Dug around in my raised beds from last year, they're loaded with these worms! Wooooo! About to empty my current bin into the new raised bed in the greenhouse and start a new bin!
@pop22 I have a question for you , would something like this be ok to use .
5IN1TM Organic Plant Food is a brilliant organic plant food containing Cow, Fowl and Sheep Manures, Mushroom Compost, Zeolite, Blood & Bone, hoof and horn plus added Trace Elements and Minerals. Mix one part 5IN1TM Organic Plant Food to three parts existing soil to enrich the soil and provide long term organic nutrients to plants. Flowers and vegetables respond extremely well to this product.
It is granulated but I am thinking about putting it in a coffee grinder to turn it into a powder form to feed the worms .
There's a saying: " garbage in = garbage out." Well, in the gardening world, garbage in = compost out!
and what goes into your compost makes a difference in the quality of the end product. worm castings are no different. What goes into the bin affects the nutrient content of the castings. the worms create nothing, they just process whats given to them into a form that is using to other micro life and plants.
If the food they get is low value, lacking in certain minerals, etc, its no better when the process is complete. And most people running small worm bins get wrong: They don't feed them EVERYTHING!
If bacteria can break it down, it belongs in your bin! meat, dairy, you name it, you can give to your worms. The key is to add these thing in small amounts. Milk and meat in particular break down much faster than plant matter. "spoiled" milk is perfect for your bin! a cup of it in a 15-20 gallon bin every 10 days or so works fine. A few scraps of meat, a few ounces every couple weeks, adds valuable nutrients to the mix.
But even if you don't want to use these things in your worm bins, here's a great way to produce worm castings superior to any you could buy. Add dry, organic nutrients to the bin! Grow More, Jobe's, doctor Earth, etc any brand will do. NPK ratios don't matter at all. A pound of dry nutes added at the rate of a cup every 10 days to a well populated worm bin will produce castings that will put any store bought nutrient to shame!
people also add sand, etc for "grit' to aid the digestive process of the worms. Well lets use useful grit!
The "father of fertilizer", Justus von Liebig, developed the "Law of the Minimum" which is important in understanding what micro nutrients do. The Law states that plant growth is determined by the scarcest "limiting" nutrient; if even one of the many required nutrients is deficient, the plant will not grow and produce at its optimum. Conventional fertilizer programs focus on the macro nutrients like Nitrogen (N), Phosphorus (P) and Potassium (K). However, if one of the many essential trace elements is deficient in the soil, the plant will not perform at its optimum, affecting yield and immune function.
So we can add Azomite and or similar sources of micro nutrients to our worm castings. Greensand also. and doing so creates a unique situation, these micro nutrients become available much more quickly! Most people don't realize that adding rock phosphate, azomite, greensand ( and my favorite bullshit " nutrient additive ) glacial rock dust. Glacial rock dust will take about 100 year to begin to be available....... and all the others mentioned aren't a lot better. 1-5 years for azomite and greensand.
But when processed thru a worm bin a usable amount of micro nutrients are made available because of the intensely active microlife in the bins!
I've just started adding these items to my bins. in about 90 days I'll be testing a soil mix composed of nothing but a base organic soil and these worm castings. I'll also mix a batch with just recycled soil and do a side by side comparison.
@pop22 have you every fed neem cake or meal? I have been throwing in a cup every so often for a year and the baby worms have multiplied like crazy. I was making a neem meal tea for fungus gnats (also recommend) and threw the leftovers in the worm bin. THE WORMS LOVE IT !! Then I did some reading and found out that many online have seen increased worm population and breading(more baby worms and cocoons). I usually have two 15 gallon smart pots full of manure going with worms.
Something else I have recently added to my smart pot worm bin is a Blumat. I would always forget to water my worms until it was too late and their population would dwindle significantly.
What do you recommend for a mineral addition to the worm bin? I currently use a mix of Azomite and basalt but do not add them to the bin. I also add copious amounts of kelp meal because I get it through a friend who buys bulk from Acadian Seaplant in Canada (I pay $1 a pound!). Do you think the minerals in the kelp would cover this?
Great tips! Especially the Blumats. I use neem cake but never though to put it in the worm bin!
I add Azomite mixed into whatever I'm feeding, you don't need much. Glacial dust, etc, is a waste of time, it take 100+ years to break down to a useable form.
