Each window is a planning range. Check the forecast, soil and cultivar before planting; a later date is not automatically safer in hot or wet conditions.

1-26 Dec
The opening weeks of the stretch when the average temperature suits this crop, which here runs from December to February. There is no frost to work around, so heat is what sets the timing.

Seasonal context
Rainfall and the growing season in Hub
August has the highest average precipitation (74 mm); April has the lowest (1 mm). Compare this pattern with the planting windows and your water supply.
During wetter months, check that beds and containers drain after heavy rain. During drier months, plan how you will keep seeds and new transplants watered. Monthly averages can hide long dry spells and intense storms; they do not show soil moisture, humidity or this week's weather.
Frost-free does not mean every month is suitable. In tropical and monsoon climates, rainfall, heat, drainage and the cultivar can set the practical growing season. Match the temperature window to these conditions and check advice from a local grower before buying planting material.

Local growing check
Before choosing cornflowers for Hub
- Average daytime highs reach at least 32°C in April, May, June, July, October. Plan establishment and flowering with local heat advice. This screen highlights hot months; it is not a crop-specific damage threshold or a heatwave forecast.
- August is the wettest month in the rainfall grid, averaging about 74 mm. Check how your own bed drains and plan watering around actual soil moisture; monthly rain totals are not an irrigation schedule.
The temperature and rainfall tables on this page show the underlying climate estimates. How these suitability checks work · Record what happens in your garden.
Before you plant cornflowers
Use the calendar to plan ahead, then check the conditions in your own garden.
- Measure the soil at sowing depth. Aim for at least 7°C (44.6°F); the calendar estimates soil warmth from air temperatures and cannot measure your bed.
- In a frost-free climate, check seasonal rainfall, humidity and heat before planting. A month with suitable average temperatures can still be too wet, dry or hot for this crop.
- Harden off plants raised indoors: gradually expose them to outdoor light, wind and temperature before their final move into the bed.
- Use the maturity range on your seed packet when choosing a variety. Cold, short days and transplant stress can make harvest later than the calendar estimate.
Use the cooler season and manage self-seeding
Choose full sun or light shade with drainage. Too much shade can leave stems weak and leaning, while tall varieties may need support.
Avoid unnecessary fertilising: cornflowers tolerate relatively poor soil. Maintain moderate moisture while plants establish rather than leaving a new sowing to dry out.
Deadhead to limit self-seeding, or leave some seed heads where wildlife and natural reseeding are welcome. Check local planting guidance before allowing a non-native plant to spread.

Why these dates
Frost-relative timing needs a dependable seasonal frost date. Hub has no such date in this record, so this page compares monthly temperatures with the crop's model range instead. Local wet and dry seasons, day length and cultivar requirements still need a separate check.
The model uses a growing-temperature band for cornflowers between 7°C (44.6°F)44.6°F (7°C) and 25°C (77°F)77°F (25°C) — and in Hub that is December to February, 3 months of the year, taken from this location's own monthly averages. The planting window begins near the start of this period. The catalog estimate is 65 to 85 days from planting to flowering under suitable conditions.
Hub sits in zone 12a, which is above the catalog range. Confirm the exact cultivar locally; a zone number alone cannot measure summer heat or winter chill. The calculated dates do not confirm that this crop is suitable here. Check cultivar requirements and local growing experience before planting.

When might cornflowers flower in Hub?
The estimated period is 4-24 Feb, based on 65 to 85 days from the modeled planting date. Cultivar, planting material and growing conditions can change this interval; check the plant as well as the calendar.
How much frost will cornflowers tolerate?
Check the named variety and local forecast before exposing young growth. The catalog cold-damage figure is a reference, not a guarantee: plant age, acclimatisation, wind and the duration of a freeze affect damage.
