What diseases do we treat?

This fungus lives inside choke cherries, blistering the bark, cutting off sap and eventually coming out as large black "knots" towards the ends of branches. In severe cases it can warp the entire trunk of the tree.

Often hard to spot before it becomes a real problem, the birch bark borer lives under the bark and chews up the inside of your tree. Signs are the dying of the top of the tree, or higher branches losing their leaves too soon.

Commonly found in Pine and Spruce trees, it looks like yellow sap weeping from the bark

Commonly found in green ash trees in older suburbs

Birch and Poplar get this. The bark turns a slightly orange color and then black, and dies in patches, eventually falling off

Mountain Ash trees show blistered leaves - bumpy discoloured spots

Your spruce tree will have needles that pale, turn yellow then brown, usually from the interior of the branch, and the needles will die and fall off leaving only green needles on the ends of the branches

Spruce trees tend to get very fine "spider webs" on the needles, caused by a mite. Needles will turn purple  then brown and die.

These warp the end of your spruce tree tips, eventually turning brown and swollen

Usually the south facing side of your mountain ash tree will suffer yellowing, and maybe even die off, due to a combination of infection and harsh winters
