At the Burchell Nursery, Inc., we have a way with walnuts. We like to think it’s a very innovative way. We strive to provide a range of different rootstocks, including self-rooted clonal varieties and Paradox rootstock. Growers now have a choice of walnut rootstocks to best suit their field conditions.

We know that your orchard is a big investment. Burchell’s innovative rootstocks for walnuts can make the cost of establishing an orchard more affordable and more resistant to known disease for a healthier, more productive, longer lasting orchard. No other California operation gives growers so many options for strong, vigorous and productive walnut trees.

Burchell Nursery provides its customers with the utmost planting flexibility by offering most its varieties as Ready Start® Potted Trees. Please consult with your Healthy Start Trees field representative for current availability and pricing.

Clonal Paradox Rootstocks for Disease Resistance

The Burchell Nursery, Inc. is able to provide our customers with a choice of Paradox rootstocks, compatible with all walnut varieties. Through clonal propagation we can multiply selections of Paradox rootstocks that have shown disease and black line tolerance. One of these, the Vlach rootstock, has proven to be vigorous in orchard test plots throughout the state. It has shown good tolerance to many root infections that commonly plague traditional Paradox seedlings, including crown gall. The VX211 has high vigor and moderate resistance to phytophthora. The RX1 is tolerant to phytophthora.
