Look to ensure a distance
1.95 feet (60.0 cm) between seeds when sowing - bury at a depth of at least
0.2 inches (0.5 cm) deep. Soil temperature should be kept higher than
25°C / 77°F to ensure good germination.
By our calculations, you should look at sowing Raspberry Tart about 56 days before your last frost date.
Ensure that temperatures are mild and all chance of frost has passed before planting out, as Raspberry Tart is a half hardy plant.
