Back with the veggies, I've finally got around to sowing my sweetcorn.
I know I'm later than some, but I tend to find that early sowings slow up once they are transplanted. Mine may go in the ground later, but they take off straight away and usually catch up the early birds. The other drawback of getting them in the ground too early, is that they are more vulnerable to slug and snail attacks while they sit there in the (usually) wetter part of spring.
Mine are sown in my homemade paper pots (as used for my French climbing beans) so that the roots don't get disturbed when transplanting later in the season.
To help with germination I rehydrate the seed overnight. I simply get an old Flora tub (other buttery spreads are available), line it with some doubled-up kitchen roll, and pour some water in. Not so that it's swilling about, just so that the paper becomes totally saturated. I then place the seeds on the wet paper and leave for 24hrs before sowing.
This is the only seed I treat in this way. I've read about people germinating their parsnip seed prior to sowing, but I've never had a problem with parsnips. I stick mine staright in the ground - this year they went in on April 8 and they were coming up quite nicely when I was down the allotment last week.
Sometimes I think we can make things too complicated. At the end of the day, seeds are desperate to grow. It's what they do. Only the poorest of conditions will stop them.
