i was in the mall the other day when i passed by starbucks and noticed there was a bin full of coffee grounds packed nicely in aluminium foil bags. i asked the staff and was told these are given away free for use in your garden.
since we are already composting our organic waste, coffee grounds is a nice addition. furthermore after brewing, most of the acidity has been removed and tests on coffee grounds show that they register a pH of around 6.9 which is as good as neutral. they are rich in nitrogen so your plants would definitely love them. and the fact that they smell good too! oh yeah, the smell is a natural insect repellent.
just treated some coffee grounds to our plants. will see how they grow.
thanks to starbucks for this initiative. we need more of such environmental consciousness!
i just checked with starbucks malaysia, seems like most starbucks in klang valley region participate in this program but less so elsewhere. if your local starbucks aren't part of this program, talk to them. perhaps place a bin there for them to toss their coffee grounds so that you could collect it from time to time.
