Welcome to bonsai growing.
Thanks
shibui wrote:It is normal for the older needles on junipers to go brown and fall off. Any leaves are only viable for a certain length of time, usually 1-3 years, and then the tree has to get rid of them so they loose the green and eventually drop off. Obviously the oldest leaves on the tree are closest to the base which are the ones that are brown on your tree. I do not think you have anything to worry about. You can cut or brush the dead needles off.
Your watering sounds good.
Okay thanks. Where the needles are dying, there is only 1-2 shoots on some of the upper branches to replace those needles but so far nothing on the bottom. What do you know of the Juniper regrowing those needles?

If you want a larger or fatter trunked bonsai the quickest way is to let the tree grow freely (usually in a larger pot or the garden) and it will increase in size over just a couple of years.
Alright cool, i am already trying to picture a way i will shape my Juniper so i think soon i'll start pruning it back a bit. But then again i do want a fatter trunk, you raise a good point!
shibui wrote: Fertiliser: because we water bonsai a lot the nutrients get washed out of the pot quite quickly so fertilising is important. Everybody has their own favorite types but your bonsai is essentially a plant so any plant fertiliser will do. i prefer to alternate several different ferts because they don't all have everything in them so variety will make sure your tree gets all it needs. Powerfeed, thrive, worm wee, chook pellet (Dynamic lifter, rooster booster, etc) osmocote in the mix at potting time are all good. Depends on what you can get and what is convenient to use. Just don't procrastinate and do nothing because you can't decide - just feed it with anything!
I've read around and people are saying high in nitrogen fertilisers are best, what do you think? Any mixture is okay or are certain things in a fertiliser better for it or worse...?
shibui wrote: Are you aware that most bonsai, and particularly junipers need to be outside with plenty of fresh air and sun?
Sure am. I keep it on my alfresco outside. It gets the morning sun directly between 6am and about 11:30am, and therefater it gets a bit of indirect sunlight through the trees. It gets plenty of wind and a bit of rain as it's toward the edge of the alfresco and some rain sneaks its way onto the alfresco edges.
