Hi all, second year with these raised beds but first time using drip irrigation. The bed is 4x4 and the drip tubing has 6 in spaced emitters. I don’t feel like the water is really penetrating the soil- it seems to just run down and out the sides of the bed. The soil seems dry almost immediately after watering. I did not amend with compost before planting some spring veggies (realizing now we should have done that first). Anything I can do now to help with water retention or should I just start over?
We have two other 4x4 beds that haven’t been planted yet- how should I prep them before planting to avoid this problem with the others?
TIA!
