Rabbits are cuddly, docile and also efficient manure machines. Our own bunny produces piles of droppings a day, which have turned out to be manna for our plants. Rich in nitrogen and phosphorus--just what healthy plants need!
It can be spread directly on soil as fertiliser that helps retain soil structure (what we do) , or added to your compost heap.
We also have several hamsters, and their used bedding (tissue fibres, poop and pee) are mixed in with soil. We usually have more than we can finish using, so may have supplies available for those who are interested.
We sell prepackaged bags (freshly harvested, sifted and then thoroughly sun-dried). Contact us if you're keen on rabbit pee as well, which can be diluted to make 'tea', which becomes a tonic for your plants.
