Know-How starts with the seeds

 

Quality and guarantee of origin are laying the foundation for further success, because the genetic properties are enormously important for the growing plant.

 

 

That’s why our seeds are mainly harvested by ourselves and we prepare them in-house. Our long-standing experience about origin, preparation and storage ensures the high quality of our products. 

 

 

Our know-how for your success!

Harvesting

Guaranteed origin is highest priority

We always strive to provide the appropriate seeds for your area. Under “Interesting Facts” you can inform yourself as to which origin is the best for your growing area.

 

The main part of the harvesting of forest tree species in Austria is carried out by ourselves. Thus, for example, maple and fir are picked with the aid of tree climbers in authorized harvesting stands.

 

For tree species that are located in distant countries such as: China (Japanese maple) and the USA (Blue spruce) we get our supply through good contacts and from long-term business partners.

 

A sensitive subject is the origin guarantee of the Nordmann fir, which grows in the regions of Georgia and Russia. Because of the long-term cooperation with local partners, we can guarantee the supply from the correct provenances. All our planting material is of course also part of this guarantee. We are very pleased to have secured the harvesting rights in the areas of Ambrolauri-Tlugi and Borshomi-Bakuriani in Georgia for the next 10 years in a crop licence auction.

Preparation

Handling with care is the foundation for quality

The quality of the harvested seeds must also be guaranteed in further processing. After the harvest, the seeds of the corresponding tree species are cleaned, dried and mechanically extracted from the cones or pulp. Afterwards, the ready prepared seeds are stored in canisters and drums in three special cooling rooms with different temperatures. The storage life of seeds varies a lot from one year (eg: Norway maple) up to 10 and more years (eg spruce and larch) if stored properly.

 

The timely shipment of the seeds to our customers takes place according to the quantity, either by freight on pallets or via delivery service in cartons. The seeds are securely sealed in foil and labeled with the respective names. As a special service we offer ready-made stratified seeds, which are delivered at the desired sowing time. This means you need make no further effort and you can sow the seeds immediately after receipt.

Sowing

Each tree species has its own rhythm

Therefore we unfortunately cannot provide a standard sowing manual. Some tree species need a stratification process to germinate in spring. These tree species are specially marked in our assortment list. We can supply them ready for you at the right sowing time.

 

Some trees such as oak, walnut, maple and cherry are mainly sown in autumn. While they are sheltered in the ground during the winter, the anti-sprouting effect is naturally reduced. This process is called natural stratification. This process is only successful when the seeds are left alone in winter and are not disturbed by rodents for example.

 

All other tree species are usually sown in spring, between March and May, in the open field, then covered and slightly pressed with some soil or sterile sand (about 3 times the thickness of the seed size).

Recultivation

Trees and shrubs are also very successfully used for the recultivation of slag heaps, road embankments and landslide areas.

 

Various application methods are used in this instance. On steep slopes with lack of humus the tree seeds are applied together with grass seeds by the hydroseeding method. The thick-film technology, which was developed by Dr. Roman Schaffer from Irdning significantly improved the germination results and biomass formation. With this hydroseeding method the greening results are showing more quickly and are more sustainable. The effects of unfavourable boundary conditions such as exposure, steepness, humus and nutrient deficiency are significantly reduced.

 

For this ​​method, easy-seeding pioneer tree species such as birch and white alder are particularly suitable. But even small-grained shrubs like wild roses and conifer seeds can be used quite well for this purpose.

 

In an easy accessible terrain, tree seeds can of course also be applied in the conventional way. The most favourable time for this is late autumn, just before snowfall, or you can also choose to sow on snow in late winter. In this instance the natural processes of water absorption / seed swelling / sprout control can act freely. And losses by natural predators are also largely minimized.

 

Sowing has proved particularly successful under the protection of coconut mats. This 100% biodegradable coconut fabric is used for slope stabilisation and ensures a 1.5-fold moisture absorption. Additionally it supports the collection of foliage and fine soil. This has a positive impact on the covering of the seed and the formation of a good sprouting bed. Practice has shown that a much better sprouting rate is obtained through the use of coconut mats than without.
