I went on one site and it said we would need 1 ton of topsoil to fill it!
Can we put stuff at the bottom of it so we need less soil? Does it need to
be top soil or is multipurpose compost ok?
We are thinking of having a couple of lavenders in it and a hardy perennial
(?) and perhaps something else ... but nothing that grows more than say
...... 75cm wide and 75cm high.
We want things that are low/zero maintenance, provide all year round colour
and flower sometime in the year.
Ideally we'd like to do it in the next month or so .... but is it something
we should leave to do next spring??
Your expert advice appreciated.

Hi, Phil, you don't say where you live ? Regarding the planter, makesure that you have drainage holes in the bottom. If you had some stones or rubble you could put a 20-30cm layer over the bottom, and there is nothing to stop you using multi-purpose compost apart from the cost. Ideally a mixture of topsoil and multi-compost or even just plain Irish moss peat would do but try to put a layer on top of pure compost to stop the weeds. Also its important that you leave 10cm gap between the top of the planter and the compost to give you a watering space for when it's very dry.
