Heirloom Marriage™ Genuwine is an indeterminate red slicer tomato with deeply ribbed fruit and a rich, balanced flavor.

The upright plant keeps growing and setting fruit through the season, so it needs room and reliable support. Its red slicers work well fresh in sandwiches and salads. ## Growing conditions Choose full sun and moist, well-drained loamy soil with a slightly acidic reaction. The breeder recommends in-ground culture. Steady watering helps reduce fruit splitting and blossom-end rot, while excess nitrogen can produce leafy growth with fewer tomatoes. ## Maintenance Transplant after frost danger has passed. Install a sturdy cage or trellis while the plant is young, water consistently at the soil line, and pick mature fruit regularly. The source maturity range is counted from transplant and can vary with weather and growing conditions.
