy at drug stores or big box stores off the shelf. No mixing required. Have fun watching it bubble! ( Can you tell it doesn't take much to entertain me?)
