hey there how's it going everybody Dan
here with plant abundance calm today I'm
going to be sharing with you what you
can do if you see this on your roses so
here we are it's still early spring and
as you can see the rose bushes are
starting to reach with some beautiful
flowers but as we take a closer look
here you can see how some of these
leaves aren't looking so healthy
they're yellowing they've got spots on
them now this is one of the most common
plant diseases to affect rose bushes and
it's called black spot it's caused by
the fungus diplo Karpin rose a by the
way an added tip is you can see this
chord here this is actually a landscape
colored extension cord and I'd like to
use this as almost an invisible way to
help to train my rose bushes I also do
the same thing with my fruit trees so
move it along what you want to do when
you first start seeing this type of a
pattern emerge on your rosebush is to
remove those leaves right away you can
easily do that by plucking it downward
off of the main canes and they just come
right off and you're going to want to
make sure to remove those completely
from the landscape do not put them in a
compost pile that fungus can proliferate
and come back here after years so I'm
just going to continue to go around and
anywhere I see any yellowing or spotted
leaves I'm just going to go ahead and
pull those off it's all about getting
ahead of the game here and by removing
those leaves we're helping to stop the
proliferation of this fungus this is
also going to help in creating more
aeration throughout the bush which is
very beneficial so keep that in mind
when you do your pruning you really want
airflow to be able to circulate all
throughout the bush so taking out some
of that inward growth and opening up the
middle is going to be beneficial it's
also going to allow Sun to penetrate in
and roses love full Sun so once you've
removed all the diseased leaves make
sure to pick up any fallen leaves that
are around the rose bushes as well
because these fungus spores can actually
over winter and then reinfect your
leaves and the Canes your rosebush the
following year the next step that I'm
going to recommend to defeat this fungus
is to go ahead and spray down the bush
with a copper fungicide this is an
organic method so I recommend using
about two tablespoons per gallon and a
half of water
and just throw the top on give it a few
pumps and we're ready to rock
optionally if you're concerned about any
heavy metals like copper accumulating in
the soil and affecting the soil food web
which can happen if you're applying
these type of treatments regularly you
can simply lay down a drop cloth or a
garbage bag around the base of the plant
that's going to help to catch any of the
copper dripping off the plant from
soaking into the soil and in my opinion
if you're only going to spray a couple
times a year you can probably forego
this step now before we go any further I
just want to mention this treatment is
best used as a preventative whereas you
spray the plan just after new growth
begins to emerge in the spring and also
after heavy pruning and if you are going
to apply this treatment onto a fully
grown plant you want to make sure you
don't do it in full Sun so wait either
till later in the evening or on an
overcast day so now I'm just going to
fully spray down this rosebush making
sure I get both the top and the bottom
of all the leaves and it's really
important that you wear a face mask
while you're applying this product you
don't want to inhale any of the mists
that may come your way and you really
want to spray down the whole plant very
well until you see it dripping off of
all the branches and leaves next I'm
going to recommend that you get your
roses on a regular fertilization
schedule here I've got some organic
granular fertilizer when it comes to
rosebush fertilizer I pretty much buy
whatever's on sale as long as it's
organic I also really like applying
liquid fertilizer especially this fish
emulsion here I find the liquid
fertilizer to be most beneficial during
the earlier stages of growth before
blooming as a tire and nitrogen and
because the fertilizers in the liquid
form it also does a great job at getting
those nutrients to the plants straight
away whereas the granular fertilizers
are more of a slow feed so fertilizing
your roses is it only going to help the
plant to help defend itself against some
of these diseases it's also going to
help the plant to produce more healthy
flowers and that's what this is all
about right
finally I'm going to talk about the
correct way to water your roses now this
black spot fungus especially thrives in
humid weather conditions and if you're
watering all the foliage of your plant
not just at the base you're actually
helping to create the right conditions
for this type of fungus to thrive so
it's very important that when you're
watering your roses that you water
around the base and try to keep as much
of the water off of the foliage as
possible well that's it for now
