Answer: If a seed packet says to plant when the soil can be worked in the spring, it is referring to the time after the ground has thawed (for areas in which the ground freezes - as it usually does in zone 6 sans El Nino). This is usually mid-March for your area. Incidentally, I checked, you are in zone 6. Last frost dates for Ohio range from 5/10 in Sandusky to 6/8 in Athens, for a date for Strongsville, call the Cuyahoga Co. Extension Service at ph. 216-397-6000. Plant potatoes several weeks before the last expected frost date for your area, but only if the ground is not wet. If you are having a wet spring, wait a few weeks or the potatoes will rot. Plant the onion sets about 2-3 weeks before the last expected frost date, once again, hold off if the ground is soggy at that time.
