I am going to try something new next year for my baskets and pots. Instead of using vermiculite to retain moisture, I am going to try mixing Catsan Silica cat litter grains into my compost instead. Has anybody tried this before and what do you think of my idea?

I dont know really, Sue,surely the idea of cat litter is to absorb liquid, would it go cloggy? Perhaps you could have a go and let us know the results.

Hi Lyn, yes, it does absorb liquid, that's the idea, I'm hoping I will not have to water my hanging baskets and pots so often. Vermiculite is very expensive and I have to order it from Germany. I will only add a handful per litre of compost and mix it well. Will definitely let you know the results.

Try builders merchants for exfoliated vermiculite. It is used as insulation and might be cheaper than from garden centres or pet stores.

just bought 100L bag  of vermiculite from builders merchant, £22 approx.

Just make sure that you make use of the cat litter before the cats do

 waterbutts! Thanks for the tips everyone, but I'm a stubborn bugger, I've decided to try it anyway, I want to see if it works! If it does, I can kill 2 birds with one stone, the cats will have a nice clean litter box and I don't have to water so often!

I'm trying out two different types of non-clumping cat litter in my soil mixes this year for seed propagation, rooting cuttings and for bonsai and succulents.  I read about it on various forums.  For bonsai, someone uses Tesco Low Dust Cat Litter on its own (the red granules - and I'm also trying out the white one ( So far, so good - everything's growing, but it's early days).
