Large tub/tank to soak large pots - X-post

I have one of these

It would be good for what you need.

Also consider a wetting agent and watering them from above. In order to get water into a dry pot I sometimes use a couple of drops of washing up liquid to a watering can of water. Possible not recommended for continual use

You can purchase horticultural wetting agents

Random example (possibly not the best product or price)

Also farm suppliers. When my kids were small, I bought an animal feed/water container at a county show, it was (very) solid polythene, round, about 4 foot diameter and 1 foot deep. Not silly money. Served as a paddling pool for several years.

Cat litter tray?

I have had a plasterer's bath for about 20 years - sits propped behind the greenhouse when not in use. Have used it for a dozen different purposes, one of which might even have been mixing plaster. Invaluable, and fits your bill perfectly I'd have thought.

Interesting thought.

Our largest is 12 x 16 though, so too small.

Thanks - something for feeding large hungry animals should probably have the capacity.

Now to find the nearest farm supplier.

Intresting.

Looked it up at Travis Perkins and they want £40.

Probably find it cheaper elsewhere.

Just noticed it is 41 cms wide so barely large enough.

I would prefer a bit of extra room.

You couldn't fit a 40x40 cm pot in that, well not by my maths. You would need something at least 57 CM in dia.

Yeah. Need to work from the diagonal.

Well spotted.

Wooden frame with plastic sheet over it? I bought a couple of meters of

Kiddie paddling pool every time. cheap and replaceable. Brian

Now looking for a fold up (not blow up) one and Argos has the ideal one but out of stock everywhere.

It may not be the best time of year to shop for a paddling pool.

Then again demand may ease later in the week when it cools down and starts raining.

Missed the OP, but it doesn't need to be a rigid container for what you want to do. A heavy duty refuse sack or an old compost bag will do, provided it's got no holes in it of course. Put the pot in the sack, loosely tie the neck around the stem of the shrub, and fill with water from a hose or a can etc.

David formulated the question :

Old plastic dustbin, old wheelie bin, a rigid pond liner, dig a hole, line it with plastic and fill with water.

Most budget friendly: a rubble bag. Budget friendly: extra large flexible builder's bucket But... are you sure you can lift the thing afterwards?
