Today in Dunedin, the Brassica Bed will encounter mild temperatures, reaching up to 13.1°C, providing a gentle relief from the recent warmth. With no rain forecasted, the Green Dragon and Purple broccoli might need a little extra care to ensure they stay hydrated.
Observations
- With temperatures reaching only 13.1°C today and no rain expected, the soil may begin to dry out, impacting the moisture needs of the cabbages and broccoli.
- The moderate wind at 15.8 kph may increase transpiration in plants, which could lead to quicker drying of soil around your Side Sprouter broccoli.
- The UV index is at 6.5; while not extremely high, it’s significant enough to cause some stress to plants if soil moisture is inadequate.
- If the forecasted conditions persist, especially with little rain, consider the vulnerability of the Cheddar cauliflower to potential heat stress given it’s positioned at the sunnier north edge.
Actions for Today
- Check the soil moisture this afternoon, particularly in the Brassica Bed, and water the plants if the soil feels dry. Focus on the Side Sprouter broccoli and Cheddar cauliflower.
- Inspect the undersides of leaves for any cabbage white butterfly eggs and remove them before they have warmer weather to develop.
- Given the increase in temperature tomorrow to 16.9°C, ensure the brassicas, especially those on the sunnier side, are well-watered in the evening to support overnight plant function.
Looking Ahead
Keep an eye on the approaching warmer day on March 6th, where temperatures will spike to 27.0°C. Be prepared for rapid drying and stress on your brassicas due to heightened wind speeds and UV exposure.
It’s Dunedin, and the weather’s indecisive as always. Just when you think it’s cooling down for good, a mini heatwave pops up next week. Keep that watering can ready!

Today brings mild temperatures peaking at 13.1°C with a nightly low of 8.6°C, creating a nice environment for the brassicas. With no rain expected over the next three days, the broccoli, cauliflower, and cabbage will need regular watering to keep them thriving.
Observations
- The maximum temperature today is expected to reach 13.1°C, which is ideal for establishing root systems in the young broccoli and cauliflower.
- Wind speeds are moderate at 15.8 kph; while not too strong, they may still affect young plants slightly, so monitor for any damage.
- UV levels at 6.5 suggest there’s some sun exposure, beneficial for leaf growth, particularly for the cauliflower at the front of the bed.
- The forecast predicts no rain for the next three days; this could lead to drought stress if not addressed with appropriate watering.
Actions for Today
- Water the brassica bed thoroughly today to compensate for the upcoming dry spell. Aim for consistent moisture, especially for the cauliflowers and the side sprouter broccoli.
- Inspect the undersides of leaves on all cabbages and cauliflower for cabbage white butterfly eggs, as conditions are good for pest activity, especially with the mild weather.
- Keep an eye on aphid activity around the growing tips and potentially apply organic pest control if populations begin to rise.
Looking Ahead
Watch for an increase in temperatures and potential winds over the next few days, particularly on March 6 when it could peak at 27.0°C. Be prepared to adjust watering according to how rapidly the soil dries out.
Today feels like a brisk start to autumn, with just enough warmth to keep everything growing. It’s a good reminder to check on those butterfly eggs—nothing like a little pest drama in the garden to keep things interesting!
