Help needed with leaf disease

The attached pictures show some plants that we introduced a few years ago. Recently I noticed the leaves have some disease on, I also think they have stopped growing. I’m not very green fingered so I’m looking for help/advice on how to fix the problem
Thanks in advance

 

It looks like a very sickly Laurel.
Looks like it needs a good feed, where is it growing?

 

Front driveway border. Gets the sun, early to late morning.
Will feeding it fix this ? Any particular product ? Do I need to pull the leaves off? I’m worried we are going to lose them.

 

Are they growing in decent soil? Only they look really starved.
The leaf damage is probably insect damage from last year and possibly some fungal damage but its the very yellow leaves that would be my concern, they should be a decent dark green.

Not much is going to happen quickly at this time of the year, but you could rake in a dressing of Fish blood and bone fertiliser at the base and let some rain wash it in before new growth starts in the spring, a mulch of organic matter, would also help if possible.

 

Cheers Pete
The soil probably isn’t as good as it used to be since the drive was changed.
Thanks for advice about raking in some goodness
Do you think I should be pulling the dodgy leaves off?

 

Has a lot of cement been washed into the ground?
You can take off the damaged leaves if you want to.

 

I wasn’t really around when it was done, the drive is mostly tarmac but I guess there is a chance of there being some cement in the beds from the edges.
Cheers for the advice

 

It looks like the start of shot hole disease to me, which is bacterial
I think you'd find information on something like the RHS site, but usually they grow out of it, or you can cut off damaged leaves.
I don't know how to do a link but you could google it

 

Ok thanks

Shot holes in leaves can be caused by anything that damages a young leaf and kills part of the leaf, then as the leaf expands you are left with a hole and the leaf may look as if it has been shot.
I wouldn't take the leaves off they will drop off in their own sweet time.

 

Very weak hedge which is susceptible to diseases . I've seen this before on a hedge I used to trim one end is light green/yellow and as the soil improved it was dark lush green at the other end , soil in the garden was rubbish even the grass struggled .

You could feed it twice a year with chicken pellets or other feeds this will be forever and it may never be as good as it should be. Personally I'd rip it out and plant something that will take poor soil like Yew ( taxus bacca ) and it be a far superior hedge .

 

I've never like the modern idea of laurel hedges, developers like it because it grows fast but it always wants to be big and looks awful when clipped with leaves cut in half.

 

cheap and almost bomb proof and fast growing its not surprising they used so often, you can get them looking good but they'll never look quite as good as loads of other hedges
