Sowing: Direct sow in late fall, pressing into the surface of the soil since this seed needs light to germinate. For spring planting, mix the seeds with moist sand and store in the refrigerator for 30-60 days before planting. Keep the soil lightly moist until germination. This seed can also be started indoors 6-8 weeks before planting in the spring.

Growing: Water seedlings until they become established. This plant develops rather slowly, and usually begins blooming in its second year. Mature plants tolerate drought well, though they also appreciate occasional watering in especially dry weather. After blooming cut the plant back to several inches above the soil, unless seed is wanted. Do not overwater, since this plant is particularly susceptible to root rot if the soil becomes too moist. If seeds are not required, cut the plant back after blooming has finished. This plant often self-sows, and is highly attractive to bees, hummingbirds, and butterflies.

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.


If you can’t find germinating and instructions online you can find them on the item page. Our goal is to save money everywhere we can so we can pass those savings on to you.
