Quick Growing Facts

When & Where to Grow ‘Large Red Cherry’ Tomatoes

Tomatoes need heat, sun, and a long growing season. ‘Large Red Cherry’ is a productive indeterminate variety that will reward you with clusters of sweet fruits from mid-season until frost when planted in a warm, sunny location and supported properly.

• Start indoors: Sow seeds indoors 6–8 weeks before your last expected frost date.
• Transplanting time: Move plants outside only after all danger of frost has passed and night temperatures are consistently above about 50°F (10°C).
• Location: Choose the sunniest, warmest spot you have—south-facing beds, walls, or fences are ideal.
• Containers: Grow in large pots or grow bags (at least 5–7 gallons / 19–26 L per plant) with a sturdy cage, stake, or trellis.

Soil Preparation

Tomatoes are heavy feeders with deep root systems. Deep, rich soil helps them anchor, access water, and fuel flowering and fruiting through the season.

• Loosen the top 10–12 in (25–30 cm) of soil and remove weeds, roots, and stones.
• Mix in plenty of compost or well-rotted manure to improve fertility, structure, and moisture retention.
• In poorer soils, add a balanced organic fertilizer at bed preparation following label directions.
• Ensure good drainage—tomatoes dislike standing water; raised beds help in heavy or compacted soils.

Starting ‘Large Red Cherry’ Indoors

Starting tomatoes indoors gives them a head start in cooler climates and ensures strong, healthy transplants ready to take off when the weather warms.

• Fill cell trays or small pots with a fine, well-draining seed-starting mix.
• Sow seeds about 1/4 in (6 mm) deep and lightly cover with mix or vermiculite.
• Keep the mix evenly moist and maintain 70–80°F (21–27°C) until germination; a heat mat helps speed sprouting.
• Once seedlings emerge, provide bright light (sunny window or grow lights 12–16 hours per day) to prevent stretching.
• When seedlings have 2–3 sets of true leaves, pot up into larger containers if needed to keep roots growing strongly.

Hardening Off & Transplanting

Gradual acclimation to outdoor conditions helps prevent transplant shock and keeps plants growing steadily once they are planted outside.

• Begin hardening off 7–10 days before transplanting by placing seedlings outdoors for a few hours a day, gradually increasing time, sun, and exposure to wind.
• Transplant after frost when soil is warm and nights are mild.
• Space plants 18–24 in (45–60 cm) apart in rows or beds, with 30–36 in (75–90 cm) between rows.
• Bury stems deeply when planting—remove lower leaves and plant so that only the top cluster or two of leaves is above the soil. Tomatoes form roots along buried stems, creating stronger plants.
• Water thoroughly after planting to settle soil around roots and install stakes, cages, or trellises at planting time.

Direct Sowing Outdoors (Warm Climates Only)

In very warm, long-season climates, tomatoes can be sown directly outdoors, though most gardeners still prefer transplants. If direct sowing:

1. Wait until soil is consistently above 65°F (18°C) and all danger of frost has passed.
2. Sow seeds 1/4 in (6 mm) deep, keep evenly moist, and thin seedlings to final spacing once they are several inches tall.
3. Provide protection from intense sun and pests while plants are very young.

Support & Pruning

As an indeterminate variety, ‘Large Red Cherry’ vines keep growing and producing all season. Good support and light pruning improve airflow, make harvesting easier, and keep fruit clean and accessible.

• Use sturdy stakes, cages, or trellises at least 4–6 ft (1.2–1.8 m) tall.
• Secure stems loosely to supports with soft ties as they grow.
• For a tidier plant, pinch out some of the side shoots (“suckers”) that grow from the leaf axils, especially in lower parts of the plant.
• Avoid removing too much foliage; leaves protect fruits from sunscald and fuel growth.

Watering & Feeding

Tomatoes need consistent moisture and steady nutrition for juicy, crack-free fruit and continuous production. Sudden swings from dry to wet can cause cracking and blossom-end issues.

• Watering: Provide about 1–1.5 in (2.5–4 cm) of water per week, more in hot or windy weather. Water deeply and less often rather than frequent light watering.
• Mulch: Apply compost, straw, or other organic mulch once soil has warmed to conserve moisture, reduce weeds, and moderate soil temperature.
• Feeding: Side-dress with compost or a tomato/vegetable fertilizer a few weeks after transplanting, and again when the first fruits set and mid-season.
• Avoid overfeeding with nitrogen: Too much nitrogen produces lush foliage and fewer fruits; aim for balanced fertilizers that support flowering and fruiting.

