Last Summer I planted 5 orange seeds in a pot and left them outside where they got Sun for most of the day, watering them when the soil looked dry. They seemed to take forever to germinate,but eventually I saw the first ones started to come up.
The first 2 photo's you see here are the seedlings after a couple of months.
During the early winter period the seedlings stopped growing, I am not quite sure why this was, but it may be because that is when they are with fruit when mature.
Around the middle of January I made sure that they were put onto a sunny windowsill when there was Sun and they started to spring into life again.
So the second 2 photo's you see here are showing the new growth. You can see they are about twice the size they were before. 5 months has passed between the 2 sets of photo's
So don't just throw away seed from fruit that you have eaten, pop them in some soil and see what happens :)
