A big slicer any gardener can enjoy growing is the beefsteak tomato. With the right care, a single beefsteak tomato can weigh as much as one to two pounds. The key is that the tomato plant which provides such large tomatoes will need support, fertilizer, and plenty of water to produce such a succulent fruit. To care for beefsteak tomato plants you'll want to tend to your plants regularly and harvest ripe tomatoes as soon as they are ready.
Loosen the soil in the bed where you want to plant your tomatoes. This needs to be in a full sun area with soil that drains well rather than holding puddles of water. Add 3 to 4 inches of compost or garden soil over the bed and mix it with the bed to an even consistency.
Dig a hole for each seedling you have which is slightly larger than the pot the seedlings are in. Space the holes 3 feet apart. Put a seedling into each hole and lightly press the soil in around the root ball.
Water the seedlings well to moisten the soil around each plant and don't let the soil dry out during the first month. As new growth appears you can start watering deeper but still continue to water as often as needed to keep the soil moist.
Place a tomato cage around each seedling. As the plant grows, be sure to help the plant hold the support, using plant ties as needed, to secure the main stem of the plant to the cage.
Apply fertilizer to the plant according to the packaging directions as frequently as possible. When you see fruiting start, stop fertilizing for the season, otherwise you'll have an excess of foliage, not large tomatoes.
Weed the bed weekly and anytime you see weeds starting to grow in the soil. Run the cultivator over the soil a few times to loosen the upper surface, but be sure to avoid disturbing the roots of the tomato plants.
