    I think you need to create a fan shape with bamboo canes to separate the stems and give it a helping hand to the trellis. Or use some wires on the fence. 
    But do bear in mind that that size of pot will not support a very big plant and it is almost impossible to repot once the growth get going without breaking some of the main stems. Although I applaud your optimism clematis do not do that well in pots - they like a cool root run which is why they are better in the ground. And montanas are particularly vigorous ……….

    That pot may be OK for this season but better to see if you can find one at least twice the height and width and plant the clematis in it at least 4"/10cms deeper than it is now.  Montanas are very vigorous and need training sideways as Hogweed says so go to a good DIY store and buy some vine eyes and garden wire and tensioners.

    Screw the vine eyes into the fence posts at 12"+30cm intervals and then stretch the wire thru them and along the fence to make a horizontal framework below that trellis.  Then snip off those nasty little plastic ties, remove the cane and gently wind the clematis stems along and round the wires.   As you clematis matures - and if you plant it well - it will send up more shoots that can be trained along the wires until some make it up to the trellis.

    You will need to keep it watered all thru the growing season and it will need regular feeds as planting compost only has food for 90 days and your clematis will need it from late winter to late summer.

    Stand some smaller pots around the base to protect the clematis roots from over-heating in summer and freezing in winter.

  • How many hooks and tensioners would i need if i were to do 2 levels of wire along the entire fence? I would also like to use it for my ceanothus...there are 4 posts so does 8 hooks and 4 tensioners sounds ok? 2 hooks on each post for 2 wires running across?

    3 rows would be better with the first one just 6"/15cm below the trellis then 2 more below at wider spacing.  You only need a tensioner at each end of the wire rows.   DIY stores sell this stuff in the fencing section and usually cheaper than garden centres.

    A vine eye is a screw with a hoop/loop on the end rather than a screw head so the wires going through the eyes are held away from the fence, thus allowing easy twining but also improved air circulation which reduces disease.

  • Perfect! Thanks that means 6 tensioners in total then

    Jordan, Could you not lift a paving slab and plant your clematis in the ground?
  • I havent checked the ground below but yes i will look at that...

    I gather you are plotting to do something here that is going to really annoy the neighbours few years down the road.
  • Hahaha no hopefully not as long as i keep ontop of it! The fence panel and trellis were the small wooden wheel barrow is they are extending out to that out there back so not too much of an issue.
