Seasonal context
Rainfall and the growing season in Schenectady
June has the highest average precipitation (120 mm); February has the lowest (68 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 mizuna for Schenectady
- June is the wettest month in the rainfall grid, averaging about 120 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 mizuna
Use the calendar to plan ahead, then check the conditions in your own garden.
- Measure the soil at sowing depth. Aim for at least 4.5°C (40.1°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.
Harvest mizuna at the leaf stage you prefer
Keep the shallow root zone moist in a fertile drained bed. Some light shade can help in hot periods, but do not assume relative heat or bolt tolerance means the plant can be neglected through drought.
Pick tender leaves while preserving growing points for regrowth, and inspect for flea beetle or caterpillar damage. Record when older leaves become fibrous. A fresh small sowing may give better quality than repeatedly cutting an exhausted stand.
What to record this season
At what leaf size was the texture best, and how many useful cuts followed? Add the cultivar, sowing date and conditions to your growing record so you can compare next season.

Why these dates
Keep the shallow root zone moist in a fertile drained bed. Some light shade can help in hot periods, but do not assume relative heat or bolt tolerance means the plant can be neglected through drought.
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. Mizuna are timed for direct sowing 4 weeks before it, and this page simply resolves those offsets against the frost date computed for Schenectady.
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.
The median frost-free season here is 171 days, against 35 to 45 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.

Growing mizuna in Schenectady
Can I grow mizuna in Schenectady?
The calendar estimates a planting window, not a guarantee of success. June is the wettest month in the rainfall grid, averaging about 120 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 mizuna in Schenectady?
Aim for 2-30 Apr in an average year. If you would rather not gamble on the weather, wait until 17 Apr - 15 May - by then frost has finished in nine years out of ten.
When might mizuna be ready to harvest in Schenectady?
The estimated period is 1 May - 30 Nov, based on 35 to 45 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 mizuna 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.
