Unhappy climber

My beautiful trachispernium just doesn’t look very happy! I inherited it when I moved into my previous property so have no idea of its age, it’s never been repotted because it’s always been so happy. We moved her two and a half years ago and she settled in nicely but now looks very droopy, and leaves seem a bit yellow. It doesn’t seem to be that cold at the moment and she’s been fed with no improvement. Any ideas?

 

It won't be happy in a pot.
It's a massive climber that can grow up to 8m x 8m, so really needs to be in the ground.

The yellowing leaves are due to a lack of nutrients - possibly iron, magnesium and/or nitrogen.

If the stones around the pot are Cotswold chippings (i.e. limestone), they will make the soil below quite alkaline. So if the roots penetrate into that soil it won't like it.

Can it go in the ground or can you move it into a very big pot?

 

Can’t go into the ground where it is currently I should have said it’s been in this pot for over 12 years! We cut it right back to move and it has done really well regrowing here over two years ago.

 

Ideally repot it if you can in a bigger pot with a John Innes based compost mix.

If you can't then you could try seaweed extract every 2-3 weeks in the growing season and some tomato feed will help with flowers production.
When flowering is over, stop the tomato feed but carry on with the seaweed until Sept

 

Star Jasmine often looks like that after winter but when the weather warms up it grows new leaves and the old ones drop off.
However, yours has been in a pot for a long time and I agree that it would probably like a new pot and new compost. Do you feed it?

I had one in a pot for years and it was fine. I re-potted it 3 times and I fed it with rose fertiliser every spring. I put a tall obelisk in the pot to support it and I trimmed off unruly bits to keep it neat.

 

Yes we feed it through the summer months, but not in winter. She’s had a feed last week to perk her up a bit!

 

I’ll have a look around for a bigger pot, they are just so expensive though

 

Thank you!
