So I've been keeping about 1 inch of pine needles as mulch for my potted seedlings. As they sprout should this be a concern? Some are starting to come up in the photo below. Should I remove some of the pine needles, all of them? They're not greenhoused so I don't know if there's a great chance of loss if a big freeze comes. They survived the 8 degree temps, but weren't showing like now. Suggestions please
They're lacking color only because not getting light and needles were pressing them down.
