The brandywine tomato plant is one of the most popular heirloom variety tomatoes. It produces large-leaved foliage with large beefsteak-sized fruit. This variety of tomato is late producing with the fruit appearing 90 to 100 days after seed planting. Brandywine tomato plants first appeared in 1886 and regained popularity in 1982 along with other heirloom plants. Brandywine tomato plants are grown the same as other tomato varieties; however, they tend to grow taller with large fruit that requires additional support.
Prepare a garden planting location by tilling the soil to a depth of 6 to 10 inches. Remove all weed and other vegetative growth from the area. Water the soil well and apply a balanced starter fertilizer.
Plant the tomato seedlings slightly deeper than they were growing in the container. This will force the plant to produce additional roots to create a strong structure. Space the plants 15 inches apart in rows that are 3 to 4 feet apart.
Water the soil well after planting to a depth of several inches. Continue to water the plants so the soil remains moist through the growing season. It is better to give the tomatoes several heavy water applications per week instead of daily light watering as these cause the roots to stay close to the soil surface.
Place mulch around the plants once the soil has warmed up to control weed growth and increase air circulation and moisture retention. Applying black or red plastic sheeting or dried grass clippings are good choices.
Support the brandywine tomato plants with a trellis or several stakes with twine wrapped around. This will support the large branches and heavy fruit to prevent damage.
Apply a high phosphorus and potassium fertilizer every other week once the tomato blossoms have appeared. Limit the amount of nitrogen applied as this will stimulate foliage growth instead of fruit growth.
