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.
Plant the shrub
21 Jan - 18 Feb
After the last frost, once the soil has warmed. This crop is never fully dormant, so it cannot be planted bare-root in winter.

Seasonal context
Rainfall and the growing season in Najafgarh
July has the highest average precipitation (179 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 kumquats for Najafgarh
- July is the wettest month in the rainfall grid, averaging about 179 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 kumquats
Use the calendar to plan ahead, then check the conditions in your own garden.
- 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.
- Check mature size, drainage and cultivar suitability before choosing a permanent position. A suitable planting window does not guarantee long-term survival or fruiting.
Choose a kumquat for the whole-fruit harvest you want
Give it sun and a drained root zone. A pot can be useful where winter shelter is needed, but relative cold tolerance does not mean tender new growth or fruit can safely withstand every freeze.
Keep the root ball from becoming waterlogged or completely dry and inspect a container before moving it indoors. Compare the peel and flesh at different stages of maturity. Record the cultivar and harvest condition instead of relying on colour alone.
What to record this season
At which stage did the peel and flesh give the flavour balance you preferred? Add the cultivar, sowing date and conditions to your growing record so you can compare next season.

Why these dates
Give it sun and a drained root zone. A pot can be useful where winter shelter is needed, but relative cold tolerance does not mean tender new growth or fruit can safely withstand every freeze.
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.
Kumquats are planted once and then left in place, so there is no sowing offset to resolve. Nor is there a dormant season to plant into: this crop keeps its leaves and keeps growing through the winter, which is exactly why cold damages it. The window on this page therefore waits until the last frost in Najafgarh has passed and the soil has begun to warm, giving the roots the longest possible run before the cold returns.
Najafgarh 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.
The general establishment guide is around year 2, under suitable conditions. This is not a prediction for this location; cultivar, winter conditions and care determine whether it crops reliably.

When might kumquats be ready to harvest in Najafgarh?
The estimated period is 1 Dec - 31 Mar, based on 180 to 240 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 kumquats 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.
