There are a number of possible causes.
* stress on the tree. Most commonly this is caused by over or under watering.
* over-fertilizing with nitrogen during fruit set and early development.
* lack of another avocado tree nearby. It is possible in some circumstances for avocados to be self-pollinating, but a cross-pollinator improves the percentage of fruit retained on the tree.
Because the tree can't hang on to the apples for ever..
Gravity makes an apple drop off a tree
Yes, apples fall from apple trees. Of course, they are often picked before they fall.
If the tree is fully grown you will get Apples from it during Fall.
Gravity.
go left 2 screen and continue left until the apple tree at the end. shake the tree and the apples will fall.
For the whole time the apple is in existence.
To get apples you have to buy some apple tree seeds in Vesta's shop. They can only grow in the fall. Hope I've helped!
apples can fall off trees at any time at all it happens when it is ripe
Some plants will but most don't. ( like an apple tree makes apples then they fall but the tree doesn't die. )
He watched lots of apples fall from lots of apple tree, then he thought 'Why is this happening?' Then he discovered gravity.
The fruit contains seeds, and by allowing the apples to fall when they reach maturity, the seeds can be transported a considerable distance away while remaining protected and surrounded by a source of nutrients. This enables the tree to continue its genetic lineage.
