The "black stuff" probably is a mold and means the tree was being kept too
wet without enough light. You can use an old soft tooth brush to remove the
"black stuff" but you will need to give the plant more light and less water to
keep it off.

Thanks for giving it a name, Billy ! I've done some research on
'sooty mold' and found that it's actually living on honeydew and the
only way it hurts the plant is when it covers the green so it can't
get any light. Since there are no honeydew producing critters that
like junipers, i think we can assume it was from the trees overhead.
I've got it out in the light, done my usual cleanup, cut off all the
brown parts and twiggy growth, repotted it in my evergreen mix with
just a little root picking and some 'transplant starter' food. I'm
told the mold should die and flake off as soon as there's no more food
for it. What do you think ?

I don't know. If the bark is rough it will take a long time. The
tooth brush works and you should change them every three months anyway.

Hi Allen,
The "Black Stuff" is more then likely some type of Mould.
Moulds being Fungi, they need 3 conditions in order to live, feed and
multiply. These are 1. a host to live on, 2.a food source and 3.favourable
conditions in regards to temperature and moisture. Take one of these
factors away and the fungi will not be able to live.

In your case, their could be more then one reason for this mould.
The fungus could have developped on the Jun. in the landscape place. Having
the tree now at your place there is chance that the mould will simply
disappear because the favourable conditions have changed.
Quite often, moulds will develop on sugary waste products from certain
insects such as Scale, Hoppers, white fly etc.Just remember that the waste
is the host, not neccesarily your tree. So in this case you will need an
insecticide to get rid of the fungus. Makes sense?

As the good old tooth brush gives instant visual result it is also a good
tool to spread fungi to other parts of the tree or other plants.

I have found that the early signs of most fungi can be killed by exposure
to UV rays. UV is not for sale in a can from the shop, but comes very cheap
everyday from that lovely big bright sun. Put the tree in full sun for 30
minutes and keep an eye on the fungus. You might have to repeat this for a
few days. Works great on Powdery mildew (Oaks can be succeptible to this)

However, heavy infestations might need to be cleaned up with a fungicide.

Hope this is of help

Mart

THanks Mart ! Great info ... i fully agree with you, so you must be
right !
I've been removing the mildew with pressurized water. I support the
branch with my hand so it's not whipped around, but the black is
coming right off after the plant has been in mostly full sun for 6
days. The red dots i saw, i originally thought were mites, but
they're not moving ! I took a couple of cut off branches and put them
in a jar, then examined them and they look like rust or something !
There's not much of it left, i've pretty much amputated the branches
that had it. What do you think ?

When this thread started, I thought the "mold" sounded like sooty mold. Sooty mold does grow on "honeydew" from aphids or scale insects. It is harmless, except when it's thick enough to coat leaves and thereby reduce photosynthesis. Generally it is easy
to wash off, and getting rid of the insect problem gets rid of the fungus problem.

Of course, this could also be a slime mold: sometimes slime molds will climb up small shrubs and fruit on the branches. Also harmless, also easy to wash off.

Hi allen, looks you are on the right track. The red residue are probably
the dead remains of the fungi. Be interesting to hear at some stage if you
have eliminated it completely and hopefully you won't get re-infected.

Ok, here's the update. After my first 'clean up' then giving it 4
days of dry sunny conditions, I "Pressure washed" with the "flat"
setting on my watering wand and putting my hands behind the branches
and foliage for support ... the black stuff came about 90% off quite
easily to reveal nice bright green healthy old growth. I waited a
week, then did another trimming (cut out about 50% so i've got some
idea of where the style is going) and another 'pressure wash' and it
looks great. There was no regrowth of the mold at all, and now i've
got a very hearty healthy juniper with a base about 2 inches in
diameter.
