I have 3 Raised beds. 1 with beetroots and carrots, 1 with lettuce and
other salad leaves (mizuna, corn salad, rocket, oriental mustards) and 1
with corn and french beans.
I poured in loads of topsoil (40%) compost (60%) mix back in February.
My garden is now going great guns. However, I am not sure if I need to
add any fertilizer to any of it at any point, and if so…what?
