Ok here we go again, I learned from you all not to bother putting pebbles, rocks etc in the bottom of my pots for drainage. But now I noticed another situation. I hand watered my pots because the water hasnt been turned on here yet, the top inch of soil got wet, then the rest of the water drained right through. Leaving the rest/layers of the potting soil (from last year) dry.

Should I take the soil out of the pots (and therefore also the rocks) and put fresh potting soil in?
