This document discusses growing fruit trees in urban spaces and provides guidance on training trees into a tall spindle shape to control their size. It notes that untreated fruit trees can grow too tall for easy harvesting and maintenance. The tall spindle technique uses dwarfing rootstocks, branch bending, and pruning the leader to control tree height while maximizing fruit production. Branches are bent horizontally and the largest ones removed annually to encourage fruiting and prevent the tree from becoming too large for its space.

- 1. Small trees, big flavor: fruit tree growing in cities and back yards Presented by: Samuel A. Bishop II Education Director, Trees New York
- 3. The fence in the background is about 6 feet tall, and this cherry tree is around 15 feet tall. Problems: Trees hard to work on without a ladder Trees hard to harvest without a ladder Trees cropping poorly when not pruned Trees outgrowing space Trees shading other crops in garden/space
- 4. This peach is tall enough that any meaningful work required use of a ladder or pole pruner/saw. More difficult and dangerous for the gardeners, and a source of potential liability. Bad Sam! PPE fail!
- 5. The same peach before pruning….
- 6. …and after. The tree had a OK open vase shape, but pruning had been neglected. Next year? Get out the ladder again.

- 9. Tall spindle concept: 1. The trunk is the permanent scaffold on which we grow fruiting branches 2. We use dwarfing rootstocks and root competition to help control plant size. Trees must be supported. 3. Branches are bent to horizontal or below to encourage fruiting and reduce vegetative growth. 4. We remove and replace the branches when they get too big. “Big branches make big trees”-Dr. Terrance Robinson 5. Control height by cutting the leader back to a side branch.

- 13. http://www.omafra.gov.on.ca/neworchard/english/apples/12trainyr3.html Once the tree gets to the desired height, keep it there by pruning back to a branch AFTER the crop or bending has bent the leader down.

- 15. Image from: http://www.omafra.gov.on.ca/neworchard/english/apples/12trainyr3.html Remove the 2-3 largest and any upright growing branches with a “bevel” cut, leaving the longer side on the bottom to make bending the new branch easier and discourage vertical growth.
- 16. Pear! (famous for getting very tall) Tree grown unintentionally as a somewhat tall spindle. Note branch bending, pruning the leader to control height. The tree had lots of fruit buds on it.
- 17. Close up of the leader, pruned at least 3 times to control height.
- 19. The principals of tall spindle • Start with dwarfing rootstock (Bud 9 or similar size), you will need to stake! • Plant close! 3 feet between trees. • When you plant, tie all feathers to below horozontal. • To control tree height, cut back top to a side branch. • Pruning yearly: remove the 2 or 3 largest branches (over ¾” thick). • Pruning yearly: “columnarize” branches – remove vegetative side branches, leave fruit spurs.
