Larch - yellow/browning needles

[Tom29]

I've come across this relatively Large larch that has been slightly unloved (I don't know the full backstory) and am tempted to add it to my collection. This will be my first Larch so wondered if anyone would be able to assist me.

Looking at the needles, sorry the picture isn't great quality, there is some discolouration - with several turning yellow/brownish - from the tips.

Based on my experience with other species I would presume this is down to a mixture of sunburn/heat and underwatering.

Just wanted to reach out to any larch experts in case there were some species specific 'red flags' to look out for on a tree.

Mine did that last year. Everything dropped for some reason that I haven't figured out yet. It did bounce back perfectly the year after.
Foliar feeding seems to be a great defoliation method for larches, can't recommend it. They tend to skip a yellow phase and just dessicate.

If you don't do foliar feeding, it might be caused by excessive heat. With under watering the tips would go droopy, so that might be something to look out for.
Other than that, I'm not sure I can help.

This is a Golden Larch, Pseudolarix amabilis?

Based on a quick Google search it definitely has the characteristics of a Pseudolarix amabilis

When we say just "Larch" here, it means the other one, Larix. Golden Larch is a whole different animal, USAg zone 7 & up. Both turn gold in autumn, so you might be experiencing the beginning of that.

Thanks for the info. I will do a bit more research - but as you say, it may be the start of its natural behaviour. The tree hasn't been well loved recently so some watering neglect may have occurred too, contributing to the change in colour.

Its sunburn. End of story
