I am trying to make a solution to clean some new plants I have bought/will
buy.
Som einstructions on the web says to have 1 part bleach and 19 parts
water.
What does this mean?

"parts" means quantity or volume. 1 tablespoon bleach
to 19 tablespoons water, for example. Or whatever
measuring system you use.
