Sea buckthorn (Hippophae rhamnoides), as its title implies, is a shrub with a thorny nature.
It has a variety of different widespread names, together with sea berry, sandthorn, and swallowthorn. However if you happen to ask me one of the best moniker is “Siberian pineapple” – a reference to the plant’s chilly hardiness and the flavour of its berries.
We hyperlink to distributors that will help you discover related merchandise. Should you purchase from one in every of our hyperlinks, we might earn a fee.
These little orange berries – known as sea berries – have made sea buckthorn fashionable due to their “superfruit” standing.
The berries are generally present in baked items and beauty merchandise throughout North America, however sea buckthorn remains to be not a well-known sight in residence gardens.
On this information we’ll talk about methods to develop sea buckthorn. Right here’s what I’ll cowl:
What Is Sea Buckthorn?
Sea buckthorn is a medium to massive shrub or small tree, rising between 13 to twenty toes tall with a variety of about 11 toes.
Its native territory spans the subpolar and temperate areas of the Northern Hemisphere – aside from North America.
Usually discovered naturally rising in subalpine, coastal, in addition to desert areas, this versatile shrub is very adaptable to many climates. It is vitally chilly hardy, thriving in Zones 3 to eight.
Classification of the genus Hippophae remains to be evolving. At present, there are six species within the genus. Of those, Hippophae rhamnoides is probably the most well-known and wide-ranging species. Different notable species embody H. salicifolia and H. tibetana.
Sea buckthorn is a succesful shrub that fixes its personal nitrogen within the soil. Its fast rising root system and suckering behavior makes it helpful in stopping soil erosion and to be used as a windbreak.
If in case you have a small backyard, you may nonetheless plant sea buckthorn, however you’ll have to take away the suckers to stop the plant from spreading. And if you would like fruit, you’ll want two vegetation.
Sea buckthorn is dioecious, which suggests the vegetation are both male or feminine so that you want one in every of every for profitable pollination.
If you’d like multiple berry-producing shrub, intention for a ratio of 1 male for each 4 females in a small backyard.
The flowers are pollinated by wind, so female and male shrubs ought to be planted about six to eight toes aside. If you’d like a dense hedge, intention to plant shrubs three toes aside.
Female and male blooms share sure traits – each are delicate, yellow flowers which open earlier than the leaves seem in mid to late spring. They aren’t simply broken by frost.
Your sea buckthorn will start to flower as soon as it’s 4 or 5 years previous, at which era females will produce berries if pollination is profitable.
The berries – that are often orange though they’ll range in coloration from yellow to purple – ripen in late summer time to fall. The style is a novel melange of pineapple, orange, and lemon – fairly tart with a touch of sweetness!
The berries develop very shut collectively in bunches on thorny branches, making hand harvesting a formidable activity. The reward? The fruits are extremely nutritious and loaded with nutritional vitamins C and E, protein, carotene, fatty acids, and flavonoids.
The intense berries distinction fantastically towards the shrub’s slim, silver leaves.
Though sea buckthorn is deciduous, its lengthy leaves – from three quarters to 2 and a half inches lengthy – might keep on the bush by way of a lot of the winter, together with some berries.
True to its title, sea buckthorn sports activities one-and-a-quarter-inch sharp thorns alongside its branches. Happily, new cultivars are being developed with fewer and extra delicate thorns.
Sea buckthorn belongs to the Elaeagnaceae, aka the oleaster household. Vegetation within the Elaeagnaceae household share a attribute silver or reddish-brown luster which comes from hairs on the plant’s leaves, twigs, and buds.
It’s possible you’ll acknowledge similarities between sea buckthorn and different members of the identical household like silver buffaloberry (Shepherdia argentea) – a North America native – which additionally has edible fruit and is commonly grown as a hedge.
Let’s check out why folks first began cultivating this handy shrub.
Cultivation and Historical past
Sea buckthorn has a protracted historical past of use spanning centuries. The genus title Hippophae comes from “hippo,” the Greek phrase for horse, and “phao,” which suggests “to brighten.”
This refers to its use by the traditional Greeks as horse fodder to advertise shiny coats.
Though it’s slowly changing into extra commonplace in North America, its medicinal and dietary qualities have been identified in China, Tibet, and Mongolia for a whole bunch of years.
Within the 1940’s scientists in Russia started learning the biologically energetic compounds within the fruit, leaves, and bark.
Sea buckthorn was delivered to North America – extra particularly the Canadian Prairies – from Russia within the 1930’s by Frank Skinner, a self-educated plant breeder and horticulturist.
