I am thinking of ordering these but strangely they do not have any drainage.

I suppose I need to drill some but where would you suggest, how big and how many?

Do I need to cover the holes I drill with anything?

    Hi Chris , i see from the enlarged pics that they seem to sit on corner pads of some kind therefore a half a dozen or so medium size drill holes will allow the drainage to flow out and away from the trough, cover the drill holes same as any pot with crocks or whatever you choose. jobsagooden

    I would add double the amount of drainage holes mentioned. I like to add gravel and vermiculite to the bottom of pots and troughs, then a mix of that and compost then just compost. Top off after planting with a mulch - bark, gravel etc.

    Cheers guys. What size holes would you suggest?

    I would use an 8 to 10mm drill bit.  If the holes are too small they can easily get blocked and plants growing in containers definitely won't like being waterlogged.

     

    A trowel in the hand is worth a thousand lost under a bush.
