Tomato 'Ultrasonic'

Try to plant in a location that enjoys full sun and remember to water moderately. Ultrasonic is generally regarded as a tender plant, so it is really important to plant out well after your last frost date. Ultrasonic needs a loamy soil with a ph of 5.5 to 7.5 (weakly acidic soil to weakly alkaline soil).

Start seeds indoors six weeks before last frost date.

Sow at a depth of approx. 0.39 inches (1.0 cm) and aim for a distance of at least 0.78 inches (2.0 cm) between Tomato plants. For optimal germination, soil temperature should be a minimum of 12°C / 54°F.

Plant to the first set of true leaves to promote strong root growth.

Ultrasonic is tender, so ensure you wait until all danger of frost has passed in your area before considering planting outside.
