Why are the leaves falling from the bottom upwards on my Kiwi 'Jenny' This is the 4th year of growth and is currently 10 foot in height. I have sown in large pot in sunny location and watered. Grew very well during few good weeks but now all leaves are falling since the weather changed. Does this mean it will die as I it was a very sentimental gift and would be very disappointed to loose it at this stage. I fed with Growmore pellets a few weeks ago.
