| These ash trees were planted along Aliante Parkway in North Las Vegas just north of the Aliante Casino heading toward Horse Drive. When you are driving along here look at the sizes of the ash trees planted in grass vs those planted in rock. They were planted at the same time. Those in rock mulch are much smaller but all in good health. |
Q. I often enjoy your pieces in the NLV neighborhood View,
and your suggestion of replacing rock mulch with wood chips caught my
attention. I have an 18 year-old velvet ash in a small (20′ x 20′), red rock
covered front yard. Does this tree do
better with rock or wood chips around its trunk?

A. This is where my comments can sometimes be
misconstrued. What I am trying to tell people is that for the most part, plants
that originate from nondesert or nonarid climates perform best growing in wood
mulches in the landscape. They also do better with growing in soils that have
been amended at the time of planting with organic materials like compost.

Plants
like Velvet ash (aka Arizona Ash) which is native to the desert and arid
Southwest, TOLERATES desert soils and so can be grown more successfully under
rock mulch than non-desert plants. Nearly all plants perform better with a
higher organic content in the soil but desert plants, like Velvet ash, can
TOLERATE rock mulch landscapes.

This is
true of many cacti and succulents as well. You will see them perform better if we
amend the soil at the time of planting with some organic matter like compost.

In the
case of your Velvet ash, because it is native to the arid and desert Southwest,
it can tolerate rock mulches better than say Japanese privet (native to Japan)
which does not tolerate rock mulch very well at all but is frequently placed in
rock landscapes here with, over time, very little success.

maybe it gets more water because of the grass
or maybve its a combination of things.