He was on the lookout for vegetation that would thrive within the harsh prairie local weather. The introduction was successful and the shrub was utilized in shelter belts and to stabilize soil within the prairies.
However the potential for the berries as a meals supply, in North America no less than, remained unexplored till Invoice Schroeder, a Canadian researcher and plant collector, noticed how they had been being utilized by Russians within the 1980’s.
Russian astronauts had been utilizing sea berries as a meals complement in house. Realizing the excessive nutrient potential of the berries, Schroeder started breeding sea buckthorn for bigger and sweeter fruit. This gave rise to a variety of Canadian cultivars resembling ‘Harvest Moon.’
In the present day, the ocean buckthorn business is well-developed in each Russia and China. They’ve planted massive business orchards of H. rhamnoides for analysis and improvement of sea berry merchandise.
Sea buckthorn is utilized in China and Russia in a variety of medical purposes resembling to deal with coronary heart illness and heal burns and wounds.
In North America, you could find sea buckthorn oil, comprised of the seeds, in beauty merchandise for rejuvenation of pores and skin, remedy of eczema, and as a UV filter.
The worldwide marketplace for sea buckthorn is projected to steadily develop, so you may count on to see extra merchandise containing sea berries within the coming years.
Now that you simply’ve discovered about a number of the many makes use of for these distinctive shrubs, let’s uncover how we are able to propagate them at residence.
Sea Buckthorn Propagation
H. rhamnoides might be propagated in a couple of other ways. Let’s check out some strategies:
Should you don’t thoughts ready 5 years to know the intercourse of your plant, you can begin sea buckthorn from seed. The upside of this technique is that it’s easy – it simply takes time.
You may both sow sea buckthorn seeds straight open air or begin seeds indoors in winter. Seedlings began indoors have a better likelihood of succeeding, however they require a bit extra work.
For finest outcomes, begin sea buckthorn seeds indoors in winter. To advertise germination, the seeds should first be scarified. To do that, merely rub the seeds gently between two items of sandpaper.
Then, soak the seeds for twenty-four to 48 hours to melt the seed coat. Use room temperature water and alter the water a couple of occasions.
After this, the seeds have to undergo chilly stratification for 90 days.
To chilly stratify seeds, place them on paper towels moistened with water and hold them in a plastic bag within the fridge for 3 months. Test each occasionally to ensure the paper towel stays moist.
After this time, sow the seeds in particular person pots which are as much as 12 inches deep and two to 4 inches huge. Fill pots with a pre-moistened mixture of peat and perlite. Cowl the seeds with 1 / 4 of an inch of the media and hold the pots in a spot with vivid gentle.
Water the media so it stays moist however not moist. The seeds will germinate in about three weeks to at least one month. Develop them in pots for about three months till they are often transplanted open air in spring.
Sow sea buckthorn seeds open air in fall or spring. Scarify the seeds first as mentioned above.
Put together your planting space by smoothing out the soil with a rake. Sow seeds on the floor of the soil a couple of toes aside.
Should you’re sowing seeds in fall, they are going to be cold-stratified naturally over the winter months.
Cowl your planting mattress with six inches of mulch to maintain the soil heat – leaves or straw are good choices. When the snow melts Within the spring, take the mulch off of the planting mattress. Water so the soil is moist however not drenched.
If you’re sowing seeds in spring, you’ll have to cold-stratify them first. After sowing, hold the soil evenly moist however not waterlogged, and the seeds ought to germinate in a couple of week.
If you wish to transfer your seedlings to a different location, permit them to develop for one or two years earlier than transplanting.
From Hardwood Cuttings
Not like seeds, hardwood cuttings will probably be clones of the mother or father plant. So if you wish to ensure that your new sea buckthorn is both a male or feminine, it’s finest to propagate through cuttings. Bear in mind, solely feminine vegetation will produce fruit.
It’s comparatively easy to propagate sea buckthorn from hardwood cuttings, and vegetation began this fashion might fruit sooner than these grown from seed.
When taking hardwood cuttings, it’s essential to decide on cuttings from the decrease, lignified a part of the shoot. This half will really feel inflexible and woody – in contrast to the softer, bendable ends of shoots.
Harvest your hardwood cuttings in early spring earlier than the buds break, and the plant remains to be dormant. It’s a good suggestion to put on gloves to guard your fingers from the thorns.
Be sure that your slicing device is clear and sharp. Take six-inch cuttings from the final season’s development – that woody, hardened half – making the lower slightly below a bud.
