Comments: Seed count varies from 330-400 seeds per lb. pending crop year. Do not over dry seed. Seed that has been stored for up to 2 years cold and moist has been sown with satisfactory germination. For seed stored over 1 year float in water and toss floaters/keep the sinkers.Seed from storage tends to have little to no warm stratification requirements and a shorter cold stratification period. Mold problems can be controlled in a 5-7 minute 1:10 Bleach:Water dip with a thorough rinse after the dip. Warm soil temperatures may inhibit seed germination so sow pre-treated seed in the early Spring and not late when soils warm up if possible. Seedlings may benefit from partial shade the first year. One of the oldest tree species, the Ginkgo has existed for 150 million years and at one time was native to North America. Note: I had several small seedlings growing in a dish in the window that dropped their leaves in the Fall but never broke bud in the Spring. One day (late Summer)the cat jumped up on the window sill and promptly ate the top bud of one of the plants. Within 2 weeks the lower buds began to break and the plant started to grow again. I removed the top buds from the rest of the seedlings and all responded by breaking bud and growing again.
Germination info: Fresh seed requires 30-60 days warm stratification followed by 60-90 days cold stratification. Seed from 3-6 months cold storage may germinate in warm stratification so pay attention !
A Trial Packet contains a minimum of 5 - 30 seeds depending on the size of the selected seed.
