Last month, not sure where you are that you have jumping worms.
@haushinka most bagged 'soils' are just shredded wood mulches/composts. Different woods, different shreds, but no soil except what they degenerate into. I use them, also cardboard, but they will sink as much as 6" a year, so be prepared. We also have Monterrey Mushroom Factory south of you in Madisonville, it has less wood and more straw type composition, but has yet to burn anything I grow unless I went and got a 33 gal trashcan of the raw stuff. Black Kow will have a bit more clay in it, which helps the roots have something to grow into. How deep are your beds? 18" deep? 24" deep or just a foot? It matters when you start watering this summer, the deeper they are, the more water you will need as that bagged 'Raised/Container Gardening bagged stuff' lets water drain FAST. That stuff works much better turned under in your own soil. Another type of additive that I am appreciating is bagged leaf mold compost. It works wonders if you can find any up there in Ennis.
