Hi Dutch Ellen.

I lived in Groningen for a year working at the hospital. Had a great time

What I use is horticultural grit which makes a good draining compost and sprinkled on top also aids drainage and stops moss or algae growing on the surface.

a very light grit not your road or gravel grit.

alpine grit is good but hard to find (around here anyway) I went to the pet shop part of the GC and got aquarium gravel. Comes in various grades and colours and is clean.

For some plants I do use road grit, that is the 7mm. limestone stuff. Only for lime loving plants of course. even that is hard to get hold of though, in smal bags.

nigel coad nice to kwow jou liked it in Groningen. I live at the other side of the netherlands, next to zeeland.
I have a question, where can i buy that?

can i use litter box grid instead?
07/12/2012 at 18:52

That is cat litter??-would not think so

No, it tends to fall to pieces when it gets wet and clogs up the compost. The grit is to help drainage not keep moisture in.

I get my grit at garden centres but can also get from DIY stores and builders merchants

Hi Dutch-Ellen, try searching for "tuinbouw grind", which I think means 'horticultural gravel' in Dutch.  Also "moraine grind".  Look for a mix with quoted grain size mix of about 1 to 6mm (1/6) or 2 to 4mm (2/4) although you could get wide range mix (eg 0/8) and sieve (zeef?) it yourself.

I tried to get some earlier in the year from garden centres but everyone was out of stock so I ordered some Westland Horticultural Potting Grit from Amazon - it was £14.99 for 20kg including delivery - a bit pricey but when you take the delivery into account it seems ok.  It'll last me ages.  

It is very heavy tho' - I needed my OH to help me tip it into a small dustbin by the greenhouse.

You can use cat litter-as long as it is the right kind see. Like tescos lightweight lowdust cat litter. I use it for practically almost all my bonsai. The tescos lightweight low dust is made of moler clay which does not break down so is stable, absorbs and is free draining as well.

Horticulture grit from garden centres I put on top of pots , around Hostas

In potting compost I mix pearlite 

22/11/2014 at 14:01
perlite floats when watering if used as a top dressing of sort. it can float when submerging method of watering and when using a watering can, so water slowly and steadily with perlite

You can also use the grit which is sold for Poultry use.  There are 2 or 3 different types  ( at least here in the UK ).  I would have thought something similar would be available in NL.

I use bog standard grit from B&Q. My aloes, palms and cordylines love it. They have got a mix of shapr sand, compost and grit

just to let you guys know, i tried growing some garlic in pure horticultural course grit and it seems to be growing well.

I have been having trouble finding grit anywhere. I have finally found some 10mm at B&Q can I mix that with my compost? I'm worried its to big. Thank you.

Carol - if 10mm gravel is too large for you (which it might be for some purposes), B&Q also sell pea shingle in bags in their builders yard area which is around 3mm-5mm. I think Wickes also sell pea shingle.
