They grow in spiky shells because of defence matters. Animals will eat conkers, animals such as squirrels, badgers ect. WARNING! do not pick up conkers as they can poke into your skin and may cause bleeding!
conkers are a fruit. they have fruit inside so they will get mushy on the inside if they are growing in the summer and squirrels will also eat them however they cant grow in the winter either because it would be cold and the inside wouldn't be able to grow properly, that's why they grow in the autumn only.
1) collect a conker2) Place some crocks at the base of a pot then neatly fill it with soil, mixed with compost3)Plant the conker 2cm deep then cover it up with soil and compost4) water it well5) Put the pot in a shady place in the garden for winterAdviceYou will need to wait until the spring to see the conker tree has sprouted.You can grow the tree in a pot as long as you keep repotting it into a bigger pot whenever it gets too cramped. It is worth planting up several conkers in case some don't work.
Conkers come from the horse chestnut.
