Two magnolia questions
 

The house I moved into this spring has a beautiful magnolia tree in
the back yard but there is essentially no grass under the tree. It
was a little sunken and I filled with top soil and reseeded with a
shade mix early in the summer. The grass came in well but then died.
We had a fairly wet summer and I didn't fertilize after the starter
fertilizer so I don't think I "burned" it. I checked the pH and it's
nearly neutral. Is there something about magnolias that would keep
the grass from growing well?

Also, there's one branch that's a bit low and I'd like to prune it.
Should I do that in the fall or the spring?

Magnolia grandiflora (which is what I think of when I read the name) or one
of the other several dozen varieties?

Damifino. It has pink and white flowers.

If it lives okay in your area and also has pink and white flowers, it is
definitely NOT a M. gradiflora (southern magnolia). Instead, it's
possibly a M. soulangeana or M. stellata. In any case, it's most likely
a deciduous magnolia.

If it blooms in the spring, prune it right after it blooms. If it
blooms in the summer, prune it just as the leaf buds start to swell in
the early spring. Entire branches should be removed; a branch that is
merely headed will heal very slowly and might die.

Do not try to grow anything under it. Planting under it is not good for
the magnolia itself. It cannot take repeated disturbance of surface
roots (e.g., to plant annuals, divide bulbs and perennials, or aerate a
lawn) in its root zone. It also does not like foot traffic in its root
zone.

Yes, definitely deciduous.

Well, where's a "branch" start/end? Can I trim it at any fork or do I
have to go back to the trunk? Should I seal the end where I prune?

Unfortunately, it's in sandy soil on a slight grade and I'm getting
erosion. I can live with it not being grass (so there isn't foot
traffic mowing and aeration, etc.) but I need something there to hold
the soil. A low-lying ground cover is fine. Any recommendations?

Trim to a fork. I use white glue (Elmer's, Willhold, GluBird, etc) to
seal any pruning cuts larger than the diameter of a pencil. Do NOT use
a tar-based pruning paint, which can cause further damage.

A low-maintenance perennial or woody ground cover should be okay. It
will also discourage foot traffic. My Sunset "Western Garden Book"
specifically says not to plant a lawn in the root zone but that
magnolias do well in shrub beds.

Magnolia trees produce dense shade. Grass needs sun, the more the
better. If you must, prune it after it blooms.

Watch out for so-called tree experts who do not understand tree biology.
Storms, fires, floods, earthquakes, tornado's, volcanic eruptions and other
abiotic forces keep reminding humans that they are not the boss.

A low-maintenance perennial woody or ground cover should be no problem. It will also hinder the flow. My sunset "West Park book " clearly did not want the grass root zone of plants do a good job, but Magnolia shrub beds.
