This characteristic is only relevant to Apples and Pears.
Most Apples and Pears bear their fruit on tiny short stub-like branches called spurs, but a small number bear fruit at the ends of their branches alongside the leaves.
Unlike spur-bearers, which need maintenance pruning as the tree gets older, tip-bearers generally should not be pruned, as doing so would prevent them fruiting.
Tip bearers are also not suited to espalier-training or cordon-training, since these forms need pruning. Try fan-training instead.
Conversely tip-bearers are a good choice if you don't want to do any pruning.
