Unfortunately they're pretty darn vulnerable and sweet tasting to chompy mouthed critters at this stage. I have learnt that I need to scatter some snail and slug pellets around the pots and I will investigate some copper tape or wire which is supposed to deter them too. DE should help.I'm not sure if I'm seeing insect damage, or if it's damage from trying to get out of the seed, whatever it is, I went crazy with the diatomaceous earth, just in case. Any creepy crawlers will be eviscerated.
It's only on the cotyledons, so I'll just keep an eye on it for now.
I notice she's very delicate compared to other seedlings I've grown, but she has a strong stem and isn't spindly or stretching too much.
Apart from the cotyledon damage, she seems happy enough.
