Agretti through the year
Against the frost risk in Kolomna
Why these dates
Sow fresh seed four weeks before the last frost, thickly, because germination is poor even at its best. Cut the whole plant at about 20cm before it toughens.
Tolerates around -3C. The season ends in early summer when the plant turns woody rather than because of any cold.
Seed packets and extension guides express timing as weeks either side of the last spring frost, because that is the only reference point that travels. Agretti are timed for direct sowing 4 weeks before it, and this page simply resolves those offsets against the frost date computed for Kolomna.
With one correction, which is the note at the top of the page: the offset alone would put this crop in soil that is still too cold for it. Where the frost date and the soil temperature disagree, the dates here follow the soil, because a seed in cold ground either rots or waits, and a sowing made a fortnight later usually overtakes it.
The median frost-free season here is 157 days, against 50 to 70 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.

Growing agretti in Kolomna
When should I plant agretti in Kolomna?
Aim for 3-24 May in an average year. If you would rather not gamble on the weather, wait until 2-23 May - by then frost has finished in nine years out of ten.
Can I plant agretti earlier in Kolomna?
Frost is finished by about 5 Apr, but the soil is still too cold. Agretti will not start until it reaches 10°C (50°F), and here that is around 3 May. Going in earlier usually means seed that rots or transplants that sit and sulk, and a later sowing catches them up.
When will agretti be ready to harvest in Kolomna?
Expect to start picking around 1 May - 31 Jul, based on 50 to 70 days to maturity from the planting date calculated for this location.
How much frost will agretti tolerate?
