lol, too long @chilliwilli - must have been in there for 6-12 months.. and it is only a 1 litre pot !
Simply dunking the root balls bare is a fantastic way to help loosen up the roots.. with out having to use your bare hands which roots don’t generally appreciate. This is mainly a case for a plant that has been in a pot for a long time and has less than par soil around its roots. a couple swift dunks will really untangle the roots. This is helpful if you have multiple plants you need to do at one time as the fresh soil will wick remaining moister from the dunk and give you time to get back around to them for their Final dose to even things out. The added bits that make up that solution will reduce some stress.thanks @X15 , that sounds like a good dunk for anyone with aloe growing around them and the time to make it..
you weren't clear about which plants you want us to dunk,
but i wouldn't recommend dunking 'naked' rootballs except if the plant was very rootbound.. if i dip plants then i leave them in their pots and lower them slowly in - and i wouldn't do it at all for any recently potted plants because some soil ingredients, such as perlite, float. I would dunk a plant in its pot of it had dried out too much and the soil needed re-wetting, or maybe if i had fungus gnats and was applying nematodes. Normally though rather than dunk, i tend to leave the pot in a tray of water maybe 1 inch deep for a couple of hours and let it soak up rather than dunk the whole rootball - less likely to cause problems imo.
I used half strength seaweed extract to water the rejuved mother plant after the process.
