Each window is a planning range. Check the forecast, soil and cultivar before planting; a later date is not automatically safer in hot or wet conditions.
Plant the bulbs

Seasonal context
Rainfall and the growing season in Peterhof
August has the highest average precipitation (90 mm); February has the lowest (38 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 tulips for Peterhof
- August is the wettest month in the rainfall grid, averaging about 90 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 tulips
Use the calendar to plan ahead, then check the conditions in your own garden.
- 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 tulips for a single display or a return next year
Plant sound bulbs in a sunny, drained position at the supplier's recommended depth. Wet soil can rot bulbs, and unsuitable winter conditions can prevent the expected flowering cycle even when a planting date looks favourable.
Remove spent flower stems if seed is not wanted, but leave green foliage until it naturally yellows. Keep planting positions marked during dormancy. Record which cultivars actually return with worthwhile flowers instead of replacing all bulbs automatically.
What to record this season
Which cultivar returned well, and did drainage or winter conditions differ between planting sites? Add the cultivar, sowing date and conditions to your growing record so you can compare next season.

Why these dates
Plant sound bulbs in a sunny, drained position at the supplier's recommended depth. Wet soil can rot bulbs, and unsuitable winter conditions can prevent the expected flowering cycle even when a planting date looks favourable.
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.
Tulips are anchored to the first autumn frost rather than the last spring one, so the planting window on this page counts backwards from the end of the season in Peterhof instead of forwards from its start.
Peterhof is zone 5b, 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 167 days, against 150 to 200 days to first flower for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
