n1 Tri Voss

No. 1 Tri Voss Citrus Tree is a very hardy citrus hybrid valued as a reliable substitute for lemon. It produces more juice than Yuzu, making it particularly useful for culinary use when acidity and juice quantity are the priority.

The fruit is harvested in September and can be used for juice, sauces, drinks and cooking. Compared with Yuzu, No. 1 Tri Voss is less aromatic, and its zest is not recommended for culinary use, but it offers a better juice yield.

This variety comes from a cross between Poncirus and Citrus papeda, similar in origin to hardy citrus hybrids such as Ivia. It is hardy to around -15°C once established and grown in favourable sheltered conditions.

Our No. 1 Tri Voss trees are grafted onto different citrus rootstocks, including Citrumelo 4475, Poncirus Pomeroy and Poncirus Flying Dragon. These rootstocks influence vigour, cold tolerance, soil adaptation and fruit quality.

For best results, plant No. 1 Tri Voss in a warm, sunny and sheltered position, protected from cold winds. A wall, courtyard or greenhouse-like microclimate can greatly improve winter protection and fruit ripening.

No. 1 Tri Voss can also be grown long-term in a large container, provided it receives regular watering, feeding and winter protection when necessary.
