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.

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 Yates Thrive Natural Roses & Flowers Pelletised Plant Food. It's enriched with Dynamic Lifter and has added nitrogen, phosphorus and potassium to give your flowering plants the right balance of nutrients for their growing needs. . Occasionally you may need to add Epsom salts if the leaves show symptoms of magnesium deficiency.
