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.

The opening weeks of the stretch when the average temperature suits this crop, which here runs from June to August. There is no frost to work around, so heat is what sets the timing.

Seasonal context
Rainfall and the growing season in Kinshasa
November has the highest average precipitation (317 mm); July has the lowest (4 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 larkspurs for Kinshasa
- November is the wettest month in the rainfall grid, averaging about 317 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 larkspurs
Use the calendar to plan ahead, then check the conditions in your own garden.
- Measure the soil at sowing depth. Aim for at least 5°C (41°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.
- 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.
Grow annual larkspur for spikes rather than a permanent clump
Provide full sun and well-drained soil. The RHS describes both protected and outdoor seed raising; choose a method that fits your local season and transplant young plants carefully. Its UK sowing months are not a worldwide calendar.
For cut flowers, harvest spikes when the lowest buds have opened instead of waiting until the whole stem is at its peak. Leave selected plants to complete their display if border colour is the priority. Record the actual sowing-to-flower interval for the named strain rather than expecting an annual to return as a perennial crown.
What to record this season
When did the lowest buds open, and did the chosen strain give stems of a useful length? Add the cultivar, sowing date and conditions to your growing record so you can compare next season.

Why these dates
Frost-relative timing needs a dependable seasonal frost date. Kinshasa 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 larkspurs between 5°C (41°F)41°F (5°C) and 25°C (77°F)77°F (25°C) — and in Kinshasa that is June to August, 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 90 to 110 days from planting to flowering under suitable conditions.
Kinshasa sits in zone 13a, 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 should I plant larkspurs in Kinshasa?
The temperature-based window is 1-15 Jun. Kinshasa has no dependable frost season: June to August have monthly averages inside the model range for larkspurs. Check seasonal rainfall, heat and cultivar requirements before planting.
When might larkspurs flower in Kinshasa?
The estimated period is 30 Aug - 19 Sep, based on 90 to 110 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 larkspurs 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.
