Walnut tree (Juglans regia) Mars

Juglans regia 'Mars' is a variety originating in the former Czechoslovakia, known for its high fertility and frost resistance. This variety is characterised by high quality fruit, compact growth and easy cultivation.

Mars' fruits are large, oval, with a thin shell which separates easily from the core. The kernels are sweet, without bitterness, and suitable for direct consumption and processing. They ripen in late September to early October, making them one of the later ripening varieties.

The 'Mars' tree has medium vigorous growth and produces a spreading, spherical crown. Its late flowering significantly reduces the risk of damage from spring frosts. Trees begin fruiting relatively soon after planting and produce high, regular yields. The variety is highly hardy and has good disease resistance, minimising the need for chemical control.

This variety is grown on the seedling rootstock of the royal walnut (Juglans regia). Seedling rootstocks ensure vigorous growth and longevity of the tree, and are ideal for deep, fertile soils with adequate moisture. Trees on this rootstock can reach larger sizes, so it is important to give them sufficient room to grow.

A sunny site sheltered from strong winds is best suited for growing 'Mars'. The trees require deep, fertile and well-drained soils with a neutral to slightly alkaline pH. Regular pruning is not necessary, but removal of damaged or diseased branches is recommended. Planting is best done in spring or autumn, and it is important to ensure sufficient space for a vigorous root system.

The 'Mars' walnut is an ideal choice for commercial growing and for gardeners looking for a reliable variety with good quality fruit, high yields and ease of care. Its hardiness and disease resistance make it suitable for areas with more difficult climatic conditions.
