I've seen the photo in a separate question...

1. In pots that size, about another year if you're lucky.
2. If you want it to be six foot tall, you'll need a pot that's two feet deep and at least 12 inches wide.
3. Can't answer that one...
4. Yes, your photos are still sideways on!

Thanks B, I have the pots so may do it. And I once found how to put the photos on correctly - will try harder next time.

There is one thing you might want to consider - the natural growth habit of Weigela is arching - it goes up and arches out, and those branches will be laden with flowers. That might not make it an ideal subject to grow either side of a door...

Thanks again B, I now realise it wouldn't be appropriate in that position. I now need a plan B.

I turn my phone to the left to take pics and they upload correct on Goy its a samsung :)

Thanks D, I'll turn mine similarly and check with friends if it helps.
