I was interested in this particular thread as my hostas too have been badly eaten by slugs this year. I must admit when I saw the photo of the cactus I thought to myself, somebody doesn't know what a hosta looks like! However, after reading your post I realised that my assumption was entirely wrong. I note, though, you don't include a picture of your hostas so I imagine they are every bit as unsightly as mine are at the moment! Copper pots might, indeed, be the solution, who knows?
Your cactus, though not a hosta(!), is astoundingly beautiful. Goodness, it's huge. I've had one for the past 5 years, very similar type to yours, but, though hardy, hasn't managed to flower yet and it's not a fast grower either.
I see you have it indoors. Isn't it hardy? As for those plant eating nasties, I'm not only certain they wouldn't approach such a fully "armed" potential victim, but being indoors they wouldn't have access to it, I imagine.
Perhaps you could reveal your "tricks" for getting such amazing results with your cactus? PLEASE don't say it thrives on judicial neglect, as I have tried that but mine is still not flowering.
Hi Phaidra, I thought it best to start a new thread regarding the subject of cactus, for fear of seeming to hijack the hosta thread! I'd posted the photo there originally just to..prove that, though hopeless with hostas, I could still achieve a little something!
I'm so glad you like my cactus. Yes, I keep it indoors as it's heavy and too "thorny" to handle. That should, normally, mean no pests could try and eat it but I was totally surprised, just a few days ago, to find a vine weavil impaled on its spines! I think it'd come from the pot of patio roses I'd recently bought and left there before planting out.
As I have confessed before, I'm not much of a gardener but some things do grow despite of me! Of course, I'm not a cactus expert either but what I do is: always keep it on a sunny windowsill; from 1st October to 1st March do not give it even a single drop of water; from March to October I water it weekly, adding some diluted liquid fertilizer with every watering. Perhaps the reason yours isn't flowering is because you don't let it have a dry season? I heard somewhere cacti need a dry spell and then,truly, thrive on neglect.
Hope this helps.
Perhaps people who have cacti and look after them differently could add their comments too?
