I started container gardening on my patio last season for a lot of vegetables but have now built several raised beds to use permanently. The raised bed is on mowed and weeded old lawn, so it’s seating in the soil. the potting mix was homemade mixture with horse manure, coco coir, topsoil, spent mushroom compost and organic fertiliser and I grew seeetcorn,carrots and tomatoes.
Can I reuse this mix to fill the raised beds?

Yes. if you can try to add some fertilizer of your choice to give back some nutrients to the spent compost .
Thank you Jason, it’s a relief; I’ve been dreading the cost of filling the raised beds.
Unless there is obvious disease present, any used potting compost can be re-cycled as a soil conditioner in open or raised beds. For highly productive veggie beds you just need to add a well balanced fertiliser as Jason suggests and maybe some lime or calcified seaweed if you're growing brassicas.

Thank yoI Obelixx, non of the plants had any diseases. In fact I was impressed with the harvest. But then I did natured the plants like a baby, I didn’t want my first trial to fail.
I used calcified seaweed for the tomatoe compost mix.
