Sowing: Direct sow in early spring, pressing lightly into the surface of the soil since this seed needs light to germinate. Keep the soil lightly moist until germination, which should occur within 10-30 days. When the seedlings can safely be handled, thin or transplant for wider spacing. For an early start, start the seed indoors 8-10 weeks before the last frost and transplant outdoors.

Growing: Water the seedlings until they become established. Mature plants can tolerate almost any type of soil, though they tend to wilt in extremely dry soil. This plant needs little care and grows easily; it can quickly spread and become invasive if not controlled, since it reseeds prolifically. To help prevent this, the plants can be cut back after blooming. This plant attracts birds and resists deer.

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.
