Ken - thank you so much for advices. For now I willlet seedlings as they are, will se if the ones in the pot will recover a bit (I hope!).
The ones in vermiculite are there since the end of february.
I like the native soil even if it's not so good to look at, and it's hard to work when I need to dig for planting, but as I said before is full of earthworms and I believe it means it's quite rich. I couldn't find alfalfa pellets because I have to find an equivalent italian product and understand what it really is (is it a horse food?). So I should mulch all the year long?
Sue - I can see the point, and I don't believe in miracles if they are on the producer page, with so few details. I read a lot of italian forums and people who's using this fertilizer see the difference, but it's quite costly for a garden. many says the same good result are obtained with a granular fertilizer called NPK gold which is a 15-9-15 with micro nutrients and magnesium too. The N in there is of two types, one is immediatley available and the other is a slow release N. Not that it costs less, it's about 1€ per Kg, but for a garden makes more sense!
