Apple Tree Catching Nets
Dear Mr Browne
You would certainly need a strong heavy duty netting to catch the fruit from your tree.
The only suggestion I can think of for the supporting structure would be to create a hexagonal shape using posts driven into the ground at intervals around the tree, The netting could then be attached to this by nailing it to the top of the posts. Using pressure treated posts should hopefully also make the structure more pleasing to look at.
I would also recommend an apple picker to pick the fruit off the tree before it falls. Fruit picked rather than fallen will last longer in storage and be of better quality.
I hope this is helpful. Please let me know if I can be of any further help.
