NSCannaanswered grow question 2 years ago Springtails can come with some soils but usually come with compost, worms or sometimes worm castings depending on the source. They're fine as long as they have compost/mulch to eat, and help decompose organic materials. Keep your soil nutrient rich with organic matter and you'll be fine, but if you starve them, they have been known to eat living plant roots. My living soil is full of soil mites, worms and springtails=)
