Growing Quarter Century Slicer Tomatoes in the Vegetable Garden
Seven to nine weeks before the last spring frost, begin your tomato seeds indoors in seed starting trays. Use a well-draining potting or germinating mix to start the seeds, we recommend using Minute Soil Coco Coir. Plant two or three seeds per cell about a quarter inch deep and cover the seeds. Water them in gently to avoid washing the seeds away. Water regularly. As soon as one of the seedlings emerges, move the tray to a bright window or provide grow lights positioned a few inches above the tray. The seedlings should receive at least 8 hours of direct sunlight combined with 8-10 hours of darkness. When they are 1-2 inches tall, thin the seedlings to one per cell. Fertilize once they have two sets of true leaves. Transplant the seedlings into larger, 4 or 6-inch pots once their root systems have developed beyond the starting cell’s capacity, but a few weeks before they can be moved outdoors. Before planting them into your garden soil, the seedlings should be hardened off gradually to acclimate to the sunnier, windier conditions.
Transplant the seedlings into the garden once temperatures are consistently above 70 F. Protect the plants from cool weather; they are not cold-tolerant. Garden quilts, cloches, cold frames, or other protections can be used if cool weather is expected below 50-55 F. All tomato varieties need warmer conditions and rich soil in order to thrive and develop fruit. Quarter Century tomatoes prefer loamy, well-drained soil with neutral to slightly acidic pH and added compost.Burying a calcium supplement in the soil beneath the seedlings can help encourage healthy growth. Bury most of the stems to encourage more root development. Leave at least one good set of leaves at the top. Remove the lower leaves that can’t reach the sunlight or might be buried, and any suckers growing in between fruit-bearing branches. Burying tomatoes deep allows roots to develop from the stems. This is something that tomatoes are able to do, but not many other plants. Fertilize with compost, worm castings, or another fertilizer of choice when planting into the garden.
Prune the bush periodically throughout the season to remove suckers and bottom leaves. Tomatoes are highly sensitive to insufficient light and will not fruit if the light is too weak or short. Fertilize once more about mid-season. Be sure to water Quarter Century’s in the morning and focus the water at the base of the plant instead of an overhead spray. Water regularly to ensure proper nutrient uptake and avoidance of disease. Avoid soggy soil and splashing water onto the leaves.
Harvesting Quarter Century Slicer Tomatoes
Quarter Century produces for just a few weeks, but have a very heavy yield. Pick the tomatoes as soon as they ripen to avoid overloading the plant. They are best harvested off the vine when fully red and shiny but still firm. Gently twist the tomato off the calyx or snip it loose if it won’t come on its own. If the harvest buts up against a frost, pull up the plant and finish ripening the tomatoes off the vine indoors.
About Quarter Century Slicer Tomato Garden Seeds
This plant produces oblate-shaped, gorgeous red fruits, weighing in anywhere from 10-12 ounces each! This delicious tomato is equally suited for salads, sandwiches, canning, and more.

Tips From Our Gardeners
"Make sure your tomatoes get full sun! One year, I had a new garden plot and did not realize that one corner was far more shaded than I realized. I did everything else right, but the poor tomato plant only received about 4 hours of direct sun per day. Despite pruning, composting, and fertilizing, I did not get a single tomato that year!"
Solanum lycopersicum (Previously Lycopersicon esculentum, however this name is no longer accepted as correct)

Determinate - Determinate tomatoes are more compact, bush-type plants that set their fruit all at once and end the harvest. They won't continue to produce tomatoes after that. By planting multiple plants in intervals a week apart, you can continue to harvest for longer periods.
Well-draining, loose (sandy loam), slightly acidic (6.2 to 6.8), and moisture retaining. Too much nitrogen in the soil may lead to more foliage production and less fruiting. Tomatoes like more phosphorus and potassium than other vegetables.
Warmer (70-85 F)
Yes Start Indoors 7-9 weeks before your last spring frost date.
24 to 36 inches
Late - Ready to harvest from 81 days or more from transplant. Difficult, if not impossible, to get a tomato by the 4th of July with these varieties. They are good late-summer to early-fall producers for most USDA Zones.
Pests and Diseases:
Common pests known to harm tomato plants, in general, include the tomato hornworm, cutworm, aphids, flea beetles, tomato fruit worms, and whiteflies. Also, watch for common diseases such as blossom end rot, fusarium wilt, powdery mildew, verticillium wilt, late blight, bacterial canker/spot, and tobacco mosaic virus. Most of these can be prevented by maintaining a regular watering schedule and avoiding overwatering. Regularly check your plants for pest damage throughout the season. For treating pest and disease problems, we recommend using an organic neem-based product.
