Seasonal context
Rainfall and the growing season in Delhi
July has the highest average precipitation (217 mm); November 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.

Local growing check
Before choosing nasturtiums for Delhi
- July is the wettest month in the rainfall grid, averaging about 217 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 nasturtiums
Use the calendar to plan ahead, then check the conditions in your own garden.
- Measure the soil at sowing depth. Aim for at least 12°C (53.6°F); the calendar estimates soil warmth from air temperatures and cannot measure your bed.
- Check the local overnight forecast before planting out. Delay planting or keep protection ready if frost is forecast, even after the historical last-frost date.
- 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.
Avoid feeding leaves at the expense of flowers
Use well-drained soil and sun, with some afternoon shade where summers are hot. Rich feeding can encourage leaves while reducing flowering.
Watch young growth for aphids and other sap-feeding pests. Assess the plant directly rather than assuming that a calendar-compatible month prevents pest problems.
Plants can spread through self-seeding. Remove unwanted seedlings or developing seed if keeping the planting contained is important in your garden.
Growing in a container
Dwarf forms suit pots and borders; trailing forms need room to spill over the edge or climb a support.

Why these dates
Use well-drained soil and sun, with some afternoon shade where summers are hot. Rich feeding can encourage leaves while reducing flowering.
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.
This calendar uses frost-relative offsets as a starting point. Nasturtiums are timed for direct sowing 1 weeks after it, and this page simply resolves those offsets against the frost date computed for Delhi.

Aim for 14-28 Jan in an average year. If you would rather not gamble on the weather, wait until 14-28 Jan - by then frost has finished in nine years out of ten.
When might nasturtiums flower in Delhi?
The estimated period is 5-20 Mar, based on 50 to 65 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 nasturtiums 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.
