Ace 55 Tomato Heirloom Seeds

Grow a classic red slicer for summer sandwiches and garden-fresh salads. Ace 55 produces firm, meaty tomatoes with a mild, sweet flavor on bushy plants commonly classified as determinate. Slice a ripe fruit thickly, add a little seasoning, and let its juicy texture take center stage.

Why Grow Ace 55?

• Classic slicing tomato: Red, round to slightly flattened fruits suit sandwiches, salads, and fresh kitchen use.
• Mild, sweet flavor: Enjoy a mellow tomato taste without relying on unverified low-acidity claims.
• Meaty texture: Firm flesh makes satisfying slices and works well in fresh salsa.
• Leafy, bushy growth: Good foliage helps shade developing fruit; support keeps branches off the ground.
• Heirloom and open-pollinated: Non-GMO seeds for a traditional vegetable garden.

Planting and Growing

Start indoors 6–8 weeks before your intended transplant date. Sow approximately ¼ inch deep in seed-starting mix, provide warmth for germination, and give seedlings strong light. Harden off gradually and transplant outdoors after frost danger has passed and conditions have warmed.

Choose full sun and fertile, well-drained soil. Add a sturdy cage or stake at planting time. Water consistently at soil level and mulch to help retain moisture. Avoid heavy pruning that removes the foliage shading developing tomatoes.

In a square foot garden, allow 1 plant per 4 sq ft (cage recommended). Leave enough room around the plant for airflow and harvesting. Roomy containers with drainage can also work with reliable watering and support.

Harvest Details

• Days to maturity: Approximately 75 days from transplant, as listed for your seed; some sources report later maturity.

• Growth habit: Commonly classified as determinate; cage or stake recommended.

Harvest when fruit is fully red and yields slightly to gentle pressure. Handle carefully to avoid bruising and enjoy fresh in sandwiches, salads, and salsa.

Frequently Asked Questions

Is Ace 55 a low-acid tomato?

It is often described that way, but mild flavor does not establish a tomato's acidity. This listing describes its flavor rather than promising a particular acid level.

Can I preserve the harvest?

For home canning, follow a current research-tested tomato recipe and all required acidification and processing directions. Do not choose a method based on a variety's flavor or a low-acid label.

Does it need support?

Yes. A cage or stake helps hold fruit-bearing branches above the soil and makes harvesting easier.
