Winter has firmly settled over South Wairarapa, and while we are currently dealing with crisp frosts and muddy boots, the big talking point among local growers is the incoming El Niño weather pattern.
Forecasters are warning that this climate cycle will bring a hot, dry, and notoriously windy spring and summer to our region. If you remember past local droughts, you know that relying solely on town supply when council restrictions hit can lead to a dry, struggling garden. This July provides a prime opportunity to future-proof our backyards by investing in rainwater harvesting systems. Catching the winter rain now and storing it in tanks is the single most effective way to secure a self-sustaining water supply for your food forest and veggie beds before the dry season arrives.
Setting up a rainwater system can be as simple or as sophisticated as your space allows. For small urban plots, positioning a couple of two-hundred-litre rain barrels beneath your shed or house downpipes provides an easy, accessible reserve for hand-watering. If you are managing a larger food forest or an expansive home orchard, investing in a larger slimline or heavy-duty plastic tanks a true game-changer. The trick is installing them this month while our roofs are still seeing regular rainfall, allowing you to enter the warmer months with maximum storage. Pairing your tanks with a basic first-flush diverter ensures that the dust and bird droppings from the roof are redirected, leaving you with clean, pure water that your plants will love far more than chlorinated tap water.
