The leaves are lime green, I thought this was normal but as my sunflowers nearby are not doing well I'm now wondering if the soil is the problem.  No flowers so far this year.  We are in chalky soil - Chilterns.

I don't know what it is but if anyone wants to see the enlarged image, I hope this works.... thanks to Little Ann for pointing it out on another thread...

Thanks Salino, I should have said it has got sticky out bits in the centre - sorry about the non-specialist language!

i think its a small magnolia. i think its the one with the white star like flowers. got one in the garden.

I think it looks hungry. Chalky soils are often iron deficient and general low in nutrients. A rose fertiliser with iron and magnesium should help. Could well be a magnolia, they prefer a slightly acid soil and chalky tends to be more alkali, so feeding should help.

Thanks franco6832 and Busy-Lizzie, it does look like Magnolia stellata from images on the web.

Is it worth persisting with this or is it always a battle with plants that like acid soil?  I think I might have three other magnolias, one standard only started getting leaves a few weeks ago!

Magnolia Leonard Messel is OK with alkali soil. It's not as bad as it is with azaleas. You could try seqestrene.

I think it could be a Choicia (Mexican Orange) which requires ACID soil or compost and that is the reason it is not happy. Water the plant with Sequestrin from a garden centre.

This is a Choisya and it doesn't need acid soil. I have one on limestone. Sorry to disagree.

BL's right- choisyas don't need acid soil. We have neutral to slightly acidic clay up here, but it's heavy, waterlogged soil that will make them unhappy. It's a bit of a myth with rhodies, pieris etc. as well  that they need acid - they just don't like alkaline and will grow happily on neutral.

PS -It doesn't look like any choisya I've ever seen anyway!

Lots of choisyas here - rampant they are - Norwich is famous for being on chalk.

At least I got the plant name right!!

08/07/2013 at 10:28

I don't think it is a choisya, it has proper woody branches and I don't think it is evergreen.  I'll give it lots of food and see what happens, quite a few of the leaves are looking brown now so it is on the critical list anyway!

Thanks for solving this one.
