compost time !

Spring is Finally showing itself again and I've been thinking about gardening. Because we will be starting a new garden this year at our new home, we will need to start from scratch. Pierre plowed a plot last fall and now its time to rototill all the goodies into it. We will be starting a compost bin but in the mean time we have been saving up egg shells ( crushed of course), coffee grinds and leaf piles all winter to plow in for this year. I have found a list of compostables for anyone who's wondering what's hot and what's not. Happy gardening !
AshesMaybeFrom untreated wood or paper, yes, in small amounts; but not from barbecues, plywood, coloured or glossy paper
Banana SkinsYesDecompose rapidly; can help to activate a slow compost; loaded with plant nutrients
CardboardYesShred, soak, and mix with "greens"; but try first to reuse or recycle it
Citrus FruitsYesShred rinds; bury in compost to discourage fruit flies
Coffee GroundsYesGood earthworm food; use directly on many plants; compost shredded filters, too
Corn CobsYesShred; adds both fibre and nutrients to compost; good mulch; slow to break down
Dairy ProductsNoFats seal off air from compost; odours attract pests
Diseased PlantsNoCompost heat may not destroy disease; destroy or discard to avoid spreading
DishwaterMaybeIf water doesn't contain grease or chemical cleansers, use it to wet pile
Dust and LintMaybeUse vacuum cleaner debris and lint from clothes dryer, if mostly natural fibres
EggshellsYesDry and crush first; good earthworm food; slow to break down; help neutralize acidity; as mulch, may discourage slugs
Evergreen NeedlesMaybeHighly acidic; better yet, use as mulch
FabricsMaybeSmall scraps of wool, cotton, felt and silk; not synthetic fibres or blends
FeathersYesKeep somewhat wetter than usual; extremely high in nitrogen
FishMaybeOdours and pests are problems with fresh or smoked fish, but dried fishmeal is fine
Grass ClippingsYesAvailable and valuable; mix well to avoid clumps; leave some clippings to feed lawn
HairYesBoth human and pet hair; keep quite damp; avoid using if coloured with chemicals
Hay and StrawYesVery good fibre, nutrients usually low
LeavesYesShred and soak; add both nutrients and fibre; tend to be slightly acidic
ManureYesCow, horse, pig, rabbit, poultry -- the fresher the better -- helps any compost
Meat and BonesNoOdours and pests are problems; but dried, ground bonemeal is fine source of nitrogen
SoilYesAdds decomposer soil organisms; scatter lightly through pile to avoid compacting
NutshellsMaybeCrush delicate shells like peanuts; heavier shells are better used as decorative mulch
PaperMaybeShred; not glossy/coloured which contain chemicals; better to recycle if possible
Pet WastesNoRisk of pathogens and parasites; use only barnyard manure (horse, cow, sheep, etc.)
RhubarbMaybeRaw leaves poisonous to humans; composted leaves may harm insects and other plants; stems are fine; roots may continue to grow
SawdustMaybeHardwood sawdust, yes, in very small quantities; softwoods may inhibit composting; plywood may contain chemicals
Seafood ShellsYesCrush or grind very finely; break down very slowly; reduce acidity; good mulch
SeaweedYesRinse off salt so it won't contaminate soil; great fertilizer
SodYesKnock off excess soil; pile upside down; cover to prevent rooting; compost separately to avoid compaction
SoupMaybeVegetable, yes; do not use soups with cream or meat-based broths to avoid odours and pests; read labels on canned soups.
Tea LeavesYesHigh in nitrogen; can be applied directly to some plants; compost tea bags too
ToadstoolsYesDecompose quickly; excellent source of many minerals
WeedsYesDiscard mature seeds, persistent roots, weeds treated with herbicides/pesticides
Wood ChipsYesShred if possible and soak; use big pieces as mulch first, compost when weathered
