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.

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 tickseeds 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 tickseeds
Use the calendar to plan ahead, then check the conditions in your own garden.
- Measure the soil at sowing depth. Aim for at least 12°C (53.6°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.
- 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 deadheading and renewal to sustain coreopsis displays
Use well-drained soil and avoid persistently wet crowns. Water new plants to establish roots, then adjust to conditions rather than keeping the bed constantly saturated. Check the cultivar's eventual height before placing it along a narrow path.
Remove spent flowers to encourage further display when growth remains active, or retain selected heads for seed. Seedlings may differ from a named cultivar. Divide healthy clumps when appropriate and record which plants return well rather than repeatedly feeding a declining crown.
What to record this season
Did deadheading extend flowering, and which plants remained vigorous in the next season? Add the cultivar, sowing date and conditions to your growing record so you can compare next season.

Why these dates
Use well-drained soil and avoid persistently wet crowns. Water new plants to establish roots, then adjust to conditions rather than keeping the bed constantly saturated. Check the cultivar's eventual height before placing it along a narrow path.
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. Tickseeds are timed from 8 weeks before that frost for an indoor start, with planting out 2 weeks after 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 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 tickseeds in Gyumri
Can I grow tickseeds 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 tickseeds in Gyumri?
Aim for 3 Jun - 1 Jul in an average year. If you would rather not gamble on the weather, wait until 19 Jun - 17 Jul - by then frost has finished in nine years out of ten.
Can I plant tickseeds earlier in Gyumri?
The historical frost estimate is 1 Jun. For Tickseeds, an air-temperature model estimates soil warmth of about 12°C (53.6°F) around 3 Jun. This is not a soil measurement or a forecast. Check your bed at sowing depth; cold, wet conditions can slow growth and increase decay risk.
When might tickseeds flower in Gyumri?
The estimated period is 1 Jun - 30 Sep, 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 tickseeds 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.
