The worm casting tea you purchased is a concentrate.
Mix one (1) part worm tea concentrate to ten (10) parts water and water plants as normal. You cannot use too much worm tea; overuse will not harm plants.
For best results use worm casting tea as often as you water your plants.
Worm tea is loaded with healthy microorganisms which are beneficial for the growth of your plants.
Worm Tea is at its highest potency immediately after brewing (when you purchased it). It is best used right away.
To prolong the worm tea potency for an extended (but not too long) period of time: Every time you water your plants (at least weekly) add a drop or two of honey or a sprinkle of sugar into the bottle, put the cap on and shake the bottle. Store in a safe dark place with the top off allowing oxygen for the microorganisms.
