Tomato plants vine like crazy in my garden. is it a soil imbalance?

No, that's what tomato plants do. In nature they are laying on the ground growing in every direction. It shows you have very healthy plants.

You can buy select varieties that vine less / are more bushy (dwarf).

Agree with @SedonaDebbie- tomatoes are a sprawling vine rooting all along the stems in the wild- but:

As @sallyg said, your choice of tomato variety is a big factor- as their vining growth habits differ.

Determinate tomato varieties vine less than indeterminate varieties.

Bonnie Plants said:

Determinate varieties (including bush varieties) reach a certain plant height and then stop growing.

Indeterminate varieties continue to grow and produce tomatoes all along the stems throughout the growing season. Indeterminate plants need extra-tall supports of at least 5 feet.

You may have seen photos of 10- or 15-foot tomato vines. These are definitely indeterminate types.

Think of it like this:
Indeterminate = their vining will continue until killed by frost or you.

Welcome to NGA @Laceydog2

What varieties of tomatoes (that is, the name of the plant, such as "Celebrity" or "Big Boy") are you growing? Are they getting plenty of light? Some varieties do naturally grow very tall, others are shorter and much more manageable.

Also,
We use these differing features to our avantage as gardeners- so it's helpful to select varieties matching your needs.

Determinate types are great if salsa or sauce is your goal, as they grow and then ripen a concentrated set all at the same time- big harvest, then processing that big harvest. A prime example is a paste tomato (like roma) that is determinate- bred for this reason. Or, a tomato bred for patio (potted) growing.

Indeterminate- these give a more continual harvest throughout the season as they ripen fruit, vine out more, then set and ripen more.
This is great if you need a few continually throughout the seadon for eating on burgers or in salads and other fresh use- but is frustrating if you need a whole big bowl of ripe 'maters all at once for processing sauce or canning juice. You'll end up freezing them periodically as you harvest until you have what you need.

I'd like to know what you've been fertilizing with.

I tried chicken poop a couple times on the tomato plants, and because of the high amount of nitrogen, the plants grew tons of green leafy, and rather few maters...

If you've been adding too much chemical fertilizer, the same result may be happening at your house.
