coffee and egg shells

if i would use coffee grinds and egg shells could i just set it on top of the soil my plant is in and let it compost on top of it?? wont the sun break it down and release the nutrients into the soil? or i i have to put it into water after composted?

Coffee is real acidic, don't go too heavy

If you top dressed with these items the coffee grind might breakdown in time for your plants to benefit from them but as already mentioned, they're acidic and will probably just screw up your PH more than help. I think the egg shells will take substantially more time to break down, your plants will probably be harvested by time they break down. Probably best to actually compost the stuff and use the results next season.

Why do this? there are better nutes that will do a better job, too messy and could encourage disease/pathogens. Keep the eggs and coffee for breakfast.

Vap is right (once again!) The organic matter will probably not help at this point due to the time factor. Organics are slow release. He'd be better off composting them and using them next run. But there most definitely are no BETTER nutes out there than organics. Arguably almost as good, but certainly not BETTER. I aint wanting to start an argument over chemical vs organics, both produce fine results when done properly, but that statement was very misleading. Organics do not encourage diseases nor pathogens. They inhibit such.
I save and compost all my grounds and eggshell, in fact I get more from the local waffle house!! They make a great amendment to my soil mixes. Not everyone is able to compost, but those who can, I highly encourage you to do so.

Myth: Used coffee grounds are acidic.


Top dressing with coffee grounds will give your plant instant access to Nitrogen and a host of other elements. On average they contain about 2% Nitrogen....

http://www.ehow.com/info_7811674_coffee-added-soil-top-dressing.html Heres the entire article some of my above post was taken from. You have been told they are acidic and may contain pathogens. Both cases are incorrect. Used grounds are not acidic and contain many things that actually combat fungus and disease.

I pour left over coffee right on my plants. I get gallons of coffee grounds from a local shop and compost them. I have great compost. Egg shells do take a while to break down. Some people boil them first to break down faster, I do not. I often put fresh coffee grounds around my plants also. I though I think it would benefit better composted many people use both fresh and rave about the benefits.

i use both, i only use used coffee grounds though and mic it into the soil, ive put at least 5 gallons in my soil and the ph didnt change at all, i also used egg shells ( uncomposted) in the soil, i get them real dry 1st and then smash them into a powder they break down much faster

Spent coffee grounds are not in fact acidic, because nearly all the acid is water-soluble and remains in the brewed coffee. Therefore, the true pH of coffee grounds is typically neutral, about 6.5 to 6.8, but the pH can change over time as the coffee grounds decompose.​

from my assumption of his lack of knowledge i was assuming he was just going to bust open some new folgers and use that
