directly onto wounded coconut trunks.
oo much of a good thing isn’t good for you — or for
plants either. A common problem in our landscapes
is over watering. Not only does this waste money on
unnecessary water and sewer fees, it wastes one of
Hawaii’s most precious resources — fresh water. It is
also harmful to plant health, because roots need oxygen
to function properly. Anaerobic soils lead to root rot and
stressed plants, making them more susceptible to pests
and diseases.
A common factor leading to over watering is that
automatic irrigation systems are set for frequent cycles
when landscapes are newly planted. This helps plants to
establish. Unfortunately, the irrigation frequency does
not always get reduced as plants begin to grow. When
maintenance is turned over to the end user, and after a
typical 90-day establishment period, the irrigation should
be set at a schedule appropriate to the area’s climate,
topography, soil type, and the current season, and the end
user should be instructed on how to use the irrigation
system.

monitor soil moisture, there are simple, low-tech indicators
that soil moisture is too high. If you see moss or algae
