Put up some herbs in those little compacted peat pods that you can buy at Home Depot. Again, the problem of how to re-pot them once they achieve leaf status. My new home has tough clay soil and I may do another year of herbs in pots.
Just pinch out/cut the bottoms (for root growth)
Slice the sides so that lateral roots can reach enriched soil/ compost / fertilized soil ,
and make sure no peat is exposed above soil level as it will wick away moisture, and dessicate the plant.
