Coffee powder should not be thrown in the trash after cooking. You can use it for fertilizing.

For roses, rhododendron or oleanders, the additive in the soil is also ideally suited. If you want to do something good for your houseplants, it is worth using ferns. If the garden is to remain permanently moss-free, it must be scarified at least once a year and the turf must be scratched. There are other kitchen waste that is worthwhile as a quick, free fertilizer.
