Organic bicoloured dwarf ‘Wherokowhai’ tomato (Solanum lycopersicum ‘Wherokowhai’) is an open-pollinated organic variety created by the Dwarf Tomato Project and first offered publicly in 2014. Its stout dwarf plant has dense rugose potato-leaf foliage. It prolifically bears medium to medium-large oblate fruit weighing 115 to 400 g that ripens rich yellow with red swirls outside and through the flesh. Juicy meaty texture accompanies outstanding sweet complex well-balanced flavour.

Sow indoors six to eight weeks before last frost approximately 0.5 cm deep in warm evenly moist mix. Provide strong light immediately after emergence, pot up after true leaves, and harden gradually. Transplant after frost in full sun into fertile organic-rich well-drained soil. Despite its dwarf habit Wherokowhai continues producing through the season and its heavy fruit requires a compact sturdy cage. It suits gardens small spaces and large containers.

Water slowly and deeply at soil level when the surface begins to dry, then mulch after soil warms to stabilize moisture. Feed moderately without excess nitrogen and support loaded branches. The Dwarf Tomato Project generally lists maturity around 75 days after transplanting although other catalogues place it later. Pick when the yellow background is rich, red swirls are distinct, and fruit yields slightly to gentle pressure. Discard mouldy slimy deeply split or abnormal-smelling fruit.

Spacing / density

Space plants approximately 90 to 120 cm (36 to 48 in) apart to accommodate growth and air circulation.

Germination temperature

21 to 27°C (70 to 81°F)

Germination time

7 to 14 days

Sowing period

March through April indoors then transplant after frost

Propagation

Growing method

Sow Wherokowhai indoors March through April six to eight weeks before last frost 0.5 cm deep. Maintain 21–27°C and even moisture until emergence in 7–14 days. Provide intense light, pot up after true leaves, and harden gradually. After frost transplant in full sun in the ground or a large deep container. Install a cage or stake, water at soil level, and mulch. Harvest frequently approximately 75 days after transplanting once small fruit is uniformly red.

Soil and care

The right care,at the right time.

Soil pH

Approximately 6.0 to 6.8

Care level

Moderate

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 stout dwarf 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.

Moisture

Consistent soil moisture without saturation; good air circulation around the foliage.

Seasonal care

In spring sow indoors six to eight weeks before last frost and provide intense light immediately after emergence. Pot up after true leaves then harden gradually. After frost transplant in full sun in the ground or a large deep container. Install a cage or stake to support loaded stems without assigning an unconfirmed growth type. In summer water deeply at soil level, check container moisture often, mulch, and feed moderately. Harvest red fruit frequently. Before frost pick developed fruit, remove plants, and clean containers.

Container growing

A garden,within reach.

Choose a large stable deep container with numerous drainage holes; no exact size is confirmed for the Biologiquement Vôtre lot. Fill it with airy compost-enriched vegetable potting mix and place it in full sun. Install a compact sturdy cage at transplanting because large fruit can bend branches even though the plant stays dwarf. Water slowly when the surface begins to dry without standing water. Mulch lightly, feed moderately, and check moisture daily during hot or windy weather.

Bloom and dimensions

Its place,in your garden.

Foliage color

Green

Foliage type

Compound, divided foliage with an aroma when bruised; grown as an annual in Quebec

Growth rate

Vigorous during the warm season

Growth habit

Dwarf stout with a thick central stem and rugose potato-leaf foliage

Bloom period

Small yellow flowers borne in successive clusters during the warm season

Fruiting

Prolific crop of medium to large bicoloured fruit on a dwarf plant

Days to maturity

Approximately 75 days after transplanting according to the Dwarf Tomato Project

Harvest

Harvest generally around 75 days after transplanting when fruit has a rich yellow background, red swirls are clearly developed, and flesh yields slightly to gentle pressure. Because fruit can be heavy support it with one hand and clip the stem with a clean tool without tearing the branch. Place fruit in a single layer to prevent bruising. Before frost bring developed fruit indoors. Do not eat leaves or stems and discard mouldy slimy deeply split or abnormal-smelling fruit.

Garden associations

In goodcompany.

Companion plants

Basil and early lettuce can occupy nearby space when light, water, air circulation, and root room remain sufficient.

Plants to avoid

Avoid waterlogged soil, overhead watering, crowding, and repeated rotations with tomatoes, peppers, eggplants, or potatoes.

Frequently asked questions

Your questions,answered.

When should Wherokowhai be sown and transplanted in Quebec?
Sow indoors March 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 7–14 days. Provide intense light, pot seedlings up, and harden gradually. Transplant only after last frost once soil is warm and nights are sufficiently mild.
When should Wherokowhai tomatoes be harvested?
Generally harvest around 75 to 85 days after transplanting once fruit has developed red 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.
Can Wherokowhai be grown in a container?
Yes. The workbook indicates culture in a large deep container without confirming exact dimensions. Use a stable pot with several drainage holes and airy compost-enriched mix. Place in full sun, install a cage or stake for loaded stems, check moisture daily during hot weather, water until it drains without standing water, and feed moderately according to label directions.

Supporting wildlife

Small yellow flowers may be visited by bumblebees and other bees able to vibrate the anthers and release pollen. Wind also contributes substantially to pollination, although active insect visitors can support consistent fruit set in the vegetable garden during bloom.
