hi everyone i am having a bit of a issue i have noticed in the last few days with my spruce see attached photo can anyone help me with whats going on its getting new growth but some of the growth lower on the tree is going a bit brown and dont know why its in a greenhouse is in a well draining soil watered regularly yet all of a sudden its not looking healthy any help would be very much appreciated its one of my favourite being a christmas tree and all

Most conifers need full sun to thrive. Move it outside to somewhere it gets atlas 6 hours of direct sunlight.

They also need to dry slightly before watering. Watering is one thing that can take a long time to master and you may be keeping it too wet. It will obviously dry quicker outside so keep an eye on it.

All your trees need differant degrees of sunlight. They should be out side and not in a greenhouse, I would say thats worse than keeping them indoors in our climate espiecially summer.
The only trees that will have limited benifits are figs who like the humidity.
Hopefully more advise will come during this forum for you.

My first thought was lack of light as well. looks pretty dark in there so unless they get lots more light for the rest of the day I think they will all have problems sooner or later.
Second, closer look I think the browning tips are possibly some sort of fungal infection (bit hard to get details from that photo). Best treatment for that would be...... more light and air movement Fungi thrive in still air and humid conditions but direct sunlight is the best anti fungal treatment there is.

Thank you so much guys after reading what you all had to say i made an emergency drastic move and have cut the cover off the greenhouse and only left the roof to protect the bonsai in the harsh mid day sun and have chicken wired up the sides to stop the cats around here getting in there hopefully with a heap more sunlight as it sits east west so will get the morning and late afternoon sun as well as the wind they will start to come good again i couldn't work out what i was doing wrong now i know seeing most days the temp in the greenhouse was between 35-40 degrees it cant have been good for them so now regular watering and feeding and they should bounce back fingers crossed
