Seasonal context
Rainfall and the growing season in Aguascalientes
July has the highest average precipitation (131 mm); April 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 swiss chard for Aguascalientes
- July is the wettest month in the rainfall grid, averaging about 131 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 swiss chard
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.
Harvest stems and leaves without exhausting the plant
Sow or plant into fertile, well-drained soil and thin crowded clusters. Space plants for the harvest size you want: baby leaves and large cooking stems are different targets.
Take outer stems cleanly while leaving the growing centre intact. A small repeated harvest lets a healthy plant replace leaves instead of forcing it to recover from complete stripping.
Keep moisture steady and check for leaf damage and flowering stems. When the plant bolts or leaf quality declines, judge whether another sowing is more useful than keeping an old plant indefinitely.
Growing in a container
Chard can be productive in containers. Leave room for individual stems to expand and reach the plant easily without breaking neighbouring leaves.

Why these dates
Sow or plant into fertile, well-drained soil and thin crowded clusters. Space plants for the harvest size you want: baby leaves and large cooking stems are different targets.
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. Swiss chard are timed from 5 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 Aguascalientes.
The median frost-free season here is 296 days, against 50 to 60 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
