How to grow Radish 'German Giant'

Full Sun
+
Medium

Once seeds are germinated, water evenly — do not allow the radishes to either dry out or get too wet.

Try to plant in a location that enjoys full sun and remember to water moderately. Keep in mind when planting that German Giant is thought of as tender, so it is really important to plant out well after your last frost date. The USDA Hardiness Zones typically associated with German Giant are Zone 5 and Zone 14. Try to keep the ph of your soil between the range of 5.5 and 6.8 as German Giant likes to be in weakly acidic soil.

Growing German Giant from seed

Sow at a depth of approx. 0.47 inches (1.2 cm) and aim for a distance of at least 0.98 inches (2.5 cm) between Radish plants. Soil temperature should be kept higher than 13°C / 55°F to ensure good germination.

By our calculations, you should look at sowing German Giant about 28 days before your last frost date.

Transplanting German Giant

Do not transplant. Sow in stone-free soil in early spring to early summer, and again in late summer for fall crop (if desired). Thrives in cool weather. Make successive sowings every 2 weeks. The recommendation for most root radishes is to directly sow them 4 weeks prior to your last frost date. However, you can start sowing as soon as the ground has thawed and air temperatures are averaging over 40 degrees on most days. Depending on what your springs are like (short and fast, long and drawn out), these conditions may emerge much sooner than or much later than the 4 week guide might suggest. Don’t be afraid to experiment with your start date. Cloches can be used for extra-early plantings.

Ensure that temperatures are mild and all chance of frost has passed before planting out, as German Giant is a tender plant.
