Seasonal context
Rainfall and the growing season in Lévis
July has the highest average precipitation (124 mm); February has the lowest (64 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 love-in-a-mist for Lévis
- July is the wettest month in the rainfall grid, averaging about 124 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 love-in-a-mist
Use the calendar to plan ahead, then check the conditions in your own garden.
- Measure the soil at sowing depth. Aim for at least 7°C (44.6°F); the calendar estimates soil warmth from air temperatures and cannot measure your bed.
- Frost tolerance does not make saturated or frozen soil suitable for planting. Wait until the bed can be worked without smearing or compacting it.
- 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.
Choose between more flowers and decorative nigella seed pods
Sow where plants will grow when local conditions suit a cool-season annual. Avoid unnecessary root disturbance and thin seedlings before they become crowded. A sunny, drained bed with moisture during establishment supports more useful growth than a packed sowing.
Remove some fading flowers if continued flowering is the aim, or retain selected capsules for dried arrangements and seed. Mature pods can scatter seed through the bed. Record which sowing flowers before sustained heat rather than treating every frost-free month as equally suitable.
What to record this season

Why these dates
Sow where plants will grow when local conditions suit a cool-season annual. Avoid unnecessary root disturbance and thin seedlings before they become crowded. A sunny, drained bed with moisture during establishment supports more useful growth than a packed sowing.
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. Love-in-a-mist are timed for direct sowing 3 weeks before it, and this page simply resolves those offsets against the frost date computed for Lévis.
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.
Lévis is zone 4a, 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 median frost-free season here is 145 days, against 70 to 90 days to first flower for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.

When might love-in-a-mist flower in Lévis?
The estimated period is 12 Jul - 1 Aug, based on 70 to 90 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 love-in-a-mist 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.
