Hi Narda and Paula,
don't have any experience with either, so I can only pass on what I've heard.
the water-absorbing crystals --- Using them in pots can cause problems if more
than a small amount are used. What happens is they swell the soil mix when wet,
but contract it when dry. When it contracts, it separates from the sides of the
pot and when you try to re-wet it, the water runs down the sides and out. This
leaves you with a pot that is very difficult to moisten again.
Regarding ZeroTol/ hydrogen peroxide --- Most of what I've been hearing
indicates it should be used frequently, maybe every two weeks or so, where there
is a problem. It is highly active when applied, killing a variety of problem
organisms, but doesn't last very long and has little or no residual effect. On
the positive side it is harmless to higher organisms, so is very safe to use.
The label does not recommend combining it with other chemicals.
I have information for
you...based on my experience.
1/4 cup...is too much unless you really
incorporate it into the soil around more than I did.
I am going with half
of that and going to stir it up into the dirt better.
The plants I put it
under...were almost pushed out of the ground.
Maybe on an established
huge plant that 1/4 cup might be good.
But try and imagine...lifting every
plant you have..and putting it underneath.
I have got to find a better way
for the older plants.
So far I am just using it in new beds with the
I may randomly pick some older hostas I don't think are
doing as well and try them.
Where you got Zerotol..might be the place
to get the Crystals. That is where I got my Zerotal.
Oh the subject of
Zerotal. Is it better to use it in the spring before hosta leaf out or after?
Will Zerotal hurt the leaves?