To root your hardwood cuttings, soak them in room temperature water with two or three buds above the water degree for six days till the buds swell, ensuring to alter the water daily.
In a couple of week, you’ll see roots forming. When the roots are an inch lengthy, you may plant the cuttings in pots and hold them indoors in a vivid, sunny location.
Your planting tray or pot ought to be six inches deep. Use half perlite, half vermiculite on your propagation medium.
Stick cuttings about three inches deep into the rooting medium and house them three inches aside. Water repeatedly so the media is moist however not drenched.
After round two months, verify to see if the cuttings are well-rooted by gently lifting the slicing out with a device like a pencil or dowel. As soon as they’re rooted, you may transplant them open air.
From Softwood Cuttings
Propagating from softwood cuttings has an excellent greater charge of success than hardwood cuttings.
Not like hardwood cuttings that are already woody, softwood cuttings ought to be extra versatile and fewer inflexible. Take your softwood cuttings in late spring or early summer time.
Put together propagation pots which are six inches deep with holes for drainage. Fill them with a pre-moistened mixture of half perlite and half vermiculite as a rooting medium.
With clear, sharp pruners or a knife, and your gloves on, take four- to six-inch softwood cuttings from the guidelines of wholesome shoots. Take away the leaves from the underside two inches of the slicing, leaving two to 4 leaves on the prime.
Apply rooting hormone to the underside inch or so and stick them into the medium with two nodes buried. Maintain the pots indoors in a vivid location resembling a sunny windowsill.
Water the media repeatedly however don’t permit it to turn out to be waterlogged. Maintain softwood cuttings within the media for one to 2 months earlier than transplanting.
Test that they’re totally rooted by rigorously lifting the slicing out of the pot with a pencil or dowel. When they’re totally rooted, transplant them into the backyard.
The perfect time to transplant your new potted sea buckthorn plant is in early spring. Cuttings might be transplanted once they have developed enough roots.
Dig a gap that’s barely deeper and wider than the unique container. Make sure the soil within the gap is freed from rocks and particles.
Take away the plant from its container and examine it. If the plant is rootbound you’ll have to make shallow, vertical cuts within the ball of soil. Additionally lower two crossing strains on the underside of the basis ball.
Place the plant into the soil so the highest of the basis ball is degree with the floor of the soil. Backfill with soil and pat it down. Water in nicely.
Maintain your new plantings evenly moist however not waterlogged till they’re established.
The way to Develop Sea Buckthorn
There’s no approach round it – sea buckthorn wants full solar to provide these fantastic berries. Though it will probably survive in partial shade, it won’t thrive.
Take it from somebody who has tried to coax fruit out of a sea buckthorn planted in lower than perfect rising situations – it gained’t work! After simply three years of rising in partially shady situations, my sea buckthorn was already struggling a lot that it didn’t make sense to maintain it.
One other requirement is well-draining, loamy soil with a pH of 5.5 to 7.5. Waterlogged soils are unacceptable for sea buckthorn, however the plant can tolerate saline soils.
Don’t permit weeds to invade the realm close to your sea buckthorn because it’s changing into established. Your shrub will profit from mulching with natural matter like compost.
Mulching helps the soil to retain moisture and has the additional advantage of suppressing weeds.
Place two to a few inches of mulch round your shrub all the best way to the dripline – conserving the mulch 4 inches away from the trunk.
Should you take the time to care on your shrub, your sea buckthorn ought to offer you berries for 20 years or extra!
As soon as it’s totally established after one to 2 years, sea buckthorn is drought tolerant.
However if you wish to maximize fruit manufacturing, you’ll want to supply supplemental irrigation, particularly throughout dry spells. Watering with drip or trickle irrigation is good.
You’ll understand it’s time to water when the highest six inches of soil are dry. To verify, use a shovel or an identical device to dig into the highest six inches of soil. If it feels dry as a substitute of moist at this degree, it’s time to water.
Watering deeply however occasionally is healthier than extra frequent, shallow waterings.
Keep away from watering solely across the trunk of your shrub as this could really trigger decay. As a substitute, intention to water the whole floor space of the roots out to the drip line.
This succesful plant has a symbiotic relationship with nitrogen-fixing micro organism so it doesn’t require extra nitrogen and will even be harmed by its utility.
Should you discover new leaves which are smaller than typical, or older leaves which are altering coloration to a darkish blue-green, your shrub could also be poor in phosphorus.
On this case, strive including a fertilizer with solely mineralized phosphorus – not an all objective fertilizer which is able to embody nitrogen as nicely – resembling this one from Arbico Organics.
