Sea buckthorn in the garden: tips on care and cultivation

How and where can you grow sea buckthorn plants in the garden? What do you have to consider when cutting sea buckthorn? We give tips on care and reveal how the fruit can be used as sea buckthorn juice, oil and liqueur.

Sea buckthorn (Hippophae rhamnoides) in your own garden? A few years ago the plant was still considered a real exotic, but now the orange-glowing bushes have become a real trend among hobby gardeners. Rightly so - because sea buckthorn is not only a real eye-catcher in every garden, its healthy fruits are also a real superfood and can be used in a variety of ways. Here we will tell you how you can achieve high yields over many years, what care measures are necessary and what the fruits of the sea buckthorn can be used for.

Sea buckthorn: origin and characteristics

The sea buckthorn originally comes mainly from Nepal. From here it spread over the entire Caucasus to China, Canada and Scandinavia. During the first Ice Age, the plant came to Central Europe from Central Asia, so that today it is also considered to be native to Germany. Today the sea buckthorn is the most important representative of the olive family (Elaeagnaceae).

By the way: Its Latin name can be translated as "shiny horse" - because the sea buckthorn was actually over For centuries it was mainly used as a medicinal plant for animals and was used in particular in the grooming of horses Mission.

Against the background of the diverse uses of sea buckthorn as food, it was in Germany, however, has only been cultivated and deliberately large-scale in the GDR since the late 1960s cultivated. Today, China is the international pioneer in sea buckthorn cultivation, while France has taken the lead in Europe. A confrontation with this extraordinary plant is not uncommon, especially in the French Alps Finally, as they make their way into all shops for French specialties via regional processing finds. In addition to the bright orange-red and oval-shaped fruits, which are numerous the branches of the bushes up to six meters high adorn the sea buckthorn can also be recognized by its narrow, gray-green and white-silvery hairy leaves, which are arranged alternately are. On the other hand, the small green-brown flowers that bloom in spring between March and May on the shoots from the previous year are relatively inconspicuous. The sea buckthorn is also dioecious, which means that either only male or female flowers sit on a plant. For this reason, the female plants can only bear fruit if they have previously been pollinated by a male partner in the immediate vicinity.

The best species and varieties of sea buckthorn

In addition to the wild sea buckthorn, there is now a selection of cultivated forms that are particularly suitable for growing in the garden. In the gardening trade, a distinction is often made between male and female cultivated forms, with only the female later developing the distinctive orange-red fruits. Here is an overview of the best types of sea buckthorn to grow in the garden.

Female sea buckthorn varieties

The most common in the garden are female sea buckthorn plants, as they are the only ones to develop the orange fruits, which can be harvested from August to the end of September. The female sea buckthorn plants also show inconspicuous greenish-brown flowers from March to April. The most popular fruiting sea buckthorn varieties in the garden include:

"Askola":

• Vigorous variety that can reach heights of up to 5 m without pruning
• Good regeneration after pruning, but risk of wind breakage
• Very dense fruit set with deep orange, sweet and sour fruits
• Moderate thorns

"Frugana":

• Strong, upright growth up to 4 m in height
• Strong regeneration after pruning, but risk of wind breakage
• Early variety with fruit ripening from the beginning of August
• Lots of shiny orange fruits; Juice mild in taste
• Little branching and thorns

'Hergo':

• Medium, upright and well branched growth; Slightly overhanging with heavy curtains
• Very good regeneration after pruning; particularly weatherproof
• Particularly productive; light orange, color unstable fruits
• A quick harvest is necessary, otherwise the fruit will go rancid

‘Leikora’:

• Strong, compact and broadly upright habit
• Good regeneration after pruning
• Late variety with fruit ripening from the beginning of September to the end of October
• Dark orange, droplet-shaped fruits
• Vitamin C degradation is particularly slow after harvest 

Male sea buckthorn varieties

If you are not only planting sea buckthorn for aesthetic reasons, but also want to enjoy the fruit, it is essential to also establish a male sea buckthorn in your garden. Only in this way can the female sea buckthorn plants be pollinated and develop their fruits. In the gardening trade, the male cultivated form of the sea buckthorn is mostly marketed under the name ‘Pollmix’. These are other varieties that were bred for high pollen production. They are differentiated depending on the time of flowering:

'Pollmix'

• Male sea buckthorn cultivated form, therefore does not produce any fruit
• Brown-orange flowers
• Valuable pollen donor
• Very hardy
• A total of four different types, which differ in terms of the start of flowering
  1. ‘Pollmix 1’: Early flowering, almost thornless
  2. ‘Pollmix 2’: Mid-early flowering, heavily thorny
  3. ‘Pollmix 3’: Mid-early to late flowering, weakly thorny
  4. ‘Pollmix 4’: Mid-early flowering, little thorn

Growing sea buckthorn tree in the garden

Sea buckthorn is becoming increasingly popular. No wonder that more and more gardeners want their own sea buckthorn bush. Fortunately, growing sea buckthorn in the garden is relatively straightforward if you know what to look for.

