I'm guessing they do. i just figured the high wind when it dropped below 20f is what got them. it usually doesn't get that cold. now I'm just protecting younglings when it drops below 30f to play it safe.Best of luck. I'm sorry to hear of the loss.
In your climate, do your zelkova need protection during the winter? I have a plethora of seedlings myself, although I am probably in a much milder climate as I don't provide protection to them.
nope. i put them in the cells just to see which will germinate. i use just a little bit of straight perlite to start them so i don't waste too much substrate. i also think the cells are too small to keep them healthy till next year. i also plan on wiring these later this year.I would think placing the seeds in individual cells initially was so you could grow them there this year?
I started a bunch of JM and JBP from seed in similar cell trays a few seasons ago and they grew terribly all season so I can confirm your thoughts that cell trays are not ideal for anything other than germination.nope. i put them in the cells just to see which will germinate. i use just a little bit of straight perlite to start them so i don't waste too much substrate. i also think the cells are too small to keep them healthy till next year. i also plan on wiring these later this year.
