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.

Monthly growing conditions in Mexico City

Compare the planting window with the local temperature pattern. These are historical monthly averages, not this year's forecast or measured soil temperatures. Average frost days do not tell you whether a particular night will freeze.

For gauras, also check drainage, sunlight and cultivar requirements. See the rainfall context above; humidity, irrigation and local pest pressure are not calculated.

Local growing check

Before choosing gauras for Mexico City

  • 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 gauras

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

  • Measure the soil at sowing depth. Aim for at least 13°C (55.4°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.
  • Check mature size, drainage and cultivar suitability before choosing a permanent position. A suitable planting window does not guarantee long-term survival or fruiting.

Use a sunny, drained site to keep gaura balanced

Provide full sun and free drainage. Excessively rich soil can favour loose growth, and established drought tolerance does not remove the need to water young roots. Avoid unnecessary disturbance of its deep root system when arranging neighbouring plants.

A light trim of spent growth can renew the display while the plant remains active. Check the crown after wet or cold periods and compare winter survival between planting positions. Record the cultivar and site together, since one good summer does not establish reliable long-term performance.

What to record this season

Did the cultivar remain balanced without heavy support, and did its crown survive the wet season? Add the cultivar, sowing date and conditions to your growing record so you can compare next season.

Why these dates

Provide full sun and free drainage. Excessively rich soil can favour loose growth, and established drought tolerance does not remove the need to water young roots. Avoid unnecessary disturbance of its deep root system when arranging neighbouring plants.

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. Gauras are timed with planting out 2 weeks after it, and this page simply resolves those offsets against the frost date computed for Mexico City.

Mexico City sits in zone 9b, 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.

Growing gauras in Mexico City

Can I grow gauras in Mexico City?

The calendar estimates a planting window, not a guarantee of success. 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.

When should I plant gauras in Mexico City?

Aim for 23 Feb - 23 Mar in an average year. If you would rather not gamble on the weather, wait until 20 Mar - 17 Apr - by then frost has finished in nine years out of ten.

When might gauras flower in Mexico City?

The estimated period is 1 Jun - 31 Oct, based on 100 to 130 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 gauras 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.
