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 snapdragons 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 snapdragons
Use the calendar to plan ahead, then check the conditions in your own garden.
- Frost tolerance does not make saturated or frozen soil suitable for planting. Wait until the bed can be worked without smearing or compacting it.
- 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.
Choose stem height and grow snapdragons in a suitable cool season
Use a bright position with rich, moist but drained soil. Avoid prolonged overhead watering and give tall plants support in exposed sites. Hot weather and drying can shorten the display, so plan the season accordingly.
Remove spent flower spikes where further branching and buds are desired, and inspect leaves for rust or other disease. Record the quality of usable stems and the timing of decline to improve next year's sowing choice.
What to record this season
Which planting period produced strong flower spikes before heat or rust reduced quality? Add the cultivar, sowing date and conditions to your growing record so you can compare next season.

Why these dates
Use a bright position with rich, moist but drained soil. Avoid prolonged overhead watering and give tall plants support in exposed sites. Hot weather and drying can shorten the display, so plan the season accordingly.
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. Snapdragons are timed from 10 weeks before that frost for an indoor start, with planting out 2 weeks before it, and this page simply resolves those offsets against the frost date computed for Delhi.
Delhi is zone 10b, within the crop's general range. This is an initial cold-hardiness check; cultivar, exposure, drainage and unusual winters can still change the outcome.

Can I grow snapdragons in Delhi?
The calendar estimates a planting window, not a guarantee of success. 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.
When should I plant snapdragons in Delhi?
Aim for 23 Dec - 21 Jan in an average year. If you would rather not gamble on the weather, wait until 24 Dec - 21 Jan - by then frost has finished in nine years out of ten.
When might snapdragons flower in Delhi?
The estimated period is 24 Mar - 23 Apr, based on 90 to 120 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 snapdragons 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.