Flowers, Pollination & Fruit Set

Tomato flowers are largely self-pollinating, but gentle movement from wind and insects helps shake pollen loose and improves fruit set.

• Clusters of yellow flowers can each set a cherry tomato; gentle tapping of supports on still days can help move pollen.
• Very high heat (above ~90–95°F / 32–35°C) or cold nights (below ~55°F / 13°C) can cause blossoms to drop without setting fruit.
• Keep plants evenly watered and well-fed during flowering for reliable fruit set and good fruit size.

Pests & Diseases

Tomatoes can attract a range of pests and diseases, but good spacing, healthy soil, and regular monitoring keep most problems manageable. Cherry types like ‘Large Red Cherry’ often outproduce minor issues.

• Aphids & whiteflies: Suck plant sap, causing curled leaves and sticky honeydew. Spray with water or use insecticidal soap if needed.
• Tomato hornworms & other caterpillars: Large green caterpillars can defoliate plants quickly. Hand-pick and remove when seen.
• Spider mites: Tiny pests that cause stippling and webbing in hot, dry conditions. Increase humidity and use appropriate organic controls if necessary.
• Early blight, septoria leaf spot & other fungal diseases: Cause spots and yellowing on leaves. Provide good airflow, avoid overhead watering late in the day, and remove affected lower leaves.
• Blossom-end rot: Dark, sunken spots on the blossom end of fruits, usually from inconsistent watering and calcium uptake issues. Maintain even soil moisture and avoid root stress.
• Crop rotation: Rotate tomatoes and other nightshades (peppers, eggplant, potatoes) to new beds each year to reduce disease buildup.

Harvesting ‘Large Red Cherry’ Tomatoes

Cherry tomatoes are at their best when fully colored, slightly soft to the touch, and picked often. Regular harvesting keeps vines producing heavily.

• Begin checking plants daily once fruits start to turn from green to red.
• Harvest when fruits are fully red, glossy, and slightly yielding to gentle pressure.
• Pick with a gentle twist or snip with small scissors, taking care not to tear stems.
• Harvest frequently—every day or two during peak season—to encourage continuous flowering and fruit set.

Storing & Using Cherry Tomatoes

• For best flavor and texture, store ripe tomatoes at cool room temperature and use within several days.
• Avoid refrigerating unless fruits are very ripe and you need to slow spoilage; cold temperatures can dull flavor and affect texture.
• Use fresh in salads, on snacks and platters, in pasta dishes, skewers, salsas, and as colorful toppings.
• Surplus harvests can be roasted, dried, or turned into sauces and relishes.

Saving Seed from ‘Large Red Cherry’

If your ‘Large Red Cherry’ seed is open-pollinated and not a hybrid, you can save seed from healthy, true-to-type plants. Tomatoes are mostly self-pollinating, but some crossing can occur.

• Select vigorous plants with good flavor and productivity for seed saving.
• Allow fruits to fully ripen on the vine until very soft and deeply colored.
• Cut fruits open, squeeze out seeds and gel into a jar or bowl, and add a little water.
• Ferment for 1–3 days at room temperature, stirring daily, until a light mold film forms on top—this helps remove the gel coat.
• Rinse seeds thoroughly in a sieve, removing pulp and mold, then spread seeds in a thin layer to dry completely in a warm, shaded, well-ventilated place.
• Store dry seeds in a labeled, airtight container in a cool, dark, dry place; tomato seeds can remain viable for several years under good conditions.

Tips for Success

• Don’t rush planting—wait for warm soil and nights to avoid stunted plants.
• Use strong support early; it is much easier to train vines as they grow than to untangle them later.
• Water deeply and consistently to reduce cracking and blossom-end problems.
• Remove lower leaves that touch the soil to improve airflow and reduce disease risk.
• Rotate tomato beds yearly and keep foliage dry whenever possible to maintain healthy plants all season.

Note: Growing conditions and timing vary by region. Adjust sowing dates, watering, and frost/heat protection to match your local climate and weather patterns.
