Guano as fertilizer

Bird droppings can be used as fertilizer, but try not to apply it directly to the soil as fertilizer, because freshly excreted bird droppings are highly alkaline and can burn plant roots, leading to poor plant growth.

Bird droppings can be used as fertilizer for growing flowers. When using, you can bury the bird droppings directly under the flower pot, or mix it with the soil and use it as base fertilizer. You can also dry the bird droppings and press them into powder. This can be used as foliar fertilizer. The fermented bird droppings can be applied to plum, oleander, and forsythia.

How to make fertilizer from bird droppings

If the bird droppings are of relatively large overall weight, you can pile them in a sunny corner, stacking them into a pyramid or derrick shape, then cover the fertilizer pile with soil and let it slowly ferment and mature. After maturation, the bird droppings should be dried, diluted, and then used as organic fertilizer.
