How to Grow Sea Buckthorn from Seed: A Comprehensive Guide

Unlocking the Power of Sea Buckthorn: A Step-by-Step Guide

Sea buckthorn (hippophae rhamnoides), a hardy and versatile plant, is gaining popularity for its numerous health benefits and vibrant, nutritious berries. This article will provide a comprehensive guide on how to grow sea buckthorn, covering everything from seed propagation to choosing the right varieties for your needs. Whether you’re a seasoned gardener or a beginner, learning how to grow sea buckthorn will be an exciting addition to your garden.

Sea Buckthorn Varieties

Before diving into how to grow sea buckthorn, it’s essential to familiarize yourself with the different varieties available. Sea buckthorn (Hippophae rhamnoides) is a deciduous shrub that belongs to the Elaeagnaceae family. There are several sea buckthorn varieties, each with unique characteristics:

  1. Wild Sea Buckthorn: A hardy, adaptable shrub that thrives in various climates and soil types. It can be found in coastal areas, mountains, and even semi-desert regions. If you’re interested in cultivating wild sea buckthorn, be prepared to manage its vigorous growth, as it can spread quickly through suckers and seeds.
  2. Hippophae rhamnoides ‘Leikora’: A popular cultivar known for its large, bright orange berries and excellent resistance to pests and diseases.
  3. Hippophae rhamnoides ‘Russian Orange’: This variety boasts abundant fruit production and is often used for commercial cultivation.
  4. Hippophae rhamnoides ‘Silver Star’: A smaller, more compact variety, ideal for growing in containers or small gardens.

When selecting a sea buckthorn variety, consider your climate, available space, and desired berry production.

Encountering Wild Sea Buckthorn

Wild sea buckthorn can be found throughout Europe and Asia, often thriving in harsh conditions like coastal and mountainous regions. This resilient plant provides food and shelter for various wildlife species, while its extensive root system helps prevent soil erosion.

Growing wild sea buckthorn in your garden is an excellent way to create a natural, low-maintenance landscape that benefits the environment. However, remember that wild varieties may produce smaller berries and be less resistant to diseases than cultivated varieties.

How to Grow Sea Buckthorn from Seed

Growing sea buckthorn from seed can be a rewarding experience, but it requires patience and the right conditions. Follow these steps to germinate sea buckthorn seeds successfully:

  1. Seed collection: Harvest sea buckthorn berries in the fall, then remove and clean the seeds. If you don’t have access to fresh berries, purchase seeds from a reputable supplier.
  2. Stratification: Sea buckthorn seeds require cold stratification to germinate. Place the seeds in a moistened, sterile medium (like a mix of peat moss and sand) and store them in a sealed container in the refrigerator for 60 to 90 days.
  3. Sowing: After stratification, sow the seeds in a well-draining potting mix, covering them with a thin layer of soil. Keep the soil consistently moist but not waterlogged.
  4. Germination: Place the seed tray or pots in a bright location with a temperature of 68-72°F (20-22°C). Sea buckthorn seeds can take anywhere from 30 to 60 days to germinate. 5. Transplanting: Once the seedlings have developed at least two sets of true leaves, transplant them into individual pots. Continue growing the seedlings in a bright, sheltered location until they are large enough to be planted outdoors.

How to Propagate Sea Buckthorn

Apart from growing sea buckthorn from seed, you can also propagate this plant using other methods, such as hardwood cuttings and layering. Here’s how to propagate sea buckthorn using these techniques:

  1. Hardwood cuttings: Take 8-12 inch (20-30 cm) long cuttings from healthy, mature sea buckthorn plants in late winter. Make sure the cuttings have at least 3-4 buds. Dip the bottom end of the cuttings in rooting hormone, then plant them in a well-draining potting mix. Keep the cuttings in a sheltered, frost-free location and maintain consistent moisture. Roots should develop within a few months.
  2. Layering: Layering involves bending a low-growing branch of a sea buckthorn plant to the ground, partially burying it in soil, and allowing it to develop roots. Once the new roots have formed, you can sever the connection to the parent plant and transplant the new plant to another location.

Planting Sea Buckthorn

After you’ve propagated sea buckthorn using seeds or other methods, it’s time to plant it in your garden. Follow these steps for the best results:

  1. Site selection: Choose a location with well-draining soil and full sun exposure. Sea buckthorn can tolerate partial shade but produce fewer berries in these conditions. Ensure the site has enough space for the mature plant, taking into account its height and spread. 2. Soil preparation: Amend the planting site with organic matter, such as well-rotted compost, to improve soil fertility and drainage. Sea buckthorn prefers a neutral to slightly alkaline soil pH (6.0-7.5).
  2. Planting: Dig a hole twice the size of the root ball, ensuring it’s deep enough to accommodate the plant’s roots. Place the sea buckthorn in the hole, ensuring the root collar is at the soil surface. Backfill the hole with the excavated soil and gently firm it around the roots to eliminate air pockets.
  3. Watering: Water the newly planted sea buckthorn thoroughly, and continue to water regularly during the first year of growth. As the plant establishes, you can reduce watering frequency, as sea buckthorn is relatively drought-tolerant.
  4. Fertilizing: Following the manufacturer’s recommendations, apply a balanced, slow-release fertilizer in the spring. Sea buckthorn doesn’t require heavy fertilization but will benefit from an annual application to support healthy growth and fruit production.

Harvesting Sea Buckthorn Berries

Sea buckthorn berries, rich in vitamins, minerals, and antioxidants, are the highlight of growing this versatile plant. To harvest sea buckthorn berries, follow these tips:

  1. Timing: Sea buckthorn berries are typically ready for harvest in late summer or early fall, depending on the
  2. variety. Berries should be plump, bright in colour, and slightly soft to the touch. Remember that sea buckthorn may not produce a significant harvest until 3-4 years after planting. 2. Method: Sea buckthorn berries are delicate and can be easily damaged during harvesting. Use pruning shears to clip small clusters of berries from the branches, taking care not to damage the plant. You can also use a berry rake or comb to separate the berries from the branches gently.
  3. Preservation: Fresh sea buckthorn berries have a short shelf life and should be used or processed within a few days of harvest. They can make juice, jams, sauces, or even skincare products. To store sea buckthorn berries for longer periods, freeze them in a single layer on a baking sheet before transferring them to an airtight container.

Sea Buckthorn Care

Your sea buckthorn plants can thrive and produce abundant harvests for years with proper care. Follow these guidelines to maintain the health and productivity of your sea buckthorn:

  1. Pruning: Regular pruning promotes healthy growth and helps control the size of the plant. Remove dead, damaged, or overcrowded branches in late winter or early spring. Also, prune out any suckers growing from the base of the plant to prevent it from becoming too dense.
  2. Pest and disease control: Sea buckthorn is relatively resistant to pests and diseases. However, look for aphids, spider mites, and scale insects, and treat any infestations promptly. Diseases such as powdery mildew and rust can be prevented by ensuring proper air circulation and avoiding excessive moisture on the foliage.
  3. Pollination: To ensure a bountiful harvest, having both male and female sea buckthorn plants in your garden is crucial. Male plants provide the necessary pollen for female plants to produce berries. Plant at least one male for every four to six female plants, and choose compatible pollinator varieties for the best results. Some common male varieties include ‘Pollmix’ and ‘He-Poll.’
  4. Winter protection: While sea buckthorn is cold-hardy, protecting young plants and those grown in containers from harsh winter conditions is essential. Mulch around the base of the plant to insulate the roots, and wrap container-grown plants in burlap or frost cloth to prevent damage from freezing temperatures.
