General characteristics of a Oleaster

Willow (Olive/ aka Ebbings Sliverberry).

The Olive Willow, or Silverberry, is closely related to the sea buckthorn and is a cultivated species. The Olive Willow is also called silverberry because of its silvery sheen. Its name, "Olive Willow," is somewhat confusing, as it is neither an olive nor a willow. It is a popular plant in permaculture and food forests because it fixes nitrogen underground (food for other plants) and is wind-resistant, making it suitable for creating shelter for more vulnerable species. This shrub originates from East Asia and is also called goumi. The fruits are somewhat tart but delicious in jam, among other things. Allow them to ripen fully. They retain some leaves in mild winters. They can reach a height of about 3 meters. 

The Olive Willow has beautiful gray, leathery leaves. It is one of the few hedge plants that thrives near the sea. The Olive Willow thrives in sea winds and salty soil. 

For a hedge that doesn't necessarily need to be opaque, the Olive Willow is an interesting choice. With this plant in your garden, you'll add a touch of white to autumn thanks to the flowers that appear on the Olive Willow. But perhaps even more striking is the pleasant fragrance these flowers exude. After flowering, red berries appear, which contrast beautifully with the large, silvery-green leaves. The Olive Willow (Ebbingei) will not flower if the hedge is pruned twice a year.

Caring for and pruning your Oleaster

Pruning 

If you want your Olive Willow to become a hedge, it's important to prune it tightly immediately after planting. You can achieve a neat, tidy top by immediately pruning off the top shoots (topping). This will encourage the Olive Willow to also grow new growth at the bottom, creating an evenly full hedge. Longer, protruding branches on the sides can also be pruned immediately, giving the sides a neat, tidy appearance. For a hedge, we recommend pruning your Olive Willow twice a year. It's best to start after the hedge has grown well in May-June, with the second pruning in August. Don't be afraid to prune, but don't prune too deeply. It's better to prune lightly twice a year than to prune very deeply once. If you want fruit on the Olive Willow, we recommend that you do not prune it at all or only prune it once a year in the autumn.

Watering 

During the first year after planting the Olive Willow (Ebbingei), it's important to carefully monitor the soil moisture. The first three months after planting are crucial for its establishment. The Olive Willow needs to develop new roots and can only absorb limited water. Once the Olive Willow hedge has been established for a year, the roots are sufficiently capable of extracting moisture from the soil. It goes without saying that you will need to water it during hot and dry periods.

Where does a Oleaster grow

The Olive Willow thrives in full sun, partial shade, and full shade, and is known for its coastal habitats. It tolerates salty soil and sea breezes well, and grows in any soil type, provided the soil is well-drained.

The plants dislike "wet feet," meaning they sit in a puddle of water for several days. This will cause the roots to rot, and the plant will die. If the soil they will be planted in is sandy (light brown), it is advisable to improve the soil by adding potting soil. This should be done immediately after planting.

This plant prefers moderately nutrient-rich, dry to moist, sandy soil. It is quite tolerant of acidity (pH = 5.5 - 8).

Reproduction rate

1. Very low reproduction rate. The plant hardly spreads, has few seeds or vegetative spread (e.g., trees with heavy seeds).
2. Low reproduction rate. Spread via limited seed production or specific conditions required
3. Average reproduction rate. Regular spread, depending on wind, water, or animals, at a moderate speed (e.g., dandelion).
4. High reproduction rate. Many seeds and multiple spread strategies (wind, birds, vegetative). Quickly colonizes open spaces
5. Very high reproduction rate. Invasive species that spread explosively over large distances (e.g., Japanese knotweed).

Harvest/recognition in winter

The Olive Willow has stiff, leathery leaves. The leaves are dark green on top and gray on the underside. The fruits of the Olive Willow have a silvery sheen. This explains why the Olive Willow is also called the Silverberry.
