What problems come up with watering in Portland?
Portland summers are mild compared with many places, but dry spells in July and August are common and shallow, stony soil dries out quickly. New lawns and new plantings need steady water in their first season. Salt spray near the coast can also stress plants, and heads should not spray salty water directly onto them.
Common problems include:
- Freezing. Water left in pipes can crack them when it freezes, so every system needs draining in fall.
- Ledge and stones. Trenching through rock slows the job and can change pipe routes.
- Overwatering. Soggy lawns grow moss and disease, and clay holds water.
- Uneven coverage. Sun, shade, slopes and wind change what each area needs.
- Water source. Public water and private wells have different pressure and flow.
A good design allows for these before anything is installed.
