- dpark 8y agoOnly if you're dumping fresh grounds directly onto the plants. Used grounds that have been composted are generally regarded as quite beneficial.
- wayanon 8y agowhoops that's what I've been doing past few weeks...
- dpark 8y agoUsed grounds are probably fine if that's what you've been doing. Actual fresh grounds that have not been used to brew coffee are not a great idea.
- reaperducer 8y agoInteresting. My grandmother used to dump her coffee grounds on her roses almost every day. She swore it was what made them so big. A lot of Starbucks stores will give you grounds for free for use in your garden. I don't know if they recommend composting first or not. My guess is they don't care.
- dpark 8y agoUsed grounds != fresh grounds. :) Used, composted grounds are definitely good. Used grounds add biological material to the soil as well and lots of people have good success with that from what I understand.
- always_good 8y ago> One of the key functions of caffeine in the plants that produce it is allelopathy – the ability to reduce competition from surrounding species by suppressing their growth. Wow, makes sense. I never stopped to ask why the plant produced caffeine in the first place.
- pajaroide 8y agoWell, not only that; caffeine in plants acts as a natural pesticide.
- samatman 8y agoCaffeine in a warm, moist, bacteria-rich environment, has a half-life comparable to that in the human body. Compost your grounds, they're great.
- moron4hire 8y agoCoffee grounds are also very acidic, so you could be killing the microorganisms in your compost.
- samatman 8y agoCompost your egg shells also!
- tlavoie 8y agoWorks great for growing mushrooms though...
