pure pumice?

[KathyM]

I didn't know you could get pumice at Ikea, I might have to give it a try.

My mum tried to buy some online and ended up buying lava dust instead. I'm not sure if that's going to be useful for anything plant-related. My dad reckons it will be good for making wargaming terrain, so maybe it will end up as that.

Now getting geared up to do a mass repotting trying different mixtures and will be keeping an eye open for more Tesco pink cat litter in case they have started to stock it again!

I've been out of the loop for a while so wasn't aware that Tesco don't have that particular cat litter any more. When did this happen (if you know)?

Tesco have it back in stock now, Marise.

Bob Potter still has bags of pumice, although his nursery is closed, he can bring it with him if anyone is going to any of his talks. From memory, it's about £10 for a large sack full and needs to be ordered in advance. I've been growing Haworthias & Gasterias in 100% pumice for the last two years, results are much better than anything I've used before.

Thanks Diane. I'll look out for it next shopping trip.

I also bought some proper pumice from Specialist Aggregates. So I've been doing a bit of researching to find out the differences.

May I ask which grade you bought? Their "horticultural gravel" grade seems a bit large, whereas the crushed pumice looks a bit bright!

Thanks.

Hmm deep open quarrying is environmentally friendly?

Looks like I put my quotes in the wrong place - the fragment you reproduced was not mine. Anyway, I wasn't aware that Specialist Aggregates mined pumice in open-cast quarries. I wonder where other suppliers get their material from?

Apologies if I gave the wrong impression. The quote was yours. The pic came from the intro page of the website of Specialist Aggregates. I didn't investigate further, especially as they implied collection only.

I doubt they themselves directly extract.

I got the "pumice crush" and also the "pumice sand". The pumice crush is still a little on the large side and is graded very well so all the bits are uniformly sized. I mixed it with the sand. It is still usable but would be better if smashed up a bit more.
