I've attached a couple of photos of the leaves on my trees. I only planted them 2 months ago.

Am I not watering them enough, or is something more sinister going on?

I was resisting posting a reply as I really am no expert, but I have had a lot of similar damage done to young leaves on many different trees and I must assume it has been the fault of the very cold temperatures in May and also the direction of the wind which was predominantly from the north. So not only did the very soft young growth have to survive the cold, but the winds must have dessicated them as well.
I would keep an eye on them and see do they improve.

Looks like wind damage, they should recover are you watering them well, its hard to judge how big they are from the picture.
I have a large Chestnut dying from Phyptora (Bleeding canker) check the dark for any discolouration stains like rusty nail running down the bark.

Looks like water stress to me. Sun and wind have dessicated the leaves quicker than the plant's system could get water to it. As long as you make sure that the plant has adequate water at the roots (a really good soak, not 2 minutes with a hose), they should recover fine.

I was wondering if I was watering them properly, seems I havent been.

How often should I be watering them?

I have 2 that around 6ft tall, and 2 that are 8-9ft tall.

The taller ones seem to be the ones with the most damage.
Also, the leaves seem to be worse the higher up you go, which was what made me think I wasnt watering them enough.

If it is a watering problem and you want to ensure the water reaches the roots, you could try the old-fashioned "pipe" method.

Ideally, the "watering pipe" should be positioned at planting time ... but better late than never !

Since they're only recently planted, you'll need to be a bit careful. Dig a deep, narrow, tunnel leading -- at a bit of an angle -- to the roots/root ball. Sink a pipe (an old bit of 4" diameter pipe would do fine) with its base as near to the roots as possible and fill it with water. When the first lot of water has drained, pour in more. It will take a bit of judgement to know how many times you need to refill the pipe, but I'ld be inclined to repeat the procedure at least three times each time I watered the tree.

It's a sure-fire way of guaranteeing that the water (and you can include a liquid feed if/when you feel it's necessary) is actually reaching the roots. As I say, it's an old-fashioned trick, but I've used it for years and it's always worked a treat.

Thanks for all the great suggestions.

I'll make sure I get some more water on them and see how they get on.