Planting sea buckthorn in the garden

The best time to plant sea buckthorn in the garden is between October and November or the end of February. Sea buckthorn prefers airy, sandy soils that have a slightly acidic to basic environment and are not too rich in nutrients. Heavy soils should be mixed with at least a third of sand. The lighter the soil, the less is needed here. If, on the other hand, the soil is sandy, mixing in potting soil can promote higher yields. The best way to do this is to use compost that contains a lot of phosphorus but not too much nitrogen. So ours would be best suited Plantura organic potting soilwhose natural phosphorus release promotes good root growth and supports the formation of flowers and fruits. Very sandy soils are best mixed with such a suitable potting soil in a ratio of 1: 1. The sea buckthorn also needs a lot of light. A very sunny location without shade from other trees is therefore perfect.

Sea buckthorn is known for its broad, bulky growth. Ideally, it should therefore be planted so that it has at least three meters of space on both sides to expand. In addition, gardeners who dream of a sea buckthorn should know that the plant forms runners and can thus spread across the garden. To keep the spread in check, the use of a root barrier and the regular removal of cuttings can be useful measures.

Tip: As already mentioned, the sea buckthorn is dioecious, which is why you should always plant female varieties together with a male variety. A male plant can usually pollinate at least four to five female plants - more depending on the variety. Ideally, the male plant should be oriented in the wind direction to the other female sea buckthorn plants. Alternatively, sea buckthorn is now also available as a self-fertilizer, such as the ‘Friesdorfer Orange’ variety, but the yields are usually lower.

Plant sea buckthorn in the bucket

Sea buckthorn can also survive in the bucket for a few years, but needs enough space here too. The bucket for the sea buckthorn should be at least 60 centimeters wide. Ideally, buckthorn plants in the tub should be repotted regularly into larger containers. It is also recommended to use a citrus plant soil, which is mixed with about a third of sand and unbroken expanded clay. Special attention must be paid to the sea buckthorn in the bucket when caring for it: Because the pot volume and thus also the capacity of nutrients is limited, it is advisable to fertilize the sea buckthorn every now and then with something like that liquid Plantura organic citrus and mediteranean fertilizer to supply. It is also worth repotting the sea buckthorn in the pot regularly every few years and then treating it to new soil and a solid organic flower fertilizer with a high phosphorus content. In general, however, the plant thrives better and less complicated in the soil.

Maintain sea buckthorn

As a rule, sea buckthorn in the garden is considered to be extremely robust and easy to care for. However, in order for the plant to thrive, it should be given a little attention every now and then and a little care.

Water and fertilize sea buckthorn

Sea buckthorn in the garden is one heat resistant plant and extremely drought-resistant, which is why the watering can and garden hose can safely be put aside - the only exception: sea buckthorn in the bucket must be under In certain circumstances, for example in very hot summers, additional watering is required, as there is less substrate available and the soil in the pot faster dries up. Waterlogging, on the other hand, should be avoided as the sea buckthorn is sensitive to it. The plant is just as undemanding as watering when it comes to the supply of nutrients, because the sea buckthorn largely self-fertilizes. It covers its nitrogen requirement through the symbiosis with nodule bacteria in the root space. Only in the first few years does this process not work smoothly, which is why fertilization is recommended. The use of good potting soil is sufficient for this, or you can use an organic slow release fertilizer such as ours Plantura organic flower fertilizer or a small amount compost.
On the other hand, sea buckthorn in the bucket should be fertilized a little more often, as it has a limited soil volume with nutrients available. If you can't work the organic fertilizer well into the surface, then soak it simply soak it in water for a few hours, stir and then pour the fertilizer into the Pot. Finally, the whole thing should be covered with a thin layer of bark mulch.

Cut sea buckthorn

Regular pruning of sea buckthorn in the garden is essential in order to be able to harvest productively every year. With a harvest including the shoots, an additional cut is of course unnecessary. Newly grown shoots should generally not be shortened, because the shoots from the previous year always bear the fruit.

