Reusing old potting compost
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?
