What size pots for Clematis & Morning Glory?

[Naga]

I will be putting these on the side of the house climbing up the wall on plastic mesh and because I am putting down some decking (I hope) I would like to know what size pots to use and how many I can put in one pot.

It might depend on the size of the rootball of the clematis (and how vigorous the variety) - if it's already in a pot, then one a bit bigger so it has room to grow but not so huge that a lot of the compost is unused during the growing season. Then a slightly bigger pot the following year, etc. I'd probably put 2 or 3 smallish plants in something the size of a half-barrel. Not sure about morning glory... my seedlings died last year *sobs*

That's just to give you something to read til someone more experienced comes along with the proper answers

the thing about Clematis is it likes cool roots and its face in the sun. So a good size pot - if it looks sparse then fill up the gaps with bedding eg pansies. Top with gravel to keep the Clem's roots cool.
