Although not particularly green-fingered, I am interested in growing tropical plants and have grown several bananas from seed - this year being the first that I've managed to keep one alive throughout the winter.
It has just started growing again ( 5 1/2" 140mm in the past week) so thought I would give some coffee beans a try. I selected the freshest/plumpest looking beans in stock and soaked a handfull of them overnight in a jam jar of water.
At lunchtime the next day, about a dozen of the beans had grown a little sprout so I planted these in a compost filled flower pot and put them on the window sill next to the banana.
Will they grow? Time will tell...
