This morning I have sown two seeds of tomato Tigerella from Thompson & Morgan.Cordon (Indeterminate).greenback free, crops heavily and over 3 weeks earlier than Moneymaker. It grows well outdoors or in a greenhouse in all areas, has a rich, tangy flavour uniquely its own – and clearly defined red and yellow stripes! For greenhouse culture sow late winter to early spring. Germination usually takes 6-14 days.
