How to Grow Sea Buckthorn

Sea buckthorn seeds require 90 days of stratification at 5°C/40°F to overcome dormancy, or you can soak them in water for 48 hours before sowing them. They need some light to germinate, so make sure you either surface sow them or lightly cover them with soil. I’ve found that soaking the seeds works quite well instead of the hassle of stratifying them.

Sea buckthorn is a perennial shrub that is hardy in zones 3 to 8. The plant prefers light, sandy soil. Sea buckthorn will grow best in full sun, as it needs a lot of energy to produce a large crop of berries. It cannot tolerate shade at any stage of growth. Before sowing, soak the seeds should in water for 48 hours, and at this time, discard seeds that are floating. Surface sow the seeds onto a sterilized garden soil mix. Always keep the soil moist but never soggy. It’s essential not to let the soil dry out, or the seedlings will die. When the seedlings have a few sets of leaves, transplant them outside in spring after the risk of frost has passed. Spacing: 1 m (3′) between plants, 4 m between rows.
