Characteristics of Citrullus lanatus 'Janosik'

'Janosik' produces medium-sized, round to slightly oval fruits that typically weigh between 3 and 5 kg. The rind is dark green with light stripes, giving the melon its classic watermelon appearance.

Growing conditions:

• Sun: Full sun is essential for maximum sweetness and good fruit set.
