Seedlings can be very susceptible to slugs, so you’ll want to be careful to get rid of any slugs that might otherwise devour your garden. The video recommends a safe, organic slug killer. But if you can’t find that locally, you can also use a flat tray filled with beer, which attracts the slugs inside and then drowns them.
Once your seedling plants start growing, you’ll need to go through and thin them out so that they have at least a couple of inches on each side of the seedling. It seems mean to pull up the other plants, but if you don’t, you’ll end up with plants that are so crowded that they will die out and not succeed.
You’ll also see early weeds at the beginning of the season with your garden. Pull them out by hand, or chop through the roots with a hoe or other weeding tool so that they don’t immediately grow back.
