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 pak choi for Azcapotzalco

July is the wettest month in the rainfall grid, averaging about 156 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 pak choi

Use the calendar to plan ahead, then check the conditions in your own garden.

Measure the soil at sowing depth. Aim for at least 10°C (50°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.

Separate baby-leaf harvest from full-size plants

Keep growth steady with fertile soil and reliable moisture. Check the variety's seasonal advice because unsuitable temperatures and day length can cause early flowering.

Harvest whole young plants or selected outer leaves according to your plan. Check the leaf bases for slugs and damage; a calendar date cannot tell you whether the hidden stems remain sound.

What to record this season

Was baby-leaf or full-size harvesting more successful in that season? Add the cultivar, sowing date and conditions to your growing record so you can compare next season.

Why these dates

Keep growth steady with fertile soil and reliable moisture. Check the variety's seasonal advice because unsuitable temperatures and day length can cause early flowering.

Protect tender growth from frost and wait for suitable growing warmth. The catalog cold-damage figure is a reference, not a guarantee: duration, wind, plant age and acclimatisation affect damage.

This calendar uses frost-relative offsets as a starting point. Pak choi are timed from 4 weeks before that frost for an indoor start, with planting out 1 weeks before it, and this page simply resolves those offsets against the frost date computed for Azcapotzalco.

The median frost-free season here is 281 days, against 40 to 55 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
