I’m Anna. I live in England . I have big monkey puzzle tree in my garden and it looks like it’s dying. We moved to the house a year ago . Last year we had very dry summer and since then we noticed that more and more branches are turning brown. We tried all sorts of fertilisers and it doesn’t help . It’s beautiful tree and I don’t want to loose it. If you could give any advice what to do I would be very grateful. Thank you.
According to Wikipedia Araucaria araucana, aka the monkey puzzle tree, "prefers temperate climates with abundant rainfall". So you could try giving it an occasional soak drying dry spells. I wouldn't bother feeding it as any but the most meagre soil should contain sufficient nutrients for an established tree. Try to ensure that any rain that does fall in the vicinity of the tree is able to freely percolate down to its roots. So there shouldn't be a load of other plants too near the tree that might compete with it for water. And, ideally, there shouldn't be hard surfaces near the tree that would act as a barrier to water reaching the soil. I work in a sheltered housing scheme garden in north London that had a lovely mature mpt. It was surrounded by tarmac and, like yours, had quite a bit of dead wood, but overall didn't seem in too bad health (until the residents, in an act of mindless vandalism, had the thing felled).
