Sweetcorn - how long...

[SimpleSimon]

From the silks emerging to harvest, roughly?

The corn in my tunnel is 7ft high and raining polen everywhere. The silks are just emerging today. Trying to plan a succession, likely dwarf beans as my outdoor climbing beans are doing awful!

Temperature seems to be the key, the old thumb nail test is really the only way of telling when it's ready. Two plants side by side can be ready at different times by some distance, some of my plants are twice the size of others, all from the same packet sown at the same time.

I seem to recall it'll be about 3 weeks from now roughly? Means I need to get sowing for the succession. If its much longer I'll wait. Maybe it is longer. I should know this but for some reason I can't seem to remember.

My notes say I sowed a succession of dwarf beans last year on the 27th July. But this year's corn is way ahead it seems. Not sure why. It's also about twice the height. Looking like I might even get 3 cobs on some of them. I have fed them heavily with chicken manure pellets this year. A good couple of kilos total for the 16 plants ( across 3 doses).

I usually judge it by the state of the silks rather than time.
When the silks are completely dead and brown, and almost fully shriveled off, they are probably ready, and so should be tested for readiness with the usual juice colour test.

I understand, just looking for a rough estimate. My head is saying 3 weeks but I might be talking rubbish. A month? 3 months? Just a very rough estimate. I'll certainly be waiting until they go brown. I recall last year it wasn't long from harvesting the corn in the tunnel to the outside batch. This year the corn outside isn't even knee height. Very strange year.
