Yellow Brandywine Heirloom Tomato

10 Seeds

Yellow Brandywine Heirloom Tomato is a prized heirloom variety known for its large, golden-yellow beefsteak fruits, rich sweet flavor, and creamy texture with low acidity. Fruits typically weigh 300–600 g, with some exceeding 800 g under ideal growing conditions. They are excellent for fresh slicing, salads, sandwiches, gourmet dishes, roasting, and juicing. This vigorous indeterminate variety produces fruit continuously throughout the growing season and performs exceptionally well in the Gulf region when planted during the cooler months. It is suitable for gardens, greenhouses, raised beds, large containers, and hydroponic systems.

• Fertilize every 2 weeks with a balanced fertilizer during vegetative growth, then switch to one higher in potassium and phosphorus during flowering and fruiting.
• Apply organic mulch to conserve moisture and keep the root zone cool.
• Yellow Brandywine Heirloom Tomato performs exceptionally well in greenhouses, hydroponic systems, raised beds, and large containers.
