Sowing: This seed should be sown directly outdoors, since the long roots of this plant need space to develop and dislike being disturbed. In late spring after the soil has warmed to 70-75 degrees F, plant several seeds together 1" deep and 6" apart in rich, well drained soil; the seeds will begin to germinate in 8-10 days. The protection of netting or a screen may be necessary to prevent birds or animals from eating the seeds as they begin to sprout and develop; keep the soil moist. Thin to the strongest seedlings.

Growing: Water the seedlings occasionally as they develop. Mature plants tolerate drought well, though they may need regular fertilizing for the best growth. Avoid overwatering, since this can cause disease. This plant attracts bees, butterflies, and birds.



All multiple orders of the same seed are put in the same bag. For example if you order 500 beefsteak tomato seeds x 3 then 1500 seeds will be put in the same bag. We do not send out 3 individual bags with 500 in each. This goes for all seeds unless they are listings of different seeds.
