Companion Plants

Basil, oregano, marjoram, carrots, cucumber, peas, pole beans, and annual flowers all make excellent companions for beefsteak tomatoes.

Growing conditions

Beefsteak tomatoes grow best when the soil is warm -65-90°F. All tomatoes appreciate nutrient-rich soil, so plan to amend the soil with aged compost or manure before planting seeds or transplant seedlings. Soil should be well-drained but still hold some moisture. A layer of mulch helps prevent the roots from drying out from evaporation. The soil must be consistently moist, or the fruit will split. Compost tea that is high in phosphorus is an excellent way to fertilize once fruit begins to set.

TIP: Mulch is an excellent tool to help prevent water evaporation and to fight weeds.


Beefsteak tomatoes are heavy feeders and will deplete the soil, as do most varieties of tomatoes. Rotate them each year or amend the ground where you grow them. Doing so will help to curb blossom end rot and avoid pest issues.

Anticipated yields

Plan your garden yield at 3-4 plants per person. Expect tomatoes in the 1-2 pound range, and each plant should yield 10-80 pounds of tomatoes per plant.


Beefsteak tomatoes are an award-winning slicing tomato. They are excellent for fresh consumption and are lovely eaten fresh off the vine or in sandwiches, salsa, salads, and just plain with salt. Their acidic flavor and their large size are ideal for sauces and salsas.
