Seasonal context
Rainfall and the growing season in New 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 stonecrops for New 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 stonecrops
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.
- Check mature size, drainage and cultivar suitability before choosing a permanent position. A suitable planting window does not guarantee long-term survival or fruiting.
Prevent stonecrop flopping by checking sun and soil
Avoid persistently wet soil and excessive fertility, which can encourage weak growth or root problems. Water a new plant while roots establish, then judge watering from the soil and plant condition rather than a fixed daily schedule.
Early pinching can make stems shorter and more branched, but it can also shift flowering time. Trial it on part of a clump before treating every stem. Leave selected seed heads for structure if desired and divide or propagate healthy material when renewing the planting.
What to record this season
Did extra feeding, shade or early pinching change stem strength and flowering time? Add the cultivar, sowing date and conditions to your growing record so you can compare next season.

Why these dates
Avoid persistently wet soil and excessive fertility, which can encourage weak growth or root problems. Water a new plant while roots establish, then judge watering from the soil and plant condition rather than a fixed daily schedule.
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. Stonecrops are timed with planting out 2 weeks after it, and this page simply resolves those offsets against the frost date computed for New Delhi.
New 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.
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 flowers reliably.

Can I grow stonecrops in New 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 stonecrops in New Delhi?
Aim for 21 Jan - 18 Feb in an average year. If you would rather not gamble on the weather, wait until 21 Jan - 18 Feb - by then frost has finished in nine years out of ten.
When might stonecrops flower in New Delhi?
The estimated period is 1 Aug - 31 Oct, based on 120 to 150 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 stonecrops 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.
