Action plan

Can I plant this now?
Use your local last-frost, first-frost, and soil-temperature checks before treating this crop as plantable today.
Start indoors or direct sow?
Start indoors, harden off, then transplant into the final bed when local timing is safe.
How much space?
18 inches in-row spacing, 24 inches between rows, and 0.125 inch seed depth.
Best companions?
Use this as part of a diverse flowering or herb planting, and treat companion claims as site-specific rather than guaranteed pest control.
Common failure modes?
Seed can self-sow in mild gardens; deadhead if spread is unwanted. Moderate water while establishing; tolerates drier soil later. Well-drained soil with moderate fertility.
