Sowing: Direct sow in late fall, pressing into the surface of the soil since this plant needs light to germinate. For spring planting, mix the seeds with moist sand and store in the refrigerator for 30 days before planting. Keep the soil lightly moist until germination, which usually takes 2-3 weeks. The seeds can also be started indoors 6-8 weeks before planting in spring. Keep seedlings lightly moist, and transplant them as soon as they have developed several leaves.

Growing: Water seedlings regularly until they become established. This plant grows very quickly and needs little care. Though it grows well in fairly dry soil, it performs best with occasional watering in dry weather. This plant usually begins blooming in its second year of growth. Mature plants tolerate heat and drought well, as well as tolerating clay or rocky soils. Deadhead for the longest blooming period. Mature plants can be divided. This plant attracts butterflies, and may self-seed.

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.
