Today’s mild weather in Dunedin offers an ideal window to tend to the newly planted brassicas. With temperatures hovering around 20.2°C and 0% chance of rain, it’s a great day for the Green Dragon and Side Sprouter broccoli varieties to continue their early establishment without the worry of excess water.
Observations
- With no rain expected today, and temperatures reaching 20.2°C, the plants will require some manual watering to support establishment.
- The expected UV index of 6.4 indicates moderate sunlight; the partial shade of the bed will help prevent scorching young leaves.
- Winds are relatively gentle at 8.4 kph today, posing no significant risk of physical damage to the plants.
Actions for Today
- Ensure all plants are watered today to compensate for the lack of rain and facilitate growth in the warm, dry conditions.
- Inspect leaf undersides for yellow clusters of cabbage white butterfly eggs, especially on the cauliflowers at the sunnier north edge.
- Consider applying fine mesh netting to protect the crops from pests, especially as temperatures will peak at 27.5°C tomorrow, potentially increasing pest activity.
Looking Ahead
Expect potential rain on 2026-03-08 with 5.4mm predicted, which will alleviate the need for extensive watering in the days that follow. The increased wind speeds also warrant monitoring to ensure all plants remain supported.
The calm day and warm forecast tomorrow are reminding us that autumn in Dunedin has its gentle charms. As they say, nothing like a good day of sun before the mushrooms start thinking it’s their turn in the spotlight!

Today, a warm spell with a maximum temperature of 20.2°C combined with clear skies will promote growth in your brassicas, especially the side sprouter broccoli. While no rain is expected until next week, keep a vigilant eye out for aphids as temperatures begin to cool, which could be detrimental to your plants’ health.
Observations
- A high of 20.2°C will encourage robust growth in your Green Dragon and Purple broccoli, which thrive in mild weather.
- With no rain forecast today, moisture levels in the soil should be stable; however, monitor the soil moisture to avoid stress on your cabbage and cauliflower.
- The light wind speed of 8.4 kph today is manageable, but keep an eye on wind gusts expected later in the week, which may affect young plants’ stability.
- The absence of rain for the next few days minimizes the risk of disease, crucial for maintaining the health of your brassicas especially as cauliflower heads start to form.
Actions for Today
- Check for any aphid infestations on the growing tips of your brassicas, especially the cauliflower since they can affect young curds.
- Regularly harvest side shoots from your Side Sprouter broccoli to encourage further growth; this is a prime time to extend your harvest since growth will be enhanced by the warm weather.
- Since there is no rain forecast today, ensure the soil remains adequately moist; if the soil feels dry, consider hand watering, particularly around your cabbage plants.
Looking Ahead
Keep monitoring temperatures in the coming days, as cooling temperatures and expected wind on March 8th could stress your plants. Be vigilant for any drastic changes early next week, particularly once rain is predicted on March 8th.
The brassicas look like they’re enjoying this warm weather, but as we transition into autumn, your butterfly patrol might need to go into overdrive. Just when things seem to settle, nature throws us a curveball.
