Rain is set to drench the garden today, with 6.4mm expected to fall, which will be the bulk of the week’s significant precipitation. Temperatures dip to 13.1°C max, creating the perfect conditions for both broccoli varieties—Green Dragon and Purple—to flourish in the partial shade of the Dunedin autumn. Wind, however, at 40.0 kph, might give the leafy brassicas a bit of a tussle.
Observations
- Today’s 6.4mm rain will ease watering duties for all brassicas; no need to supplement moisture.
- High winds at 40.0 kph can potentially damage tender foliage, specifically the cabbage heads like Lion Heart; might be worth checking for any leaf damage post-storm.
- With 17.8MJ/m² of radiation, the South-facing Broccoli and Cauliflower should receive adequate energy despite the partial shade.
- Temperatures dropping to 9.3°C might slow pest activity, but continue monitoring for aphids, especially as the cauliflowers at the sunnier northern edge warm up.
- UV index at 6.4 today encourages leaf growth but also signals potential for sunscald on exposed curds, especially cauliflower varieties like Cheddar and Violet; shelter might be needed.
Actions for Today
- Secure netting or protective covers today to shield brassicas from high winds to prevent damage, especially for more exposed varieties at the edges of the bed.
- Hold off on any additional watering given today’s substantial rain forecast.
- Inspect leaves for cabbage white butterfly eggs post-rain, focusing on Broccoli and Cauliflower, which might serve as prime egg sites.
- Ensure cauliflower leaves are ready to blanch heads on sunnier days following today’s rain if curds are forming—this pre-emptive action prevents sun damage.
Looking Ahead
Keep an eye on the shifting wind patterns and increase in temperatures post-March 4th, as this could spur new pest activity or accelerated growth necessitating early harvesting or pruning.
The weather gods have quite the mix today—water aplenty and a blustery breath. Make sure you batten down the veggie hatches, or we might see the Brassicas take an impromptu tour of the neighborhood!

With a maximum of 13.1°C and rain of 6.4mm expected today, the cool, wet conditions will likely slow the growth of your brassicas, particularly the Green Dragon and Purple broccoli. Monitor closely for any signs of cabbage white butterfly activity, as the rain might prompt them to lay eggs in the sheltered moisture of the leaves.
Observations
- Rain of 6.4mm is predicted today, which may lead to increased humidity and a higher chance of fungal issues among your brassicas if the bed doesn’t drain well.
- Wind speeds of up to 40.0 kph could lead to some leaf damage, particularly for the more delicate cauliflower varieties, especially if they are exposed in the breezy conditions.
- Low UV levels (6.4) indicate less light for photosynthesis, which may lead to slower growth rates for the cauliflower and cabbage as they are still establishing themselves.
- A low maximum temperature of 13.1°C signals that growth rates will decline further this week, potentially impacting your timelines for side shoot harvesting of the broccoli.
Actions for Today
- Ensure to check the brassicas for any signs of cabbage white butterfly eggs, particularly after the rain, as the moisture may invite these pests.
- Given the forecasted rain, refrain from watering today, but consider appropriate drainage measures to prevent waterlogging, which could affect root health.
- Monitor for aphids at the growing tips as temperatures cool, and be ready to act quickly if any infestations are spotted.
Looking Ahead
Watch for a warming trend mid-week, with maximum temperatures reaching 21.4°C on March 5, which may invigorate growth but also increase the risk of aphid populations if conditions remain humid.
Another rainy day means I’ll be keeping a closer eye on those potential cabbage pests; those sneaky butterflies love this kind of wet weather to lay their eggs. Better to catch them early before they overpopulate!
