I feel silly asking this, but I need to make compost for my garden, Our family does not have enough plant waste after juicing, puuring and eating, nor do we have animals (besides the dog and cat) to help make fertilizer or compost. I water my plants with the grey water after I steam my veggies for dinner to give back to the plant what I took, but so far that is it. I have not seen them suffering, but I know they need more. How can I make them some food??
