Rescue my clematis

Hi I am just wondering if anyone can help me with my clematis, I had it for 4-5 years now in a pot outdoor on my balcony as we don't have garden. I have very little idea about plants, just like to have them. With this clamatis I put trellis panel for it because I didn't know it needs to have sticks to help it grow. Anyway it never had many flowers, so a month ago I decided to cut all back and wanted to put the plant deeper because a friend said it needs to be covered, so I ended up cut all. With difficulty and had a big blister in the Palm of my hand trying to get it out from pot. I got it out in the end and now planted it deeper in the same pot with more multi purpose compost, and water it well. Do you think it will grow again or will it due?

Any idea what it is called?

Most clematis will cope with cutting back to about 18 inches but depending on the kind it is, you may sacrifice next years flowers. It may not have flowered very well because of either lack of water, lack of feed, too small a pot, or position.

I wouldn't use multi-purpose compost ... it's too lightweight for semi-permanent planting in containers - I would use a mixture of two thirds John Innes soil-based compost and one third multi-purpose compost.

How big is the container?

Thank you all for answering my question, unfortunately I do not know the kind of clematis I have its one with purple flowers , quite big flowers. And yes I will change the soil to use John Innes soil based compost with one third multi purpose compost. Does this go to all perennial plants in container?

It's what I use as a basic mix. I add generous amount of horticultural grit to the mix for plants than have a need for very free-draining soil.
