Hi Everyone: I had a construction worker build a rather nice raised bed garden. However, the soil looks like regular mulch. Can someone recommend what you should add, soil wise, into your raised bed garden? What do you add when the ground just isn’t enough? Help!! My plants sprouted, but really aren’t flourishing and growing. Thanks, Marty
I would do a soil test. This question on the forum has some links about Soil Testing.
If the bed is filled with just mulch then it may be decomposing (it will feel hot if you stick your hand into it) and using up all the nitrogen. This would cause the plants to just sit there, not growing. If this is the case, then add blood meal and don’t expect too much this first year until the composting slows down a little.
When you are ready to add soil to the bed, the second page of the Cornell Fact Sheet on raised beds talks about what type of soil is needed for raised beds.
