Following the planting month advice above for my region, I planted snowpeas last September (or possibly October) and have just had to pull them all out as they developed a bad case of powdery mildew. Upon further reading elsewhere, this makes sense, as snow peas are not meant to be grown in hot weather, and it is now summer. Given that they are harvestable in 3-4 months, I think the absolute latest that one should sow them is August (in this region). They could possibly be sown as early as February and March, though. Another useful bit of advice I discovered was to completely avoid foliar watering, since snow peas are so susceptible to fungal diseases.

Powdery mildew can be a problem if you water from above, wetting the foliage in the process. But yes, it does seem a bit late in the year. I've never started them as early as Feb in Canberra though.

If this is a common experience, the dates will be adjusted. Remember that there are variations in the climate from year to year, and the planting dates are recommendations only.

I suggest adding something like "water the roots only, avoid wetting the leaves and stems" to the tips section, too.

The Peter Cundall site recommends sowing snow peas (in a cool climate) only in August. I might experiment with a few months before that as well, since I have plenty of seeds. (And avoid foliar watering, of course.)
