Radish 'Scarlet Globe' Raphanus sativus 'Scarlet Globe'

Water

Radishes require consistent moisture, so water the 'Scarlet Globe' radish gently to avoid washing away the seeds or seedlings. Water them with 1-2 inches of water weekly, although this may vary depending on soil conditions and climate. It's best to water the plants in the morning to allow leaves to dry out during the day and reduce the risk of leaf diseases. Ensure that the soil is moist but not waterlogged, as radishes can rot in overly saturated soil. During periods of dry weather, you may need to water radishes more frequently to maintain the necessary moisture levels.

Light

The 'Scarlet Globe' radish thrives in full sunlight, which means it needs at least six hours of direct sunlight each day. Place the radishes in a spot where they receive ample sunlight without being shaded by taller plants. Full sunlight will ensure healthy growth and optimal development of the radish bulbs.

Temperature

The 'Scarlet Globe' radish grows best in cooler temperatures, with an ideal range of 50°F to 65°F. These radishes can survive temperatures as low as 40°F and as high as 85°F but perform best within the cool to mild range. To ensure robust growth and a good crop, avoid extreme heat or cold.

Pruning

Pruning is not typically required for 'Scarlet Globe' radishes as they are harvested before they reach a size that would necessitate trimming. The focus should be on thinning seedlings early in the growing process to allow for proper bulb development. Thin radishes to approximately an inch apart when seedlings are a few inches tall to ensure adequate space for growth.

Cleaning

Not needed

Soil

Scarlet Globe radishes require a soil mix that drains well and is rich in organic matter. A mix of garden soil, compost, and perlite or sand works well for these radishes. They prefer a slightly acidic to neutral pH between 6.0 to 7.0 for optimal growth.

Repotting

The Scarlet Globe radish, commonly referred to as radish, does not require repotting as it is an annual vegetable grown from seed and harvested before it would need repotting.

Humidity & Misting

Radishes like the Scarlet Globe variety prefer average ambient humidity and do not require specific humidity conditions to thrive, as long as soil moisture levels are maintained through regular watering.

Suitable locations

• Indoor

  Grow radishes in deep pots with ample light.

• Outdoor

  Plant in well-drained soil with full sun exposure.

• Hardiness zone

  2-11 USDA

Life cycle

The life of the 'Scarlet Globe' radish begins with seed germination, which occurs once the seed is exposed to moisture and the right temperature, typically in spring. This is followed by the seeding stage, where the radish starts to grow its first leaves, known as cotyledons, that push through the soil surface. Once true leaves develop, the plant enters the vegetative growth stage, focusing on developing its foliage and root system, with the unique radish bulb taking shape underground. As the plant matures, it reaches the flowering stage, where it produces small flowers that eventually lead to pollination and seed formation if not harvested earlier. If left unharvested, the plant will complete its life cycle by producing seeds that can be dispensed into the soil, ready to grow a new generation of radish plants once conditions become favorable. The radish is considered a fast-growing plant, often harvested for its edible root within three to four weeks after germination, or left to produce seeds and naturally complete its life cycle over several months.

Propogation

• Propogation time

  Spring

• The Raphanus sativus 'Scarlet Globe', commonly known as radish, is typically propagated through seed. The optimal time for sowing radish seeds directly in the garden is in the early spring as soon as the soil can be worked. The seeds should be planted about 1/2 inch deep with a spacing of 1 inch apart in rows that are 12 inches apart. The seeds usually germinate within a few days to a week, depending on soil temperature and moisture conditions. As they grow, thin the seedlings to about 2 inches apart to give each radish enough space to develop. This straightforward process makes seed propagation by far the most popular and effective method for growing radishes.
