how's it going everyone so blueberries require a really low pH to grow best and
sometimes the pH can go up and it needs to be lowered so today I'm going to be
adding some sulfur to my blueberries behind me that I'm growing in root pouch
containers just to lower it so they can grow better and I noticed that the these
blueberries started putting on a bit of an iron deficiency now this can be for
one or two reasons one is that there is no iron in the soil or the second is
that the pH is too high and what happens when the pH is too high the iron becomes
locked up so the roots can't actually uptake the iron that is in the soil and
they can't use it and so what I did was have a bit of a pH test which you can
see up here and I noticed the result of that showed that the soil had a pH of
around eight to eight point five which is way way too high so I really need a
lower which is why I'm going to be adding so far however you can see that
there are some sort of green flecks in that small test so there is some parts
that are quite acidic and that was a pH of about six which is just at the top
range that pepper and blueberries prefer so that is probably the reason why
they're still just chugging along a bit okay so this brand of sulfur recommends
to add five grams per 10 liters of soil or potting mix now these root pouch
containers here they're 30 liters and this recommendation is to lower the pH
by one unit so for example from pH of 7.5 to a pH of a 6.5 but I want to lower
the pH by two units so I'm actually going to double that amount so instead
of using 15 grams per pouch I'm going to be using 30 grams per pouch which
equates to six scoops of the spoon that it includes but first I'm just going to
be taking up the mulch now I'm taking off the mulch because I
want the sulfur to break down in the soil where the roots are and not where
the mulch is now I'm just going to be adding the six scoops evenly around soil
okay now that the software's on now I'm just going to be lightly digging it into
the soil just by the cup of first few centimeters or about the first inch or
so also just make sure that you don't damage the plant roots while you do this
especially blueberries because they're quite fibrous and more to the surface
just be very careful when you're just lightly digging into the soil so there
you go guys that is how easy it is to add sulfur to your soil especially in
containers for blueberries just so they get that optimum pH range and really
explode with some growth so first these o be checking up on them about every
week and doing a pH test every week or so because sulfur actually isn't water
soluble and it requires the microbes in the soil to to break down so as the
microbes feed on it and work it it breaks down into acid and this is what
causes the pH to lower so this generally takes around two to four I think even
maybe four to six weeks to do that so I'll be coming out here every week just
doing a quick pH test just to see how it's going and if it sort of the pH then
stabilizes after a number of weeks at a pH that I think it's still too high I'll
just be adding a bit more sulfur every few weeks until it hits that four to six
pH range so that is it for the video pretty much so thank you for watching
guys if you stuck around to the end so make sure if you like that please leave
it a big thumbs up and if you have any comments suggestions or questions or you
