I have root rotting in my apple trees, I want to ask what ratio of water and hydrogen peroxide is needed to prevent root rotting?

Question

and what concentration of hydrogen peroxide should be used (3% or 35%) along with water?? Root Rotting

Answer 1

I don't recommend it for preventing it, so much as I do correcting it. If you want rates for prevention, I would go with 1/8 peroxide to 7/8 water once per month. That should be sufficient without burning the plant.

Use only 3%, as 35% is very hard to get down to manageable levels in the amounts that you will need.

For treating it, you will use this 1 time at 1/4 peroxide and 3/4 water. Water in once, then once again after the soil dries completely or roughly a week later.

You can also use a combination of DOLOMITIC LIME and WETTABLE SULFUR once or twice per year to prevent and treat infections, and provide trace, and micronutrients to the soil.
