A quick inspection of a few trees has brought these issues to my attention.
First up are woolly aphids on a Scots Pine. Only on one pine at the moment but I have given it a spray. I think this is the earliest I have ever had them on any tree in my garden.

A few trees were showing signs of mildew. A crab Apple and a Wild Pear.

All have now been treated. I keep a few spray bottles of insecticide and fungicide at hand for some spot spraying. On the bright side, I checked all my Maples and there wasn’t a black fly/aphid in sight 🙂

The general health of the tree is very good. It was repotted in the Autumn and spent the Winter in the poly tunnel. The problem with the rust is that it seems to cause the tree to throw the odd branch. Here’s an example.
Guess I’ll keep trying different fungicides and keep my fingers crossed.

I lifted the next one in and was amazed by the back budding on the trunk.
I set about doing the same process as with the first one and noticed one branch that looked weak. No buds had opened and I just assumes that it had been knocked and a crack had dried out causing it to suffer and die. On closer inspection I realised that I had a visitor! Little fecker was helping himself to the nice new tasty leaves.

A catapillar of some description. If it helps you identify it, when you squish it, it’s green on the inside 🙂
