Last year ended with December having 34% less rain than usual and the first month of 2025 mirrored that exactly with 34% less rainfall across the region in January. This was particularly the case in South Taranaki with the monitoring station at Kaupokonui at Glenn Rd recording 59% less than usual. The district also saw the highest soil temperature with 28.1°C at Waitōtara at Rimunui Station on 22 January. Mean river flows for January were 40.1% lower than typical values, low flows were 11.6%
rainfall sites recorded figures well above their
averages for the three winter months. Our site
at Patea recorded rainfall figures that were 167%
above its average amount for those months, yet
it was still the driest of our 27 rainfall monitoring
sites around the region. Perhaps you could spare
a thought for the people working in the Dawson
Falls area, as a staggering 2,723mls of rain fell at
that site over the winter period.
Congratulations to the 55 schools, 51 early

As the soil temperature drops and the rain falls, we eagerly embark on our year-long, much-anticipated winter projects. Winter is a season of opportunities at Hollard Garden. It’s the perfect time to relocate shrubs and trees to better locations, divide Hostas, Heliniums, Rudbeckias and other herbaceous perennials and finally allow potted plants to spread their roots into the subsoil.
