Sow indoors February through April approximately six to eight weeks before planned transplanting. Place seed 0.5 cm deep, maintain 21–27°C, and keep mix moist; emergence generally takes 5–10 days. Provide intense light, pot seedlings up, and harden gradually. Transplant only after last frost once soil is warm and nights are sufficiently mild.

Organic white ‘Great White’ tomato (Solanum lycopersicum ‘Great White’) is an organic open-pollinated indeterminate variety with large cream to pale-yellow fruit. Dense juicy low-acid flesh offers sweet delicate refined flavour for salads fresh slices and tasting platters. The workbook lists approximately 30 seeds, height of 1.8–2.1 m, spread of 60–90 cm, and maturity around 80 days after sowing. The structured field classifies it as non-heirloom.
Sow indoors February through April approximately 0.5 cm deep. Maintain 21–27°C and even moisture; germination generally takes 5–10 days. Provide intense light immediately after emergence, pot up once true leaves develop, then harden gradually. After last frost transplant in full sun into deep fertile organic-rich well-drained soil. Space generously and install a sturdy cage or stake immediately to support growth and large fruit.
Water deeply and consistently at soil level without saturating the ground, then mulch once it is warm. Tie stems and support heavy fruit throughout summer. Harvest when fruit is uniformly cream coloured and yields slightly to gentle pressure; ripe colour remains pale and should not be judged like a red tomato. Monitor cracking blossom-end rot insects and foliar disease. Pick before frost and discard mouldy slimy or abnormal-smelling fruit.
Planting guide

Growing method
Sow Great White indoors February through April 0.5 cm deep. Maintain 21–27°C and even moisture until emergence in 5–10 days. Provide intense light, pot up after true leaves, and harden gradually. Transplant after frost into deep fertile organic-rich drained soil in full sun. Space 60–90 cm apart, immediately install a sturdy cage, water at soil level, and mulch. Harvest near 80 days after sowing once fruit is uniformly cream coloured and slightly yielding.
Soil and care

Full sun
Soil pH
Approximately 6.0 to 6.8
Minimum temperature
10°C (50°F)
Watering
Water deeply at soil level when the top three to five centimetres begin to dry while maintaining moisture as evenly as possible. Alternating drought and heavy watering encourages cracking and may contribute to blossom-end rot while constantly waterlogged soil suffocates roots and increases disease. Water in the morning without unnecessarily wetting foliage then mulch once soil warms. During fruit set and sizing avoid prolonged water stress. In a large container check moisture daily during hot weather without leaving standing water in the saucer.
Soil type
Choose deep fertile loose well-drained organic-rich soil with a slightly acidic to neutral pH near 6.0–6.8. Incorporate mature compost before transplanting while avoiding fresh manure and excess nitrogen that produces leaves at the expense of fruit. Work soil when neither sticky nor dusty and do not compact the root zone. Even moisture and adequate calcium reserves support healthy fruiting without automatic calcium additions unless testing supports them. Rotate three or four years away from tomatoes peppers eggplants and potatoes.
Fertilization
Incorporate mature compost before transplanting then base later feeding on a soil test or the label of a balanced fruiting-vegetable fertilizer. Avoid excess nitrogen which promotes very vigorous stems and leaves but delays flowering and ripening. After fruit set balanced nutrition including potassium and phosphorus may support fruiting without exceeding label rates. Never place concentrated fertilizer against roots and water after application. In containers split a dilute solution rather than using one strong dose. No calcium supplement replaces even watering or a test confirming deficiency.
Seasonal care
In spring sow indoors six to eight weeks before last frost and provide intense light immediately after emergence. Pot up once true leaves develop then gradually harden. In summer tie stems and support heavy clusters with a strong cage or trellis. Water deeply at soil level, maintain clean mulch, and remove only diseased leaves or those touching soil. Monitor cracking blossom-end rot aphids and foliar diseases. Harvest red fruit as it ripens. In fall pick before frost, remove plants, and plan a three-to-four-year rotation.
Container growing
A controlled environment.
Recommended pot size
45 to 60 cm (18 to 24 in)
Choose a very stable 50–75 L container at least 45–60 à 90 cm deep and wide with several drainage holes. Fill with airy vegetable potting mix enriched with compost. At planting install a very strong cage or stake capable of supporting a 1.8–2.1 m indeterminate plant and heavy large fruit. Place in full sun, water slowly when the surface begins to dry, and never leave the pot in a water-filled saucer. Mulch lightly, feed moderately for fruiting vegetables, tie stems, and check moisture daily during hot weather.

Harvest
The workbook lists approximately 80 days after sowing. Harvest when large fruit is uniformly cream coloured and yields slightly to gentle pressure. Ripe colour remains cream to pale yellow; do not wait for it to turn red. Support each fruit with one hand and cut the stem with a clean tool to avoid tearing the cluster. Pick progressively because the indeterminate plant continues producing. Before frost bring developed fruit indoors. Do not eat leaves or stems and discard mouldy slimy or abnormal-smelling fruit.

Frequently asked questions
Everything toknow.
The workbook confirms indeterminate growth. The plant therefore continues growing and fruiting until cold nights rather than concentrating harvest in a short period. At transplanting install a tall cage trellis or very strong stake and tie stems with soft ties. Listed height is 1.8–2.1 m and large fruit requires particularly sturdy support.
Generally harvest around 80 days after sowing once fruit has developed cream to pale yellow colour and yields slightly to gentle pressure. A green area may remain at the shoulders and colour varies with sunlight. Support each fruit and cut the stem with a clean tool. Pick progressively, bring developed fruit indoors before frost, and discard mouldy slimy or deeply split fruit.
Yes but use a very stable 50–75 L container 45–60 à 90 cm deep and wide with excellent drainage. Install very strong support at planting for a 1.8–2.1 m plant and heavy fruit. Place in full sun, check moisture daily during hot weather, water deeply without standing water, and feed lightly according to a fruiting-vegetable fertilizer label.
Yes. The workbook identifies this variety as heirloom and open-pollinated. To reduce crossing isolate blossoms intended for seed or adequately separate cultivars. Choose a healthy typical fruit, let it fully ripen, collect seed and gel, then follow a recognized fermentation rinsing and complete drying method. Label with cultivar and year. Do not use diseased or atypical fruit as a seed source.
