I have Roots Organic 707 in my beds which unfortunately is super dry even with good soak downs of water.
The lack of nutrients is unfortunately affecting my seedlings.
What can I amend it with to get it to be come moist and attractive to microbes and earthworms so my seedlings can grow better & get the deep green foliage?
compost and clay will both help. That stuff is made to shed water, it's a real nuisance if it is let to fully dry out. But compost, worm castings, powdered clays, and biology from teas and mulches will help over time. The main thing with that kind of potting soil is to never let it fully dry out or it takes forever to lose it's hydrophobic qualities.
s lowe gave you some great suggestions. I would like to add that adding coffee grounds will help and then top it off with wood chips.
