Hello all, we have a 9yr old miniature catkins tree (Hazel, I think) which has thrived in our garden. Unfortunately this year the leaves are all turning brown and falling, even though I have regularly watered it as I have since we planted it. Any suggestions please on reviving it. Thank you.

Hello Seaburngirl. Thanks for replying and sorry its taken so long. As nothing changed in the care of the tree, we think it occurred with those extremely hot days we had and poor tree couldn't tolerate the direct intense heat. However, I have seen new buds appearing so know that it's not dead as we feared.

can you add a photo of the tree?
Has the aspect for it changed? ie removed neighbouring plants that gave it protection form wind/sun etc?
