Pine needles can create acidic conditions as they decompose, which may inhibit the growth of some grass species.

What is the function of the tree trunk?

The trunk of a tree is a slight modification of the stem of a regular shrub.

As trees are larger than shrubs the trunk has to provide structural support for the leaves and branches (canopy).

Trunks are normally covered with bark which offers protection to the delicate network of xylem and phloem vessels which run just below it (in the actively growing portion of the stem); remember the centre of the trunk is in essence dead material - which provides the rigid support.

The trunk extends the reach of the tree, enabling trees to stretch their branches and leaves high into the canopies of surrounding trees - looking for light.

When do you feed flowering pear trees?

After the flowers are finished in the spring.

not true. you should feed them for as long as the have leaves and only stop when they shed them and go to sleep. BTW pear trees need lots of iron.

If you feed this tree constantly while it has leaves it will have greatly reduced blooming. You should not feed it until the flowers have finished. If you feed it continuously until the leaves fall it will have leaves much later in the year and reduce its dormant time. That would be like you taking a pep pill before going to bed.

One feeding with general fertiliser in the Spring should suffice unless there is a unusual problem.
