Bay bolete (Boletus badius) belongs to the fungi that grow most commonly in Central European forests. It is as widely used in the kitchen as the penny bun and valued for its excellent aroma. It adds flavour to every dish. You may dry it or pickle in vinegar brine. The mushrooms develop single or in groups from middle of summer until autumn. They grow in coniferous and deciduous forests, often on sandy soils on glades and along paths and roads.

The bay bolete mushrooms are medium large. The cap surface takes on a bay or maroon-brown colour, while the tubes at the underside are pale yellow or olive green. The stem is long, brown or pale with brown stripes. Blue-green spots appear on the spots, where mushrooms have been damaged and that distinguishes this species from the cep (porcini). Firm and crunchy flesh has nice mushroom aroma and taste.

The mycorrhizal mycelium of the bay bolete available in our store enables you to grow wood mushrooms in your garden. You should, however, remember, that there are multiple factors that influence the development of fungi that you cannot influence yourself. The soil type, presence of the preferred tree species, with which the mushrooms live in symbiosis and the weather during the vegetation period count among the most important ones.

You may start bay bolete growing from April until late autumn. Choose a site under the trees, such as pines, spruces, oaks and beeches, dig a few holes and place circa 0.5 litre of the spawn mixed with a substrate. The optimal mixture consists of 5 litres of peat, 1 litre of wood coal or ashes, 0.5 litre of gypsum and 0.5 litre of vermiculite. The substrate prepared that way needs to be watered and placed into the holes, covered with a 5 cm thick layer of soil and mulched, so the soil does not dry. You need to water the culture shall the drought period extend over 10-14 days. Provided the conditions would be favourable, the mushrooms may be harvested after 2-3 years already.

There are growing instructions and the sow-by date printed on each package of the mycorrhizal bay bolete mycelium.

Where do our seeds come from?

Exclusion of the middlemen from the whole process not only makes it possible for us to avoid sending out-of-date seeds that might have been lying too long on a warehouse shelf, but also ensures the most attractive price for top quality products.

The quality control process

All our seeds must pass a four-stage quality control process.

Stage one begins with a careful selection of the suppliers. Than we proceed with controlling their crops, foreign producers are not excluded from the quality control process. Plants are checked at every stage of their development: when they start to grow, during blooming and when they start bearing fruit (seeds). At this stage the most important thing is to ensure proper spacing of the plants. Thanks to that obtaining the desired morphological characteristics of each particular species or variety, such as colour, height and shape, can be ensured.

Stage two consists of a detailed verification tests in laboratory conditions. With the use of the highest quality equipment by the highly qualified staff, our suppliers perform more than 30 000 quality checks annually. The seeds that do not meet our requirements are subject to technological refining processes, including drying, cleaning, upgrading and testing again.

Stage three starts with sowing seeds in selected control plots. That way we obtain valuable, exact information concerning their germination that must be maintained at an appropriate level. Simultaneously, the varietal identity of each species is checked at this stage.

Stage four takes place in our warehouses and consists of eliminating seeds that have been stored for too long on our shelves and replacing them with new batches. Each package is stamped with a unique batch number and also with the sow-by-date.

All four stages combined allow us to state with confidence that the seeds we deliver comply with the highest standards and have completed all required control stages with flying colours.
