What is Vlach Walnut Rootstock?

Developed from Paradox rootstock ( Juglans hindsi × Juglans regia) , Vlach walnut rootstock has a very strong growth ability. Vlach walnut rootstock, which has been used in America since 1990, is resistant to heavy soils. Vlach walnut rootstock, which allows the grafted variety to give larger and more fruit, is also frequently preferred in our country, as it enables the grafted plant to yield earlier. If Vlach walnut rootstock is preferred in regions with suitable climate and soil structure, it provides very positive returns. Vlach walnut rootstock, which has 20% smaller leaf blades compared to RX1 rootstock, is susceptible to nematodes and resistant to root infectious diseases.

What are the characteristics of Vlach Walnut Rootstock?

  • It was developed from the rootstock of Paradox ( Juglans hindsi × Juglans regia) .
  • It shows strong growth.
  • It is highly resistant to heavy soils.
  • It allows the varieties grafted on it to give larger and more fruit.
  • It is susceptible to nematodes and resists root infectious diseases.
  • It has been used in America since 1990.
  • The tree crown volume is 1.5 times smaller than the other paradox rootstocks RX1 and VX211.
  • Compared to the RX1 rootstock, it has 20% smaller leaf blades.

What is Canopy of Vlach Walnut Rootstock?

Vlach walnut rootstock, which has a strong growth rate, differs in tree crown volume compared to classical rootstocks. Vlach walnut rootstock, which has a tree crown volume 1.5 times smaller than other paradox rootstocks RX1 and VX211, stands out with its high yield in terms of fruit quality and size. Less crown volume provides a positive development of fruit quality.

What are the Soil and Climate Conditions of Vlach Walnut Rootstock?

Vlach walnut rootstock can adapt to many different soil types, including heavy textured soils, without any problems. Vlach walnut rootstock, which has been used in the USA since 1990, also provides positive support for strong tree formation. It develops in high and fertile soils due to its high water holding capacity. Suitable for grafting with walnut varieties, Vlach walnut clone rootstock shows strong growth in suitable climatic conditions.

How to Grow for Vlach Walnut Rootstock?

Vlach walnut rootstock is very advantageous in terms of resistance to heavy soils. Although it has 20% smaller leaf blades compared to the RX1 rootstock, this system is quite strong and holds well to the ground.

Species on Vlach walnut rootstock after grafting should be carefully controlled, especially in the first years. In soft ground and windy areas, staking can be done in the first few years.

What are Vlach Walnut Rootstock Grafting Methods?

In order to get high and quality yield from the grafting process of the Vlach walnut clone rootstock, which allows the variety grafted on it to give larger and more fruit, the grafting process should be carried out at the right time and with the right grafting methods. In the production of seedlings using clonal walnut rootstocks, T budding or chip budding is mostly used.
