Q.Weeds Indicating Soil Deficiencies
I have lettuce and greens in a bed where everything seems to be growing too slowly. Lots of red root pigweed, little grass blades, purslane, and lamb’s quarters are coming up as weeds in there. I’m wondering if these weeds indicate any deficiencies or soil character? Earlier this season we tested the bed, it was still a bit acidic (5. 5 – 6. 0). We added lime and planted.
