Information on the 'Armenian' Heirloom Tomato


Heirloom tomatoes can be visually interesting in the garden and add unusual flavors to the dinner table. In most cases, heirloom tomatoes are grown from older genetic stocks that may have become out of fashion with home gardeners. There are many varieties of heirloom tomatoes, one of which is the Armenian heirloom tomato.


The Armenian heirloom is a bicolored yellow and orange tomato that can have red striations in the flesh. Armenian heirloom tomatoes are large; the fruit from this plant grows to between 12 and 20 oz. This tomato plant has an indentation toward the center of the fruit on both the top and bottom.


The Armenian heirloom tomato has sun requirements that are the same as any other variety of tomato. Armenian heirlooms require a minimum of seven hours of sun per day. Planting tomatoes in a location that gets less will result in very good foliage, but lower fruit size and production rates. Tomato production requires a lot of plant energy. Your tomato plants make that energy from sunlight.

Fertilization and Mulch

Your Armenian heirloom tomatoes will benefit from light fertilization throughout the growing season. Use a balanced fertilizer, because it has equal amounts of nitrogen, phosphorous and potassium. Those are indicated on fertilizer packaging as an N-P-K ration. A 10-10-10 fertilizer contains 10 percent of each of these nutrients. Mulching your tomatoes will help keep weeds down and help maintain soil moisture. Using organic mulch, like straw, will also add some organic nutrients to the soil as the mulch breaks down.


Armenian heirloom tomatoes do best in rich, loamy soil that has a high percentage of organic matter. Tomatoes grow best in soils that drain well, however. If your soil is too dense, adding a little sand can help with drainage problems. Do not allow the soil to become soaking wet.


Armenian heirloom tomatoes have problems similar to those of other tomatoes. If the fruit is left in the hot sun for too long after ripening, it can begin to suffer from sunscald and breakdown. Fruit cracking can occur on fruit that is not protected by leaves. The cracks are caused by water droplets drying quickly in the hot sun. They can also be susceptible to powdery mildew, a condition caused by watering in the evening in wet climates.
