Tomato 'Aunt Ruby's German Green' (Organic)
A large green tomato prized for its flavor, colour and versatility, this heirloom has a complex history, so while listed as an heirloom from Germany, it was actually cultivated in the USA by Aunt Ruby Arnold from Tennessee and has become a much-loved American favourite ever since.
Tomatoes are a warm season crop requiring temperatures of 15-29 degrees Celsius to grow and germinate successfully. Seed germinates best at 20-25 degrees Celsius, while the seedlings thrive from 15 degrees Celsius. Sow seed 6-8 weeks before you want to plant out your tomatoes. Sow in punnets or trays and maintain consistent moisture and temperature. Prick out and place in individual pots once true leaves appear and harden off at least one to two weeks before planting out. Plant tomato seedlings out when soil temperature reaches 15°C or more, and after risk of frost has passed. Plant in full sun and enrich the soil with compost and well-rotted manure. In pots, use a premium organic potting mix. Mulch and water regularly, especially during hot weather. Stake at planting and train to the stake as plants grow. Avoid overhead watering.
