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.

Seasonal context
Rainfall and the growing season in Matadi
March has the highest average precipitation (167 mm); July has the lowest (0 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 mint for Matadi
- March is the wettest month in the rainfall grid, averaging about 167 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 mint
Use the calendar to plan ahead, then check the conditions in your own garden.
- Measure the soil at sowing depth. Aim for at least 10°C (50°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.
- Check mature size, drainage and cultivar suitability before choosing a permanent position. A suitable planting window does not guarantee long-term survival or fruiting.
Contain spearmint before it becomes a bed-wide crop
A separate container makes the spread easier to manage. Check drainage holes and stems hanging onto nearby soil, since a pot is not a permanent escape-proof barrier. Provide moisture and sun or partial shade rather than treating mint like a dry-soil Mediterranean herb.
Pick young shoots regularly and cut back tired flowering growth for fresh leaves. Examine leaves for rust or spots and remove badly affected material. If the centre becomes crowded, divide healthy growth into fresh growing medium instead of keeping an exhausted root ball indefinitely.
What to record this season
Where did runners escape, and which position produced clean, tender leaves? 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. Matadi 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 mint between 10°C (50°F)50°F (10°C) and 25°C (77°F)77°F (25°C) , and Matadi spends the year outside that range, which is why there is a warning above rather than a date.
Growing mint in Matadi
Can I grow mint in Matadi?
The calendar estimates a planting window, not a guarantee of success. March is the wettest month in the rainfall grid, averaging about 167 mm. Check how your own bed drains and plan watering around actual soil moisture; monthly rain totals are not an irrigation schedule.
Why is there no model planting window for mint in Matadi?
The monthly means do not provide a period inside the temperature range used for this crop. The model therefore provides no outdoor window; it does not prove that every cultivar will fail. Check local growing evidence before choosing a variety or changing the growing conditions.
How much frost will mint 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.
