Clematis and solanum

i have added trellis to the side of my shed for them to climb up. i will just be weaving them through as they grow.

Which Solanum have you got the purple or the white?, If you want them to grow over your shed they would be better into the ground if you can as to get sizeable growth they want root space, they would be very restricted in a trough, also what Clematis have you bought? and do you just want them to grow against the shed or up over it? The purple Solanum would not need tieing the white one would,

A word about clematis - they like a deep root run so they can keep cool, so your container needs to be a minimum of 16 inches deep and shaded. Rule with clematis is feet in the shade, head in the sun.

Thanks. the solanum is white.
so both are deep rooted, I need a rethink on position.

I dont think I would plant solanum in a trough because as others have already said, it can become a very big plant with many thick stems and will need more root space than a trough will give it. Mine is in flower now and is 12 feet tall and 12 feet wide and would probably be even bigger if I let it

The White Solanum Jasminoides Album, Any well drained soil will do plant in full sun, If you google it there are some Lovely photographs of it which show you how it will grow, I have just planted one to go over the roof of my arbour where there are three or four different coloured Clematis, flowering at differenr times. They should look lovely in amongst the white flowered climber. Good luck.

The clematis won't need tying, but it will need a THIN trellis or something. It's a twiner and will twine itself round its support.
When you plant it, you need to remove the shop cane and twine/fasteners, separate the clematis shoots and gently spread and tie them temporarily to the support. They'll twine their way up with a bit of directional help from you and later you can remove the temp' tie. Plant AT LEAST 4 inches below soil level.

if I plant it 4 inches below the soil should I remove any leaves that will be covered, as it's only a small plant or should I repot it and let it grow a bit more first.

If it's a small plant, but with good roots, then plant it and yes,I would remove bottom leaves, but if you don't, it's not a problem as they'll rot away anyway. However, make sure the plant is big enough to be planted that deep. If your young plant is only 6 inches high and you plant 4 or more inches deep, then you may be pushing your luck. :o) I've only ever planted them when about 12 or more inches high.

If you're not happy with roots, or would feel happier with a larger plant, then pot it on.

A clematis, when planted correctly, will shoot from underground so you will have lots of healty shoots come up.

Also, although it must be deep planted, if it has another plant in front of it and thereby shading the base of the plant, so much the better. They really do like to have protection around their roots and base. The top in sun is not a problem.
