GRUBBING UP THE VINEYARD
This spring, we carried out an important but demanding task in our vineyard at Nákle near Ratíškovice – rejuvenating the vineyard. Part of our vineyard – specifically the Grüner Veltliner, Gewürztraminer, Müller Thurgau, and Riesling varieties – had reached the end of their lifecycle. To continue growing top-quality grapes, the time had come to start fresh.
Why is grubbing up necessary?
Vineyards have a limited lifespan – typically 30 to 40 years. Over time, the vines lose vitality, yields decline, and grape quality can deteriorate. Older vines also become more susceptible to diseases such as wood rot or trunk infections. Rejuvenation is essential not only to maintain the quality of the grapes, but also to preserve healthy soil and prepare ideal conditions for future planting.
How does vineyard grubbing work?
Grubbing up a vineyard is more complex than it might seem. First, we remove the trellis wires and cut down the old vines, which are then cleared from the vineyard. Next, we pull out the posts and use a subsoiler to extract the remaining plant material, including root systems.
At this stage, thorough soil preparation is key. Ploughing and loosening the soil improves structure and aeration, removes leftover roots, and helps eliminate pathogens. We also analyze the soil and, where needed, enrich it with nutrients like organic matter or lime to balance pH levels.
Letting the soil rest
Before replanting, the soil needs time to recover. This fallow period usually lasts three to five years. During this time, we plant green manures – such as mustard, vetch, or legume-cereal mixes – to restore fertility and support natural microbial activity in the soil.
Preparing for a new vineyard
After the resting period, we begin planning the new vineyard. We carefully select rootstocks suited to the local conditions and design the layout to ensure optimal sunlight exposure and airflow.
Though grubbing up is labor-intensive and costly, it is essential to securing high-quality grapes for the future. We're already looking forward to planting new rows of Riesling, Müller Thurgau, and Gewürztraminer. With this renewal, we’re investing in the long-term excellence of our vineyards for decades to come.
