Take the Screwdriver Test.
Not sure whether you are watering your
lawn too much or too little? Then try this.
Take an 8 inch screwdriver and push it into the
ground at various places in your lawn about an hour after
you have watered. Do
it close to and far away from your sprinkler heads.
If the screwdriver goes in easily, you are watering
enough. You may even
want to consider cutting back on your lawn irrigation a
little. If you
cannot push the screwdriver in the full length, you need to
water more or have your irrigation system adjusted.
Trees, by the way, need infrequent, deep
irrigation--enough to get water 24” down into the root zone.
(Note: since we originally wrote this, we now recommend that
you remove and replace
your lawn altogether.)

Double Pot for Summer. Set your potted plants in a second, larger pot
for summer. Then
put an insulation layer of dried moss or coarse organic
mulch between the two pots.
This will keep the inner pot cooler and protect
the plant roots from sizzling heat.
You may even be able to water the plants less
often.
And whatever you do, don't plant in metal pots or cans.
They heat up and cook plant roots. |

Love the idea of a
fountain but don’t want to get involved with dreaded
plumbing and wiring?
Then consider creating a
Pampas grass (Cortaderia
selloana) “fountain” in your garden.

Waterless Garden
Fountain.
Here is how to make your Pampas grass fountain:
create a mounded garden bed where you want your “fountain”
located. It
should be at least 8 to 10 feet long by 6 to 8 feet wide by
about 1 foot high.
The center should be somewhat higher than the edges.
A raised garden
island bed would be perfect for this design.
Prepare the soil, then plant 4 or 5 Pampas grass plants on
this raised bed including one at the center.
Leave a generous space between the plants. Pampas
grass grows fast to 8 feet tall in one season and has a
graceful green arching shape – as if it is green “water”
rising up and spilling back down to the earth.
If
you don’t have the large space required for a Pampas
grass “fountain”, try doing a smaller version with
Deer grass (Muhlenbergia
rigens) or red Fountain grass (Pennisetum
setaceum). The effect with red Fountain grass
will not be quite the same, however.
Win Some, Lose Some.
A red-leafed Fringe flower (Lorapetalum
chinense) planted this spring turned crisp as soon as
the summer heat arrived.
This Fall when the weather cools down we are going to
try a Barberry (Berberis
thunbergii ‘Atropurpurea’ ) for a shrub with deep red
leaves. Barberry
cultivars come in other colors and pygmy sizes, too.
And Barberry is suitable for all desert climates.
