The Burpee company is known as the seed company that provides tomato plants for gardeners who want to grow them big. With two of their most popular tomato plants called the Burpee Big Boy and Burpee Big Beef, you know before you even get the plants into the ground that any tomatoes they produce are going to be bigger and better than any others around.
Purchase the tomato plants. Burpee has several varieties of tomato plants that are known for producing big tomatoes. Look for names such as Big Boy, Big Beef, Big Beefsteak and Big Girl. Choose plants with sturdy stems that are 6 to 8 inches tall and appear healthy and green.
Select an area for planting. Big Burpee tomato plants prefer well-drained soil and require at least six hours of sunlight per day. When possible, prepare the soil a few weeks ahead of time by adding compost or leaves into the top layers of the soil.
Dig holes 3 to 4 inches deep with 4 to 5 feet of spacing to allow for cages or stakes to be added as plants begin to grow. Fill the holes with water before adding the plants. Bury the tomato plants slightly deeper than the pots they were in and return loose soil to the hole. Lightly pack the soil around the stem and water thoroughly.
Add mulch around the plants. Place a 2- to 3-inch layer of compost or leaves around the big Burpee tomato plants to help them conserve water and keep weeds from growing.
Stake or cage the Burpee tomato plants. Once tomato plants have become established, add stakes or cages to help support the growing plants. Secure them to the stake or cage with garden ties to help keep them supported, but keep the tie loose for adjustments as they grow.
Remove suckers and side shoots. Prune small shoots near leaves where they grow from the stems. Many tomato growers consider this the ultimate trick to getting plants to grow taller and the tomatoes bigger.
