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 oriental lilies 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 oriental lilies
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.
- Check mature size, drainage and cultivar suitability before choosing a permanent position. A suitable planting window does not guarantee long-term survival or fruiting.
Plan for fragrant later lilies and enough root space
Provide suitable light above and a cool, moist but drained root zone. Use a deep enough container or prepared bed for the cultivar and support tall stems before they lean. Avoid bulbs sitting in persistently wet soil.
Retain healthy foliage after flowering and remove spent blooms if seed is not wanted. True lilies are highly toxic to cats, including pollen and cut arrangements; use an alternative where contact is possible. Record cultivar performance rather than generalising from all lilies.
What to record this season
Did the flowering season, fragrance and stem height suit the planned position? Add the cultivar, sowing date and conditions to your growing record so you can compare next season.

Why these dates
Provide suitable light above and a cool, moist but drained root zone. Use a deep enough container or prepared bed for the cultivar and support tall stems before they lean. Avoid bulbs sitting in persistently wet soil.
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.
Oriental lilies are planted once and then left in place, so there is no sowing offset to resolve. What matters in Delhi is the shape of the year: this crop is dormant through the winter and is planted while it sleeps, any time between leaf fall in autumn and the restart of growth in spring, so long as the ground is neither frozen nor waterlogged. That is why the window below spans the cold months rather than sitting in the middle of the growing season.
Delhi sits in zone 10b, 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.
