Is it true or an urban myth that coffee grounds are good for gardenias?

Many garden sites recommend putting one's coffee grounds around gardenias? If true , how often is good? If true, can coffee grounds be combined with fertiliser designed for gardenias? My gardenias are outside in planters in Melbourne, VIC
Thank you in advance.

Answer: Hi Jacqueline,
Coffee grounds can be added to compost where they are quickly broken down and produce a lovely compost. I think this would be preferable to adding them straight onto the garden soil where they will take longer to break down. Also if they are not incorporated they may become mouldy.

Gardenias like a more acidic soil so use a suitable fertiliser such as Dynamic Lifter for camellias, azaleas & rhododendrons. Occasionally you may need to add Epsom salts if the leaves show symptoms of magnesium deficiency.
