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 December to January. There is no frost to work around, so heat is what sets the timing.

Seasonal context
Rainfall and the growing season in Mumbai
July has the highest average precipitation (834 mm); January 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 lemon balm for Mumbai
- July is the wettest month in the rainfall grid, averaging about 834 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 lemon balm
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.
- Harden off plants raised indoors: gradually expose them to outdoor light, wind and temperature before their final move into the bed.
- Check mature size, drainage and cultivar suitability before choosing a permanent position. A suitable planting window does not guarantee long-term survival or fruiting.
Control both seed and spreading roots
Grow it in sun or partial shade with drained soil. A container makes root spread easier to manage, but flower heads can still shed seed outside it. Check the surrounding ground after a season of flowering.
Pick fresh young shoots and trim tired growth to encourage a more useful leafy plant. Remove spent flower stalks before seed ripens if self-sowing is unwanted, or reserve a small flowering section for pollinators. Do not interpret vigorous spread as a reason to apply more fertiliser.
What to record this season
Was spread mainly from the original clump or from seedlings beyond it? 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. Mumbai 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 lemon balm between 10°C (50°F)50°F (10°C) and 25°C (77°F)77°F (25°C) — and in Mumbai that is December to January, 2 months of the year, taken from this location's own monthly averages. The planting window begins near the start of this period.
Mumbai 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.
The general establishment guide is around year 1, under suitable conditions. This is not a prediction for this location; cultivar, winter conditions and care determine whether it crops reliably.
