Seaberry / Sea Buckthorn Plants

Sea berry, Hippophae rhamnoides, are either male or female so males are needed for pollination. Males need to be planted at a rate of 1 male for every 6 females, six feet apart. Sea Berry is wind pollinated and bears approximately 3 years after planting. Sea berry is hardy to minus 40 F, grows in USDA zones 3-9 (but best in 3-7), likes full sun and well-drained soil. Ideal pH is between 6.3 and 6.8 but tolerates 5.5 - 8.5. Height 8-12'. Spread 5+'

The vitamin C concentration of sea berry fruit is 30 times higher than the amount of an orange, 25 times that of a strawberry, and 5 times that of a kiwi. Their vitamin E content exceeds wheat, corn and soybeans. Many people prefer seaberry juice to orange juice, and some enjoy eating the berries fresh off the tree.

Planting Info expert advice from our propagator

Yes, the roots can increase nitrogen levels in the soil. However, young sea buckthorn plants need a well-balanced amendment for a few years to begin growing the Frankia nodules from the bacterium in the soil they are planted in.
A loam to lightly sandy soil with decent amounts of organic matter to retain nutrients and a balanced pH is best for starting sea buckthorn shrubs off on the right foot and keeping them growing well for years.
Soak roots in water for about 2 hrs before planting
Dig holes large enough to fit all the roots and the rooting part of the stem: roughly 12" x 12" deep or larger
Mix some bone meal and good compost with the soil in the hole and add the plant
Pack the soil well around the stem.
Water thoroughly. Continue watering every two days for two months.
Add a good wood chip mulch as a weed barrier 3" thick x 16" D.
Each spring for the next three years, you can pull back the wood chips, add a compost top dressing, and return & add the wood chips over the top to maintain a cover of 3" thickness. The nutrients will leach through over time. Compact any freshly laid mulch down in a funnel shape around the trunk of the sea buckthorn plant to provide air to the base. This will help avoid excess moisture from forming there. Thus, reducing the migration of fungal growth while directing water to the center of the root system below. Once the Sea buckthorn shrubs have reached a mature height, mulch is no longer necessary, but adding a shovel full of compost each spring will keep your shrubs looking healthy and vital.

Growing Info Regular deep watering during the hot dry spells of summer will increase seaberry yields substantially. Phosphorus and Potash, along with micro nutrients are necessary, while Nitrogen can actually hinder the plants growth and general vigour.
Please note that some varieties of seaberry sucker, up to 15 feet or more, so should not be planted next to your neighbor's property line! Suckers are best controlled by simply mowing the grass around the bush. However, sea buckthorn should not be confused with the black-berried common buckthorn Rhamnus cathartica L. which is considered a noxious weed.

Maintain reasonable control over the sucker plants by cutting out horizontal rhizomes beneath the turf’s surface or mowing around the shrub’s base.

Keep a watchful eye on the young plant the first year it is put in the ground; it will be vulnerable to drought, weed overgrowth, ice & heavy snow, rodents and deer chewing at the young bark and branches…Also lawnmowers!

Rejuvenation: The rejuvenation cut back should happen around the 7th or 8th year. Sometime before spring break, cut back the entire plant to roughly 10-12" above the natural crown of the primary branches (the shrub will end up at roughly 3-4' H). All small branches should be cut to leave only primary trunks large enough to support regrowth. It is important to note that only healthy and well cared for trees will continuously regrow.
