Juniper procumbens needles getting yellow/brown was created by vcnsiqueira

Hey guys!

I have two junipers procumbens that I bought in different dates from a nursery and I realized that some needs in the end of branches are getting yellow to brown. I tend to see my plants every day and it's been bothering me because I think this is a bad sign and maybe I've been doing something wrong. I'm new to bonsai, so I should appreciate some advices on that.

The first juniper seems to have more needles in this situation than the second. Interesting to note that the first one I repot in early days of January and do not pruned the roots (more than 3 months now) and the second I do not repot. Both of them I cleaned some weak branches or brown branches inside of the foliage just to get more sun entirely and I also wire them.

They are always outside and in a position they get sun when it's sun. I live in Ireland, so sunny days are not the usual and also it rains a lot. I do not worry to much about watering cause the top soil is always humid (it rains almost every day, here), yet I water the plants every 3 days until the water goes off from the bottom. My trees are all in development so I've been keeping them in large pots (not in bonsai pots yet) and I really do not worry much about watering.

The first one I repot and the soil I've been using there is mix of orchid soil (seramis, pine bark) with some compost with perlite and vermiculite. I really think I need a better soil in the future, but for plants in development I think it's ok (advices would be good in this area). The second one has the same soil of the nursery which seems to be a mix of compost and pine bark.

Thanks for any help

They don't look too bad, the one that is wired is not good though, I would remove the wire. It is not that unusual to get tips dying, I would go over them and cut the tips that are brown. Do not pinch, that causes browning. I do not have this species I don't like the foliage. I would ease on the watering, I have not watered any of my trees yet since October, we have had a wet winter like you, and the trees have never dried out. As for styling I would be thinning the foliage out quite a lot before attempting to wire, this will help with inner budding, there are clubs in Ireland and I would suggest you find one and go along as you will get good help from local growers. I am in Dorset in England by the way, Geoff.

I get a few tips dieing on my junipers as well in spring. As long as there are healthy new growth it is not an isdue. Junipers produce a lot of new buds all the time and needs to thin out anyway. I would not worry.

I think I see a lost branch on picture 7. Posibly from too severe bending. Time will tell.

But overall I concider this to be quite healthy specimens. Not as good as it can be, but quite good.

I'm trying to do the best I can. I've been reading and watching a lot of videos but do you think this is happening maybe because of too much watering?

As I said, I do not water them as crazy because it's always raining and the humidity outdoors is really good. I try to wait some days (3 to 4) and then, watering until water gets off from the bottom holes. But maybe it's still too much.

I'll try to water them less frequently. Watering only after the 2'' finger soil test - if it's not too humid, then I'll water, otherwise no. Is it a good idea to prune this yellow needles? So I can see clearly if new needles start to get yellow?

Anyway, thanks for the advices so far. I'll become active in the forum and ask for more advices in new trees I've been working with

In my experience junipers just love water as long as is up at 10 degrees or more. However it makes sence to keep them on the dry side in winter. Now heat is proboably not far away for you so decreasing watering would be a terrible idea. Now is the time to ramp up.

I live in an area that gets average of 7-800 mm rainfall per year. In summer I water almost every no matter if it rains a lot or not. In winter we are howering at -10 to 5 degrees. I water not more than once a month.
