I Have a grafted Ricks Red finger lime that I purchased about 5 years ago. I am in Melbourne. The plant is in a large pot. Plenty of green leaves and red tips to end of branches, I have tried the magnesium fertilising thing a couple of time, seems to make it flower prolifically but flowers are not showing fruit this year, and just die off. I have 1 fruit left on it from last year - it just sits there not growing, currently it is around 1.75 cm long and hanging in there where I stare at it every morning It lives mostly in sun after around 10am. It is watered every 2nd day or daily when whether is hot (over 35 degrees C) Should I shift it to a place more shaded. Or is there something really wrong
