Is La Roma Tomato Determinate or Indeterminate? A Guide to Growing This Popular Tomato Variety

La Roma tomatoes, also known as Roma or paste tomatoes, are a popular variety prized for their meaty flesh and few seeds – perfect for canning, sauces and paste. But an important question every gardener should ask before planting Roma tomatoes is – are they determinate or indeterminate?

The growth habit of Roma tomatoes can significantly impact how you grow them, from trellising and pruning to spacing and yield. So let’s take a deep dive into determinate vs indeterminate Roma tomatoes and how to provide the best care for a bountiful harvest

Determinate vs. Indeterminate Tomatoes – A Quick Refresher

Before diving into Roma tomatoes specifically let’s do a quick tomato growth habit recap

• Determinate tomatoes – Also called “bush tomatoes”, these plants stay compact and reach a determinate height, usually around 3-4 feet. They ripen all their fruit around the same time, typically over a 2-3 week period. Determinate tomatoes require little pruning and are ideal for containers.

• Indeterminate tomatoes – Also called “vining tomatoes”, these plants continue growing taller and producing fruit all season until killed by frost. They require staking or caging for support as they can reach 5-12 feet tall. Indeterminate tomatoes produce fruit steadily over the course of a season and benefit from pruning.

So which growth habit do Roma tomatoes typically exhibit? Let’s find out…

Are Roma Tomatoes Determinate or Indeterminate?

The short answer is – Roma tomatoes can be either determinate OR indeterminate depending on the specific variety.

While some Roma varieties are strictly determinate or indeterminate, others can display a more mixed habit with some determinate characteristics but also some indeterminate tendencies.

Let’s look at some examples:

• Determinate Roma varieties – Submarine, Plum Regal, La Roma III, Heinz 1439
• Indeterminate Roma varieties – Amish Paste, Mr. F’s, Opalka, Speckled Roman, Gypsy
• Semi-determinate Romas – Roma VF, Super Marzano

As you can see, there are Roma options for both growth habits, so it’s important to check your variety before planting to know what to expect.

If you’re unsure, observe the plant’s growth pattern – determinate Romas will grow bushy and compact while indeterminate varieties produce lengthy vines. Fruit production can also indicate the habit – determinate tomatoes yield heavily all at once while indeterminates bear steadily.

Growing Tips for Determinate Roma Tomatoes

If you’ve selected a determinate Roma variety, here are some tips for success:

• Give them ample space – Determinate Romas may stay compact but they produce a lot of fruit in a short window. Space plants at least 2 feet apart.

• Try containers – The compact size and high yields of determinate Roma tomatoes make them excellent container plants. Use at least a 5 gallon pot.

• Minimal support needed – Staking usually isn’t necessary for determinate Romas but small tomato cages can help keep plants tidy and elevated off the ground.

• Harvest all at once – Expect a flush of fruit 2-3 weeks after the first blooms appear. Pick all tomatoes as they ripen to avoid losses from pests or rot.

• Well-suited for canning & sauce making – The concentrated fruit set of determinate Romas is perfect for large batch preservation like canning tomato sauce or paste.

Growing Tips for Indeterminate Roma Tomatoes

If you’ve chosen an indeterminate Roma variety, use these tips:

• Give them space to sprawl – Indeterminate Romas can easily reach 5+ feet tall and wide. Space plants 3-4 feet apart or prune aggressively.

• Use sturdy stakes or cages – Indeterminate Roma vines need strong support. Use 5-7 foot stakes or robust tomato cages.

• Prune for productivity – Prune indeterminate Romas to 2-3 main stems and remove suckers for best fruit production and plant health.

• Harvest steadily – Pick ripe Roma tomatoes as they become ready every 1-2 weeks all season long. Don’t allow fruit to linger and rot on the vines.

• Great for fresh eating & cooking – The steady yields of indeterminate Romas allow you to enjoy fresh tomatoes and cook with them all summer.

Key Care Tips for Roma Tomatoes

Beyond growth habit considerations, here are some general care guidelines for growing healthy, productive Roma tomato plants:

• Full sun – Romas need at least 6-8 hours of direct sun per day. Insufficient light leads to low yields and weak plants.

• Rich soil – Prepare planting beds with compost or rotted manure to create fertile, well-draining soil. Romas are heavy feeders.

• Regular watering – Give Roma tomatoes 1-2 inches of water per week. Irregular water causes problems like blossom end rot.

• Mulch – Spread 2-3 inches of mulch around plants to retain moisture, suppress weeds and prevent soil splashing onto plants.

• Fertilize – Use a balanced fertilizer or one higher in phosphorus to nurture Roma plants. Side dress every 3-4 weeks.

• Rotate crops – Don’t plant Romas (or any tomatoes) in the same spot as last year to avoid disease buildup in the soil.

• Remove suckers & lower leaves – This improves air circulation and directs energy towards fruit production rather than vegetation.

Determinate or Indeterminate – Which is Best for Roma Tomatoes?

When it comes to choosing between determinate and indeterminate Roma tomatoes, neither growth habit is necessarily “better” overall. Gardeners should select the variety that best suits their specific goals and growing conditions.

Here are some factors to help decide which habit may be preferable for your needs:

• Available space – Indeterminate Romas need more room to sprawl. Choose determinate for smaller gardens.

• Support requirements – Determinate Romas need minimal staking while indeterminate varieties require strong trellises or cages.

• Harvest window – Determinates yield all at once while indeterminates produce steadily over months.

• Purpose – Determinate Romas work well for large batch canning. Indeterminate gives a continuous supply for fresh eating & cooking.

• Time investment – Indeterminate Romas require more pruning and attention throughout the season compared to determinate varieties.

No matter which growth habit you end up choosing, following the growing tips above and providing adequate care will set your Roma tomatoes up for success. Just be sure to select a variety suited to your space limitations, support capabilities, and harvesting preferences.
