What Is The Best Location For A Compost Bin In
Your Yard – Sun or Shade?

90. Sheet Composting Top-dressing on
the soil surface like a garden lasagna
right onto a future growing space.
Trench Composting - composting
directly in the soil
Cold Bin Composting Fill your
compost bin halfway with browns and
bury kitchen scraps
Bokashi Bucket anaerobic bacteria
(grass-like inoculated bran, rice, dried
leaves sprinkled over scraps). 10
days to ferment & “pickle” waste,
forming an acidic organic matter that
must be dug into the soil or added to
a compost pile.
TYPES OF COMPOSTING

125. The free compost bins have
trapdoors at the bottom to access
the compost which may need to be
further cured/finished at a lower
temperature.

126. Check for moisture when
turning the compost.
The consistency should
feel like a wrung-out sponge.

128. Unfinished compost
may stress plants, causing
yellowing or stalling growth

129. Heat cooks most weeds.
For hot composting turn when pile
temperature drops below 100°F or
if the pile is more than 150°F

in a Compost Pile

132. NOW LET’S TALK ABOUT…

133. Vermi-Composting Definitions
• Vermiculture – Work farming process of
culturing worms to decompose organic food
waste, turning it into nutrient rich material
• Casting – Worm waste, digested food
• Omnivores – Animals that eat plants and
animals
• Hermaphrodites – Animals with male and
female sex organs.

134. Red Wigglers

135. Contains
• 5Xs the available nitrogen
• 7Xs the available potash
• 50% more calcium
than 6” of good top soil
• Water soluble nutrient immediately available for
plant intake.
