Seasonal context
Rainfall and the growing season in Mandoli
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 water spinach for Mandoli
- 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 water spinach
Use the calendar to plan ahead, then check the conditions in your own garden.
- Measure the soil at sowing depth. Aim for at least 20°C (68°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.
- 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.
Check planting rules and use a contained, clean growing system
Choose planting material suited to moist-soil or aquatic cultivation. Use a contained bed or vessel with a clean water supply, rather than gathering shoots from an unknown ditch or polluted pond. Plan how discarded stems will be contained.
Harvest young shoots and retain growth for recovery where using a repeated-cut system. Cultivars selected for a single whole-plant harvest may behave differently. Keep records of regrowth and do not assume vigorous spread makes every water source suitable for food production.
What to record this season
Did the contained planting regrow well without escaping into drains or nearby water? Add the cultivar, sowing date and conditions to your growing record so you can compare next season.

Why these dates
Choose planting material suited to moist-soil or aquatic cultivation. Use a contained bed or vessel with a clean water supply, rather than gathering shoots from an unknown ditch or polluted pond. Plan how discarded stems will be contained.
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. Water spinach are timed from 4 weeks before that frost for an indoor start, with planting out 2 weeks after it, and this page simply resolves those offsets against the frost date computed for Mandoli.
The calendar also applies a soil-warming estimate derived from historical air temperatures. Where that estimate is later than the frost-based date, it delays the window. Soil in your own garden can warm earlier or later; a thermometer at sowing depth is a better final check. Cold, wet conditions can slow germination and increase decay risk.

When should I plant water spinach in Mandoli?
Aim for 20 Feb - 13 Mar in an average year. If you would rather not gamble on the weather, wait until 19 Feb - 12 Mar - by then frost has finished in nine years out of ten.
Can I plant water spinach earlier in Mandoli?
The historical frost estimate is 21 Jan. For Water spinach, an air-temperature model estimates soil warmth of about 20°C (68°F) around 20 Feb. This is not a soil measurement or a forecast. Check your bed at sowing depth; cold, wet conditions can slow growth and increase decay risk.
When might water spinach be ready to harvest in Mandoli?
The estimated period is 1 Jun - 31 Oct, based on 45 to 60 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 water spinach 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.
