Today in Dunedin, the garden is set for a cool and overcast day, with a high of just 11.3°C and gentle rain of 1.2mm expected. This weather makes it a perfect time for the Green Dragon and Purple broccoli to focus on leaf and root development without the stress of excessive sun or heat.
Observations
- With a maximum temperature of 11.3°C today, expect the brassicas to experience slow growth, which is typical as they focus on root establishment under cooler conditions.
- The modest rainfall of 1.2mm today means the soil will stay sufficiently moist, reducing the need for additional irrigation.
- Wind gusts up to 37.1kph could disturb delicate new leaves, particularly on cabbages and cauliflowers, which are less sheltered in their current positions.
- The UV index of 6.2 indicates moderate protection will be necessary if working in the sunniest spots of the garden to prevent leaf scorch on sensitive new growth.
Actions for Today
- Refrain from watering today due to the expected rainfall, which should suffice to keep the soil adequately moist.
- Check the underside of the Brassicas for cabbage white butterfly eggs, as they can still appear even in cooler weather.
- Considering today’s wind, ensure that any floating row covers or mesh netting are secured firmly to protect the cauliflowers at the front from physical damage.
Looking Ahead
Keep an eye on the temperature increase coming on March 6th, which reaches up to 24.8°C. This spike warrants monitoring for potential aphid activity, especially on the growing tips of broccoli and cabbage.
It feels like a good day to sit inside with a cup of tea, keeping an eye on the weather through the window. Always remember, a little rain today saves you a chore and gives those brassicas a nice drink from the sky.

Today, Dunedin will experience a maximum temperature of 11.3°C with light rain coming in, totaling about 1.2mm. While conditions remain chilly for the broccoli and cabbage seedlings, the rain might help with moisture retention in the soil after the recent compost application.
Observations
- The forecast indicates light rain (1.2mm) today, which should help keep the soil moist but may require monitoring for excess water pooling around the plants.
- With maximum temperatures only reaching 11.3°C, the brassicas, especially the heat-sensitive varieties like the Cheddar cauliflower, may continue to grow slowly as they adjust to cooler temperatures.
- Wind speeds of 37.1 kph could potentially damage delicate leaves of younger plants, making regular checks for any wind-borne stress advisable.
- The UV index is moderate (6.2), suggesting limited sunlight for photosynthesis, so pay attention to the spacing and shading of the plants to ensure they get enough light during this transitional season.
Actions for Today
- Check the brassicas, particularly the Cheddar cauliflower, for signs of stress due to the wind. Reinforce any loose leaves or stems if necessary.
- Monitor the soil moisture after today’s expected rain; delay any watering until later in the week when it’s expected to be drier.
- Inspect the undersides of cabbage leaves today for any signs of cabbage white butterfly eggs, especially with cool and damp conditions that might increase pest activity.
Looking Ahead
Over the next few days, keep an eye on the temperatures, which are expected to rise slightly before dropping again, as well as the potential for increased moisture from further rain. Changes in temperature can stress the plants, particularly the newly established brassicas.
With rain today, it’s a good excuse to pull out the gardening chair and survey the progress. Just hope the butterflies don’t decide to take shelter with us!
