Planting out potted Clematis query

Nollie

I have two potted clematis that are now in rampant growth in my poly so they really need to go out, soonish. The advice is plant them deep (up to 6” deeper than in the pot). My query is, they have lots of growth and even some buds at the base, do I snip off all the low growth below the intended, deeper planted depth, or does it not matter if the greenery is buried?

I'd not worry about burying the foliage

Me neither.

Short and sweet, marvellous, thanks guys!

What types are they?
Not all of them should be planted more deeply.

Hi @Fairygirl, oh that’s interesting, being a clematis newbie I didn’t know that...

Kokonoe Florida x Diversifolia
Durandi Integrifolia

?

I'm not particularly familiar with those @Nollie, but if they like a freer draining soil, they won't appreciate being planted deeper. The integrifolias are the herbaceous ones, so I'm guessing you wouldn't plant those deeply.
If you take a look at the growing conditions they like on that Clematis site [ http://clematisontheweb.org/index.cfm]  you should be able to find out.

Or one of the specialists - Taylor's, Thorncroft or Hawthornes. If @Richard Hodson is around, he'll be able to advise better.

Hmm, both are non-clinging types, which should either be planted deeply or not planted deeply according to which website you read... confused.spain here! @Richard Hodson yes, your advice on planting depth would be much appreciated!

Update. I have received some excellent and detailed advice from the BCS, the upshot of which is that just make sure the crown is covered by around 1cm, don’t plant deep, so thanks for the headsup @Fairygirl.

Apparently it is only Group 2 early large flowered clems that actually need burying in the hope this assists with clematis wilt. Found this article too, which says much the same:

Hi @Nollie- sorry , I meant to reply to you yesterday.
I'd have assumed that the herbaceous ones wouldn't be planted deep, but although I fancy some of them, I've not yet got round to buying any, so I don't have any personal experience of them.
The Group 2s and 3s would be planted deeper in my experience, without any issue, as it promotes new stems from below ground, but the Group 1 types can be different as it includes quite a lot of those needing free draining soil, so it would be a case of checking the individual plant. 
Glad you got some expert help anyway

Thanks @Fairygirl, odd that most clematis websites don’t differentiate and just say plant everything deep.
