Sow into soil at 16–29 °C

Tomato seed germinates well when the soil stays in its optimum range of 16–29 °C. At 20–30 °C seedlings typically appear in 6–8 days. Indoors, cover the seed with 3–6 mm of seed-starting mix. These figures are typical for the species, not a test of this packet.

Growing on

Sow indoors and plant out 60–90 cm apart into fertile, well-drained soil at pH 6.0–6.8. Stake or cage the vine to carry the fruit. It prefers warm, sunny conditions with steady moisture and no waterlogging.

When to expect fruit

Fruit ripens about 70–75 days after transplanting.
