>>914576(Not that guy) I often give my soil a good microwaving/oven baking before using it to start seeds, that should kill most shit and I don't have to buy any expensive special substrates
Wish there was better weather here, winter is so boring garden-wise, other than a few onions, corn salad and parsley going very slowly, nothing really grows and it'll look sad like that until March/April - you're not missing out on much