- Plant in full solar.
- Water repeatedly whereas shrubs have gotten established.
- Mulch to suppress weeds.
Pruning and Upkeep
Pruning is a obligatory activity when rising sea buckthorn. Ensure to put on gloves that can shield your fingers and arms from the thorns.
As these vegetation might be fairly dense, thinning them out permits daylight to penetrate and improves airflow. It additionally encourages fruit to develop on the inside branches.
Usually, feminine vegetation ought to be pruned to keep up a compact form that can make harvesting simpler, whereas male vegetation ought to be left to develop tall to help in wind pollination.
Your general intention when pruning sea buckthorn ought to be to maintain the primary stem and three or 4 branches that develop from the primary stem – these will probably be the place a lot of the berries develop.
Prune off any shoots or suckers that come up from the bottom, in addition to any aspect shoots. Additionally lower off any branches that droop at their ends – these will shade the within branches.
Sea buckthorn ought to be pruned the primary yr of planting, in late winter earlier than the buds start to interrupt. As your shrub ages, intention to prune any wooden that’s six years previous or extra.
If allowed to sucker, sea buckthorn will type dense thickets which is sweet if you wish to develop a windbreak or hedge, however not so good if you would like one neat shrub.
To stop suckers from getting out of hand, you’ll have to comprise them by mowing, or just pulling or pruning them out.
Sea Buckthorn Cultivars to Choose

‘Harvest Moon’ is a Canadian feminine cultivar that produces massive, red-orange berries and a hefty harvest.
It has fewer thorns than the species plant and is straightforward to reap by hand. It’s hardy to Zone 3 and grows as much as 10 toes tall.
A preferred male cultivar is ‘Lord,’ a Russian selection that incorporates few thorns and grows to 10 to 12 toes tall.
It’s hardy to Zone 3 and boasts stunning foliage and fairly flowers in spring which don’t bear fruit. A male is required as a pollenizer for a feminine plant.
Managing Pests and Illness
Happily for us, the listing of bugs and illnesses which have an effect on sea buckthorn is mercifully brief and never often a trigger for critical concern.
Herbivores are one other story, nevertheless, as they might at occasions trigger fairly a bit of harm. Right here’s what to be careful for:
There are a selection of critters which will take pleasure in your sea buckthorn as a lot as you do. Amongst them are birds, deer, rabbits, and rodents.
Deer will flock to sea buckthorn given the prospect. They’ll fortunately feed on foliage and branches in addition to any fruit.
They’ll additionally trample younger plantings. Giving deer another meals supply or utilizing repellents might reduce the issue.
Be taught extra about coping with deer in our information.
Rabbits and Rodents
Rabbits and rodents like subject mice, meadow voles, and pocket gophers will trigger probably the most injury on younger shrubs, established vegetation are often secure.
Use wire or mesh to stop rabbits from chewing new buds and bark. Mice will often do their injury in winter. Pocket gophers are likely to eat sea buckthorn roots.
You may stop these critters from harming your shrubs by conserving any tall grass across the sea buckthorn mowed. In the event that they turn out to be an enormous downside, you may entice these rodents to manage their populations.
There are just a few pests that can go after your sea buckthorn – these embody Japanese beetles and aphids.
These tiny pests are simply an eighth of an inch lengthy with smooth, pear-shaped our bodies that may be inexperienced, yellow, black, brown, or purple.
It’s unusual to search out only one or two aphids – the place there’s one there’ll often be many! They congregate on leaves or stems they usually don’t transfer a lot once you disturb them.
As they go about their enterprise of sap-sucking, they expel a sticky honeydew on the plant leaves which might promote sooty mould that suppresses the plant’s means to photosynthesize.
The excellent news is that reasonable numbers of aphids gained’t injury your sea buckthorn. The unhealthy information is that giant infestations could cause injury and even transmit plant viruses – and these little suckers reproduce shortly.
You’ll know the aphid infestation is massive if you happen to discover yellow leaves and stunted shoots in your shrub.
So what are you able to do? Happily, there are fairly a couple of pure and efficient controls.
Monitor your vegetation, particularly new development, for the presence of aphids so you may stop an enormous inhabitants from forming.
One other preventative measure is to plant flowers that appeal to pure predators like lacewings, hover flies, girl beetles, and parasitic wasps which feed on aphid colonies.
Some choices are Queen Anne’s lace, yarrow, or candy alyssum. I all the time have tons of fascinating trying helpful bugs go to my lovage yearly!
