Today, Dunedin’s gardens will experience cool temperatures with a high of 16.7°C and no expected rain, creating a calm atmosphere for your brassica bed. With winds picking up significantly to 37.5 kph tomorrow and more rain expected, it’s essential to ensure your cauliflower and broccoli are adequately protected.
Observations
- The calm weather today with moderate temperatures allows for good plant inspection time, particularly checking brassicas for any pest issues.
- Moderate UV index (6.7 today) suggests plants will get some needed sunlight, though with the partial shade, impacts will vary.
- High winds tomorrow (up to 37.5 kph) may cause physical damage to tender plants or those with taller, loose foliage.
- Rain of 3.6mm is expected tomorrow, which should suffice for the watering needs of your current plantings, reducing manual watering.
Actions for Today
- Today, inspect the undersides of cabbage leaves for cabbage white butterfly eggs and consider netting if infestations are detected.
- Given the significant winds forecast for tomorrow, stake any taller brassicas, particularly the broccoli, to prevent wind damage.
- Postpone any supplemental watering today, and let tomorrow’s rain provide for the water needs of plants.
Looking Ahead
Watch for potentially damaging winds tomorrow and take steps to shield plants as needed. Following the rain and cooler temperatures, plant resilience should be monitored closely after March 1st for any signs of stress or pest incidences.
Checking for pests might feel like a chore, but catching them early saves a lot of heartbreak later. The wind’s not the real enemy here, it’s those sneaky caterpillars.

Today’s mild temperatures, with a max of 16.7°C, and forecasted rain of 0.0mm mean the Brassica bed will remain relatively dry and comfortable. As we head into the wetter conditions tomorrow, it’s crucial to keep an eye on moisture levels for the broccoli and cauliflower, especially for the White and Cheddar varieties.
Observations
- With a maximum temperature of 16.7°C today, the plants can continue their growth without the stress of heat. This is beneficial for the broccoli and cauliflower, which prefer cooler conditions.
- An absence of rain today means the soil will likely dry out, so monitoring moisture is essential, particularly for the newly planted broccoli and cauliflower.
- High wind expected at 7.3kph could disturb any loosely attached leaves; check for damage or the need for staking, especially on the larger brassicas.
- The UV index is relatively high at 6.7, which may stress young plants if they were freshly uncovered; ensure they are adequately shaded from direct sunlight, particularly the more delicate cauliflower varieties.
Actions for Today
- Check soil moisture: Since there’s no rain today, assess if the soil needs watering, especially focusing around the cauliflowers and broccoli.
- Inspect for pests: Look closely for any cabbage white butterfly eggs on the undersides of leaves, especially on the cabbage varieties, as their activity will ramp up in warmer weather.
- Prepare for tomorrow’s rain: Ensure the brassicas are secure and consider placing fine mesh netting over seedlings now, as tomorrow’s predicted wetness (3.6mm of rain) could attract pests.
Looking Ahead
Keep an eye on the weather as rain is expected within the next two days, which may lead to growth spurts but could also create conditions for pests. Also, watch for any signs of blight or disease that thrive in wetter conditions.
It’s that time of year when the plants have a mind of their own, and you can practically see them inching towards that sunshine. Just don’t let them get lazy – a bit of attention now will pay off later when you’re enjoying fresh, homegrown meals.
