Sand?

Would a small bag of sand pit sand do? I'm sure you used to be able to buy this from Mothercare.

Grit would be better

...No Mothercare here....

Can you get grit in small bags???

Definitely go to a garden centre/shop or hardware store bound to get it there, not sure how much though. Why do you want to put grit in the compass bin anyway, I don't put any in mine and I have just empties it out and it is fine.

B&Q have Horticultural Grit in 1 litre bags, 1.6kg but it's £6.95....too much.

Not compost bin but compost for seedlings!

Use pearlite instead of grit much lighter and improves drainage like grit. Obtainable from garden centres.

Yes agree Pompa

I have pearlite and don't like it! It floats on watering and goes brown on the surface of pots - messy and not very controllable....

i can not remember where I last got sand.

Perhaps try a pet shop that sells stuff for fish tanks, they may sell smaller quantities.

I got very small bags of sand and of grit last year from the garden centre. Perfect for bringing on the begonias.

Will try both - thanks.

Oh I totally misunderstood so as you were!

Sand is OK as is perlite or vermiculite

Ps you need horticultural sand or sharp sand not builders or play sand

Actually I have used up play sand and it was ok....not limey. And builders sand left outside in the rain (with a hole a the bottom of the bag) to wash was also usable!
Have finished both now.
But now, I can't carry any big bag, so that's the problem.
