I've used an oral irrigator Can you tell us which one? I'd hate to get one that was too powerful and damages the plants... The one I got is a Panasonic EW-EJ10A "portable oral irrigator". It is battery powered, and has two switchable settings for the strength of spray. The higher setting ...

Has anybody ever used an air-compressor to blow off insects from plants? Sounds like a plan, but where do you blow them off to? Does this work in practice or just help to spread them around? I think I've mentioned before on here I've used an oral irrigator before now, and because it produces a narr...

Hmmm... Got to say I'm envious! I molly coddle my plants, lavish them with loads of attention, yet this year out of my small collection of sixty or so plants I have at least ten and probably more that seem to be rushing headlong towards death's door... Yours looks great to me. Guess there's a lesson...

I had one which looked a bit like a lollipop on a stick - the bottom part was much narrower than the top after a change in growing conditions. I replanted it with the lower portion (about 1/4 of the total height) completely buried, and it now is stable, and looks like it was always the same diamete...

I guess offsets as well as looking good might also add a little stability in that they effectively broaden the base of the plant somewhat. I think mine must just be slightly feeble specimens, they have to be propped up..! I will have a quiet word with them about producing some offsets...

Yes, this is the big one with hooked spines. It will be about 15 years old and 15-20cm tall. Do you manage to keep it upright without any sort of support? The ones I have seem to want to remain narrow at the base and then get fatter as they grow upwards, which leads to them constantly wanting to fa...

Nice! How big/ old is the parent Iann?

The recommended use is between 1 part peroxide with 2 parts water through to 1 part peroxide with 1 part water Also note that the stuff especially when diluted has a limited shelf life Good job you mentioned that... Checked the bottle, the tiny print says "manufactured 12/20, expiry 12/21"...

I've had problems with peroxide in the past in my working life so I may be medically, physically and emotionally more sensitive. I've seen it used for plant sterilisation in tissue culture alongside chlorine based reagents (not together though!). I think used in dilution your plants would be fine. ...

Steady ..... Even at those low concentrations it can damage skin especially if the skin is sensitive. Trust me .... I have had experience. Wear eye covering as a minimum. Noted, thanks Terry. Can't help but wonder what it might do to the plant then if used neat... I've had problems with peroxide in...
