How to Grow Bur Oak Seeds!
# 1 | Seed requires 24 to 60 days cold moist stratification. Stratify bur oak seeds by placing them in a moist mixture of sand and peat moss and then storing them in a cool location. You can store them in the refrigerator in plastic containers or food storage bags.
#2 | After cold stratification, the best time to bur oak seeds outdoors is after the last frost in your area (spring). In the Northern states – the best time to plant seeds outdoors is from May to June. Alternatively, if you receive your seeds in the fall, you should plant your seeds outdoors before the ground freezes in your area (late September to early November) and this will naturally stratify the seeds.
#3 | Place your seeds 1 inch to 1 ½ inches below the soil surface. Gently water your seeds to keep moist, not soaking wet. Heat & humidity is critical for germination. Germination may occur in 1 week or as long as 3 months
