CERTIFIED ORGANIC. Selected for sweetness and productivity, Prairie Fire Organic is a compact, semi-determinate variety with small, elongated, pointy-tipped fruits. The sweet little fruits have bright red skins with subtle golden striping over a solid red interior. Most fruits average 8cm long. They are early maturing and abundant on vigorous, healthy plants that perform well in the greenhouse or the open field.
How To Grow, Timing: Start indoors in early spring over bottom heat. When seedlings germinate, remove from the heat and grow under bright lights. Grow seedlings on for 6-8 weeks at around 10°C. Early season tomatoes can be planted out once night time temperatures are reliably above 7°C – or later. Other types should be transplanted out when night time lows are 10°C or warmer – or later. Optimal soil temperature for germination: 25-35°C. With bottom heat seeds should germinate in 7-14 days.
How To Grow, Starting: Sow seeds 5mm-1cm deep. Keep seedlings under very bright light to prevent legginess. You may have to pot on seedlings more than once before they go out to allow for root growth. Space bush (determinate) transplants 45-60cm apart and vine (indeterminate) types 50-75cm apart in rows 1m apart.
How To Grow, Growing: Ideal pH: 6.0-6.8. Tomatoes like fertile, well drained soil that is rich in organic matter. Dig in finished compost and manure, and add 1 cup balanced organic fertilizer beneath each transplant. The nutrition from heavy clay soils is excellent for tomatoes, but they are slow to warm, so transplanting should be done later. By the same token, lighter soils warm more quickly, so transplants can go out sooner. Adding glacial rock dust will supply all the calcium they will need. Regular watering is vital, but don’t let the plants sit in water. Tomatoes are tropical plants so they require full sun and lots of heat. Vine varieties will require some kind of support such as a wire to grow up, or a trellis to be tied to as the plant grows. Bush types benefit from the support of a tomato cage in order to prevent sprawling. At the time of final transplant, plants can be buried up to their first pair of true leaves. This will encourage greater root growth, helping with both nutrient uptake and the plants’ ability to stand up to dry conditions.
Stop watering around the end of July to encourage the fruit to ripen. If tomato plants are grown under cover, you can encourage pollination and fruit set by tapping the stem from time to time. Tomatoes do not rely on insects for pollination. Vibrating the plant shakes pollen loose within the flowers, which then self-pollinate.
Indeterminate tomatoes continue to grow and produce fruit until they are killed by frost. Remove any suckers (stems growing from the crotch of leaves) to keep the foliage under control, and they will set a later crop of larger fruit. Determinate varieties normally set fruit in a concentrated time period. Their suckers are not normally removed, though some trimming helps with ventilation.
How To Grow, Harvest: Harvest when the fruit is the desired colour. Green tomatoes can be ripened indoors at a cool temperature when they are blemish free. Very dark green tomatoes are unlikely to ripen fully.
