Indoors I dont. Out in the garden is fine
Theres no smell, it actually smells just like potting soil. Or maybe its because I did put some soil in there but not alot.
Even broken down powder eggshells take a while to be readily available.. Eggshells even when crushed up are still not readily available calcium.. Eggshells are calcium carbonate which takes a while to break down.. You would usually amend your beds with this and let it break down over time
So leaving them in big pieces like the op has done is better? Interesting.
I'm currently in coco and not composting anymore so I'll watch this later.
Moisture neutralizes pollen pretty quickly. I can't imagine any viable pollen being in a compost pile, regardless.
It does not matter in the end.. even very fine dust like eggshell powder will still take a while to break down.. Unless you are adding flames and intense heat to breakdown that carbonate, you will be waiting a while for it to naturally breakdown.
I find little straggle plants in my compost all the time, likely pollen and weed seeds blown around by the wind.
You are right sir, compost does take time to breakdown, you can speed this process up by turning your compost more often, allowing air to penetrate inside the compost, this will speed it up a lot, but with the eggshells there is very little that can be done to break them down faster, unless you are going to bring flames and intense heat to the equation.
