Rue should be sown indoors in soil trays or pots 10-12 weeks before the last frost of your spring season. You can sow the seeds 1/4 of an inch under the soil and they will germinate in 14-21 days if kept abover 70 degrees Fahrenheit. You can transplant your seedlings outdoors after the last frost of the season and place them 12-24 inches apart. Plant your Rue out in full sun. A NOTE OF CAUTION: The oil from rue leaves may cause a photosensitive skin reation in some so use caution when burshing up against the leaves on warm, sunny days.
