The later hail occurs, the higher the chance of yield loss, given that the plants have less time to recover. Hail on seedlings rarely results in yield loss. Heavy hail at the 6-leaf stage will have more yield loss but recovery can occur…

It may seem that canola grows slower than wheat, but consider what variables may influence this observation. Wheat is often seeded earlier, which is one major reason why it may…… -
A few days in waterlogged soil can be enough to kill young canola plants… -

Canola seedlings at the canolaPALOOZA site in Lacombe, Alberta, were hit by three -4°C frosts and one -3°C frost over a five-night period May 10-14. Yet photos taken the morning of May 16 show that a decent number of seedlings survived… -
The week after seeding is a good time to verify seeding depth and to check seeds and seedlings for rots and blights. Disease damaged seed and seedlings die quickly, and may be gone within a few days, which is why this timing is important to an accurate diagnosis… -
Seeding early May versus late May or early June, providing that crop conditions allow for it, is a relatively low cost way to increase yield and profit from the crop… -
Yield potential for canola seeded in late May is not as high, generally, as canola seeded in early May, but it is still pretty good and better than for canola seeded in June. Given the current date, the argument in favour of reseeding a crop clearly thinned out and set back by frost or any other issue may have more…

After a frost, it can take a few days to accurately determine how many plants survived, and whether the stand is still uniform. Be patient before making any decisions…
