Hi Everyone, I have heard about adding coffee grinds to my gardenia tree? But, how much?

I've only had the tree for 2 wks. It's potted inside in a container and it gets about 5 hours of indirect sunlite. I think I'm in zone 3 or 4 in Ontario, Canada. My tree is beautiful and has many buds, but the leaves closest to the inner core of the tree have been turning yellow for a few days. I've removed at least 20 leaves so far. I'm hoping the coffee grinds may be the answer. help?????

perhaps you are over watering. that is one reason leaves yellow.i wouldn't just use coffee grounds,perhaps add a little compost.also look under the leaves for aphids ..........tom
Reply:A handful of grinds mixed in will help aerate the soil.
Reply:Well Coffee Grinds will make the soil more acidic. Gardenia plants require a Ph balance between 5 to 6.5. You can buy a PH tester at many stores like Wal-mart, nurseries etc. I bought mine at Rite-Aid for 7 dollars ( U.S. currency).


When ever you make coffee you can save the coffee grinds and add around the plant, about 4-9 inches away from the stem. do not cover the stem with coffee grinds or any fertilizer or mulch because you don't want to burn the stem.





Now you mention Leaves turning yellow. Gardenias like moist soil, but not saturated. make sure you don't water it too much. a way to tell is if you squeeze the potting soil and if water drips out, it is too moist. if you squeeze it and it is moist but does not drip, you're good to go.


Also do not add too much coffee grinds, i would suggest no more than once every 1-3 weeks with used coffee grinds from one pot of coffee.





sometimes if the leaves in the middle of the plant do not get enough sunlight they may turn yellow because they are not getting a chance to photosynthesize. any of these could be the reason(s). I hope I helped :D
Reply:really not too much. only a small sprinkle and water them in. add new coffee grinds monthly.if that doesnt wok then buy a acitic fetilizer, or gardenia fertilizer.
