Yellow Radiance is a large, open-pollinated beefsteak tomato developed by California seed breeder Brad Gates. Bright yellow fruit carries vibrant stripes, meaty flesh, and an old-fashioned sweet flavour with citrus notes. Fruit can reach approximately 1 pound and is produced abundantly on an indeterminate plant requiring a sturdy cage. Gaia lists maturity at 75 days in its description and 75 to 80 days in the technical table. The packet contains approximately 25 organic seeds certified by Ecocert Canada, lot GO23145, with reported germination above 85%. Broad, colourful slices suit salads, sandwiches, bruschetta, and summer platters served with herbs, mild cheese, or olive oil.

‘Yellow Radiance’ Tomato, organic seeds (Solanum lycopersicum) Developed by California seed breeder Brad Gates, Yellow Radiance produces large beefsteak fruit with a bright yellow background and vibrant stripes. Gaia describes an old-fashioned sweet flavour with citrus notes and meaty flesh suited to thick slices, salads, and sandwiches. Fruit can reach approximately 1 pound and is produced abundantly on an indeterminate plant that needs strong support. The packet contains approximately 25 open-pollinated seeds certified organic by Ecocert Canada, lot GO23145, with reported germination above 85%. Fully ripe fruit creates a bright contrast on summer platters and in mixed tomato salads.

Start seeds indoors 6 to 8 weeks before transplanting, approximately 1/8 to 1/4 inch deep. Gaia lists germination in 5 to 10 days across a 10 to 35°C range, with an optimum of 23 to 29°C. Maintain moisture without standing water and provide bright light immediately after emergence. Harden plants off gradually over 7 to 14 days, then transplant after all frost risk has passed into warm, fertile, well-drained soil. Space plants 24 to 36 inches apart and rows 4 to 6 feet apart. Install a large cage or stake at planting to support long stems and heavy fruit throughout the growing season.

Water deeply at soil level to maintain even moisture, especially during flowering and fruit enlargement. Compost-enriched soil with a pH of approximately 5.5 to 7 supports growth, but excessive nitrogen can delay fruiting. Gaia lists maturity at 75 days in the descriptive text and 75 to 80 days in the technical table. Harvest when the bright yellow background and stripes are fully developed. Fruit that has begun to lighten or turn yellow can finish ripening at room temperature. Ripe fruit is edible, but keep the leaves, stems, and green tomatoes away from pets. Store whole unripe fruit in one layer and check it regularly as colour develops.

Uses in the garden

Grow Yellow Radiance in full sun in a warm, well-drained plot with enough room for indeterminate growth. Prefer a location where tomatoes, potatoes, eggplants, peppers, and tomatillos have not grown for three or four years to reduce diseases shared by Solanaceae crops. Place plants north of shorter vegetables to limit shade after they reach 4 to 6 feet or more. Preserve 24 to 36 inches between plants and 4 to 6 feet between rows so light and air can circulate. Install a large cage or stake at transplanting and tie stems with soft material. Clean straw mulch reduces soil splash and helps maintain even moisture. Water deeply at soil level rather than wetting foliage. Remove only leaves touching the ground or showing clear symptoms; excessive pruning exposes fruit to sun. Check supports often as tomatoes approach 1 pound. In a small space, a container holding at least 40 L can work when drainage, daily moisture checks in hot weather, and stability are maintained. Label the support with Yellow Radiance and lot GO23145 so the correct variety remains matched with fruit and any saved seed. Place harvested fruit in a shallow tray rather than stacking it, since the weight of upper tomatoes can bruise fully ripe beefsteaks.

01 How many Yellow Radiance tomato seeds are in the packet?

The Gaia packet contains approximately 25 Yellow Radiance tomato seeds certified organic by Ecocert Canada. Lot GO23145 reports germination above 85%. Gaia identifies this garden crop as annual, open-pollinated, and indeterminate. Keep the packet or label with seedlings so the variety name, lot number, and germination details remain available. Because the quantity is approximate, a small variation may occur. Sow only as many plants as can be spaced 24 to 36 inches apart and supported with a large cage or sturdy stake. Fruit reaching 1 pound and continuous growth require more room and support than a compact tomato, particularly in windy or exposed garden locations. Open pollination allows seed saving from healthy, fully ripe fruit when crosses with nearby tomato varieties have been prevented.

02 How should Yellow Radiance tomato seeds be started?

Start seeds indoors 6 to 8 weeks before transplanting, approximately 1/8 to 1/4 inch deep in clean, moist seed-starting mix. Gaia lists a 10 to 35°C range and an optimum of 23 to 29°C. Keep the mix moist without standing water and provide bright light as soon as seedlings emerge. Once plants are sturdy, expose them gradually to outdoor wind and sunlight over 7 to 14 days. Transplant only after frost risk has passed and the soil has warmed. Space plants 24 to 36 inches apart, allow 4 to 6 feet between rows, and install support immediately so roots are not disturbed by later staking.

03 How long does Yellow Radiance germination take?

Gaia lists germination in 5 to 10 days across a 10 to 35°C range, with an optimum of 23 to 29°C. Lot GO23145 reports a rate above 85%, but this result does not guarantee every seed under all conditions. Use clean seed-starting mix, maintain consistent moisture without saturation, and provide stable warmth. Move seedlings into bright light immediately after emergence to prevent long, weak stems. If some seeds take longer, keep the tray under suitable conditions for the full listed period before deciding they have failed. Label the container Yellow Radiance clearly so this variety remains separate from other tomatoes during indoor growing, transplanting, and gradual hardening off.

04 How much space and support does Yellow Radiance need?

Allow 24 to 36 inches between plants and 4 to 6 feet between rows. Yellow Radiance is indeterminate, so its stems continue extending and producing until cold weather. Install a large cage or sturdy stake at transplanting to avoid damaging roots later. Gaia lists a typical height of 4 to 6 feet and width of 2 to 3 feet, although the plant may grow taller during a long season. Place it in full sun, preferably north of shorter crops. Tie stems with soft material and check support often as fruit approaches 1 pound. Keep foliage off the ground and preserve airflow around neighbouring plants to reduce disease pressure throughout summer.

05 When should Yellow Radiance tomatoes be harvested?

Harvest after fruit reaches useful size and its bright yellow background and stripes are fully developed. Gaia lists 75 days in its descriptive text and 75 to 80 days in the technical table, so weather and the actual transplanting date can shift harvest timing. Mature fruit whose green colour has begun to lighten or turn yellow can finish ripening at room temperature. Arrange tomatoes in one layer without touching and check them often. Also pick fruit that has begun changing colour before the first frost. Use ripe tomatoes promptly, refrigerate cut portions in a covered container, and discard any fruit showing advanced decay rather than trying to ripen or preserve it.
