Hello! We recently purchased a home and have a mature Monkey Puzzle Tree in our garden. We've noticed over the past few months that it's bottom branches are becoming brown and now a sap or something is oozing from its trunk. We are wondering how best to help our tree? Thoughts much appreciated...
Thanks, Allyson

My sister had a Monkey Puzzle tree in Florida. Thumbs up

These trees do not like damp, soggy soil. They can develop canker which is a fungal disease.

There are several insect pests which may bother your tree: mealybugs, thrips and spider mites, which can cause browning of foliage.

You can mix an insecticidal soap to spray the tree.

Another pest is scale. For something as large as a tree, if it has scale, there are horticultural oils that can be sprayed to control the scale.

(Note: I am sad to say that my sister decided to cut down the tree.)

Oops, I forgot something. D'Oh!
We have an NGA member who has a Monkey Puzzle tree.
I will use the @ to get his attention. Perhaps he can give you some advice.

I've only seen that kind of bleeding with mechanical damage. Looking at your pictures I'm quickly reminded that I'm not an arborist. I don't have the slightest idea of what kind of pests and diseases are prevalent in your part of the world. I don't see anything obvious in the pictures. If you can't find signs of specific mechanical damage, insects or other pests, or any kind of residues or patterning that might indicate specific diseases, I would contact someone in your area who knows trees and has experience with the types of problems that are typical of your area.

We do get browning like that in harsh winters, and water stress (too much or too little) can cause burning and browning. The localization of the browning, and its association with the sap makes me thing there's a more specific vector, though.

Sorry I can't be of more help. Maybe we can find an araucaria specialist around here...

I had a Monkey Puzzle tree (Araucaria araucana) in my garden in California. Monkey Puzzles are mature at about 40 years of age and start producing cones at that point. But, it takes a male and a female tree to produce seeds - mine turned out to be female.

Oozing sap and dying older growth is a natural part of the life cycle of the tree. Branches last about 15 years, die and are replaced by new growth. The 'ooze' is a resin that protects the tree.

Enjoy your tree! They are incredibly unique. When we decided to move, I was heart broken to leave my tree (I had started it from a cutting in 1972). My daughter gifted me with some seeds so I now have a pot of 3 2-ft tall juveniles.

Monkey puzzle trees are definitely unique, but after dealing with the sharp little blades of the dried leaflets for thirteen years I don't miss mine very much. Be careful cleaning up those brown branches. I recommend leather gloves.