If the fruits are not harvested together with the shoots, a cut should be made every two years from the second year in late winter. The harvested shoots are cut back to short beginnings. In the case of particularly vigorous varieties, the sea buckthorn can also be thinned out a little. Male strains can even be grown for three to four years without pruning. Even then, only a maximum of half of the shoots should be cut so that sufficient pollen is available for the fertilization of the female varieties in the next season. Bushes that are too dense can also be thinned out and dead branches removed all year round. This ensures that the innermost bushes are always supplied with sufficient light. As during the harvest, you should protect yourself from injury by wearing gloves when cutting.
Tip: If you have two or more female plants, cut them alternately every year - this will maximize your yield!

Summary - How to cut sea buckthorn:

• wear gloves
• Cut in late winter before flowering begins
• Cut female varieties every 2 years, male varieties every 3 - 4 years
• Cut old shoots back to the roots, young shoots are not cut
• Cut cautiously on male plants, also leave old wood standing
• Clear out all year round as required

Hibernate sea buckthorn

Sea buckthorn is prepared for all climatic conditions and is usually hardy down to - 43 ° C. However, young plants should still spend their first winter in the greenhouse before they are planted outside.

Propagate sea buckthorn

Propagating sea buckthorn is child's play - in fact, it is usually more of a problem to limit the reproduction of sea buckthorn in the garden. Thanks to its foothills, it will spread very quickly on its own and form dense hedges if you don't take countermeasures.
However, if you want to specifically raise the next generation, there are various options for doing this. The simplest option is to use the foothills. This can either simply continue to grow at its location, if this corresponds to the desired location. However, if you prefer to locate the plants in a different part of the garden, you can use the rooted ones Cut off offshoots together with the longest possible piece of root and re-create them at the desired location in the garden plant.

Another method of sea buckthorn propagation is subsidence. A shoot that grows near the ground and on the outer edge of the sea buckthorn can be used as a sinker. Now a narrow furrow is dug, in which the selected shoot is placed and covered with earth. Only the tip of the shoot should look out of the earth at the end. In the case of shoots that are under tension, it can also be helpful to weigh the whole thing down with stones - but the shoot should not break off under any circumstances. In the sunken section, roots gradually form, so that an independent plant emerges. As with the runners, this can either remain at its location or be cut off in the following year and planted at its new destination.

You can also use cuttings for growing new plants with the sea buckthorn. For this purpose, about 15 to 20 centimeters long center pieces are cut from the shoots of the sea buckthorn in winter. Strong shoots from last year are best suited for this. The cuttings should be at least two nodes long. Now it is put into a pot with loose, nutrient-poor potting soil so that only the upper third peeps out. Our Plantura organic herb & seed compost you can use it very well for this. In order to increase the air permeability and the success of rooting, it is advisable to mix 30% sand into the potting soil. In the near future, the cuttings should be in a cool (but frost-free), shady place protected from the wind. The pot must never dry out completely, but waterlogging should be avoided. After the cuttings have started to sprout, you have to wait about three weeks before you can plant the sea buckthorn in a suitable spot in your garden.

Tip: Propagation by cuttings is considered to be more demanding than that by runners or dips. Since plants usually do not actually grow from all cuttings, it is advisable to use several cuttings at the same time if you want to grow a plant.

Summary - this is how you propagate sea buckthorn from cuttings

1. Cut off cuttings (15-20 cm long central parts of a shoot with at least two leaf nodes) in winter
2. Plant cuttings in a pot with potting soil so that only a third is visible
3. Set up in a windless, cool and shady place.
4. Keep moist, but avoid waterlogging.
5. Plant out in the garden about three weeks after the cuttings have been driven out

Is Sea Buckthorn Poisonous?

The sea buckthorn with its thorn-covered branches may have a deterrent effect, but neither fruits, leaves nor flowers are poisonous. On the contrary: the berries are considered to be extremely healthy, taste extremely tasty and can be consumed in any quantity without hesitation.

Anyone who already suspects that harvesting the tasty fruits through the thorns will not be child's play is unfortunately lying Correct: To avoid injuries, gardeners should therefore not open the berries without protection from them Harvesting gloves. Many also use a fork or a berry comb to help push the berries off the branches.

The later the harvest, the better the chances are that the berries can simply be shaken off the branches and caught with a cloth. How firmly the berries sit on the shoots varies from variety to variety. It is also common practice to cut whole branches into small pieces and then shock freeze them so that you can shake off the berries afterwards.

Use the healthy sea buckthorn fruit in the kitchen

The sweet and sour taste as well as their high content of vitamins (C, E and B12) and beta-carotene make the fruits of the sea buckthorn a real regional superfood.
