WHAT IS ROOTSTOCK AND WHY DOES IT MATTER?
The rootstock onto which your tree is grafted will determine the ultimate height of the tree when it is mature. If you are planting on open ground and have lots of room then this is not so relevant but for those with smaller gardens or who wish to grow their own fruit on the patio or in pots then the information below should give you some pointers.
I WANT TO PLANT AN APPLE TREE, WHICH ROOTSTOCK SHOULD I CHOOSE?
