Seasonal context
Rainfall and the growing season in Gyumri
May has the highest average precipitation (77 mm); February has the lowest (23 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 orlayas for Gyumri
- May is the wettest month in the rainfall grid, averaging about 77 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 orlayas
Use the calendar to plan ahead, then check the conditions in your own garden.
- Measure the soil at sowing depth. Aim for at least 5°C (41°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.
- 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.
Choose orlaya's sowing season for the display you need
Choose an open, sunny position with well-drained soil; the RHS notes that poor soil can be suitable. Its UK guidance distinguishes autumn sowing for earlier, larger plants from spring sowing for a later display. Use that comparison with local winter advice rather than copying those months worldwide.
Remove finished flowers or cut down spent stems if seed is not wanted. Record plant height, first flowering and useful cutting stems for each batch. If you want to compare seasons, keep the strain and site consistent so the result reflects timing rather than several changes at once.

Why these dates
Choose an open, sunny position with well-drained soil; the RHS notes that poor soil can be suitable. Its UK guidance distinguishes autumn sowing for earlier, larger plants from spring sowing for a later display. Use that comparison with local winter advice rather than copying those months worldwide.
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. Orlayas are timed from 8 weeks before that frost for an indoor start, with planting out 2 weeks before it, and this page simply resolves those offsets against the frost date computed for Gyumri.
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.
Gyumri is zone 6a, 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 132 days, against 90 to 120 days to first flower for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.

Growing orlayas in Gyumri
Can I grow orlayas in Gyumri?
The calendar estimates a planting window, not a guarantee of success. May is the wettest month in the rainfall grid, averaging about 77 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 orlayas in Gyumri?
Aim for 27 Apr - 25 May in an average year. If you would rather not gamble on the weather, wait until 15 May - 12 Jun - by then frost has finished in nine years out of ten.
When might orlayas flower in Gyumri?
The estimated period is 26 Jul - 25 Aug, based on 90 to 120 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 orlayas 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.
