I have a Mulberry tree in a pot and I was advised to repot it into a bigger pot.
The current pot is 52 cm diameter 40 cm wide (21 by 16 inches). I have Wilkinson, Wyevale and Coolings near me, would I be able to get it from one of those?
Also any advice - repotting something this big sounds quite scary.

If it is getting to be rootbound, then you need a bigger pot - but don't go too much bigger as you don't want the roots to be swimming around in lots of spare compost.
The general approach would be to use a John Innes number 3 type compost. This is a particular formula (made by various manufacturers) which contains a higher proportion of soil than the lower John Innes numbered composts. Therefore the nutrients and water retention are better, because this is a permanent planting rather than an annual crop.
Try to plant at the same compost level as the current plant, and add some fertiliser into the planting hole - hopefully others will confirm whether a general purpose fertiliser like fish blood and bone, or growmore, would be best - or whether something more bespoke / single fertiliser would be preferable (I'm rubbish on fertilisers).
No idea about where to get the pot, sorry.

could you not prune the roots and put back into the same pot with fresh soil?,or (my choice) prune the roots and put into a similar sized air pot?