The place aphids are current, spray them with a robust stream of water from your backyard hose to clean them off the plant.
Personally, I don’t thoughts squishing them with my gardening gloves on! An alternative choice is to prune out complete branches which are closely infested.

The pesky Japanese beetle has turn out to be an rising nuisance in North America in recent times and sea buckthorn is on its “to eat” listing.
This metallic brown and inexperienced beetle will munch on the foliage, leaving massive holes. These leaves will ultimately flip brown and fall from the plant.
Managing Japanese beetle populations should be approached in another way relying on the time of yr and stage of the insect’s life.
The adults feed on the leaves, so as soon as the beetles begin flying in the course of summer time, you’ll have to take management.
Eradicating beetles by hand is a tedious – and barely gross! – however efficient technique. Put the beetles you decide in a bucket of soapy water in order that they don’t fly away.
Strive to do that as quickly as you see the beetles and don’t quit – every day elimination will assist you carry on prime of them.
Helpful nematodes can be utilized in late summer time or early fall to handle Japanese beetle populations for the following yr. Nematodes are a sort of roundworm current within the soil.

Sea buckthorn is a strong shrub that isn’t affected by many illnesses. That being stated, verticillium wilt and fusarium wilt can typically be a difficulty.
Verticillium wilt brought on by Verticillium albo-atrum and Verticillium dahliae, or fusarium wilt brought on by Fusarium spp. trigger quite a lot of signs together with yellowing, wilting leaves, and dieback.
The illness exhibits up when shrubs are 5 to eight years previous and it solely takes one or two rising seasons to complete off its sufferer.
Because the pathogens are soilborne, it’s best to destroy affected vegetation and keep away from planting sea buckthorn in the identical location for no less than three to 5 years.
Sea buckthorn will produce an ample annual harvest within the late summer time to fall, relying in your rising zone.
Totally different cultivars produce berries of various colors. Some are yellow when ripe – others orange or purple. Attempt to harvest fruit as quickly as potential as a result of the pores and skin turns into thinner because it ripens.
Since most sea buckthorn vegetation have no less than some thorns, harvesting the fruit might be difficult.
The opposite issue which might make it tough is that the berries wouldn’t have an abscission layer – a layer of cells that causes the fruit to detach when it’s prepared – so even once they’re ripe, they don’t detach simply from the stem.
There are a couple of methods to go about harvesting the berries. If you wish to harvest by hand, grasp a berry, twist it round, and pull it off.
I discovered harvesting berries one by one was simpler than attempting to strip a complete bunch off directly as a result of the fruit has skinny pores and skin and will squish simply – however after all, this takes longer.
I choose to reap sea berries with my naked fingers and attempt to keep away from the thorns. If you wish to play it secure, put on gloves to keep away from being scratched, however it’s possible you’ll discover skinny gloves make the duty simpler than thicker gloves.
One other widespread approach to harvest is by slicing and freezing fruiting branches. That is fairly simple to do since sea berries develop tightly bunched collectively on the branches.
When the berries are ripe, lower off branches with fruit and put them in your freezer. As soon as the fruit has frozen, take away the berries by knocking them off the branches.
The catch with this technique is that it’s best to solely lower a 3rd of the fruiting branches otherwise you danger damaging the plant and a a lot smaller harvest subsequent yr.
Sea buckthorn leaves are additionally filled with antioxidants and nutritional vitamins. You may harvest the leaves any time of yr and dry them to steep for tea.
If you wish to harvest an enormous batch of leaves directly, it’s a good suggestion to make use of the male vegetation since they don’t should put vitality into fruit manufacturing. You can even harvest the leaves from branches throughout pruning.
Contemporary sea berries don’t have a protracted shelf life. It’s best to refrigerate them as quickly as potential after harvest and use them in a single or two days, or freeze them to make use of later.
To freeze, place your berries on a baking tray in a single layer. Freeze them for a couple of hours after which retailer them in a sealed plastic bag or hermetic container.
Recipes and Cooking Concepts
Sea berries really are superfruits – they’re wealthy in nutritional vitamins C, E, and Okay in addition to carotenes, flavonoids, amino acids, and antioxidants.
And though the berries style fairly bitter on their very own, they are often reworked into jelly, jam, sauce, and juice.
One of many first methods I used to be launched to the distinctive citrusy pineapple style of sea berries was by way of a tasty cocktail made with recent juice.
In truth, I typically take pleasure in a non-alcoholic model of this made by merely boiling the frozen berries for 10 minutes, straining the seeds and pulp, and including bubbly water for a refreshing spritzer.
