Types of Radishes
|
|
Radishes (Raphanus sativus) are hardy annuals in
the Brassicaiceae family, which
includes broccoli, Brussels sprouts, cabbage, cauliflower, collards, kale,
kohlrabi, turnips, mustards, watercress and horseradish. Most varieties are
best harvested young, but some are specifically selected as winter storage
radishes.
|
|
Soil and
Nutrient Requirements
|
|
Remove
stones from loose, well drained soil with pH 5.8-6.8. Go easy on nitrogen, as
excessive amounts can lead to big tops and little roots.
|
|
Position
|
|
Full sun
to part shade
|
|
Seeding Depth
|
|
Planting
depth: 1/4-1/2”
|
|
Plant Spacing
|
|
Plant
spacing: for garden radishes 1”, for daikon 4-6”. Thin if necessary to ensure
even sizing.
|
|
Row Spacing
|
|
For
garden radishes 8-12”, for daikon 12-16”.
|
|
When to Sow
|
|
Radishes
can be direct seeded as soon as soil can be worked and are best adapted to
the cooler temperatures and shorter day-length of spring and fall. Optimal
soil temperature for germination is 65-85°F. Seedlings emerge within a few
days. Plant every 10 days for a continual supply. Winter radishes should be
planted to mature around fall frost date.

Seed Coating /
Pelleting Info
|
|
Some of
the varieties we carry receive an organic film coating applied to the seed,
which make the seed easier to see during planting.
|
|
Harvest
|
|
Harvest
radishes on time as they do not hold well in the field, especially in warm
weather when roots tend to become pithy and pungent.
|
|
Storage
|
|
Topped
radishes will keep good quality for 3-4 weeks if store at near freezing
temperatures with high humidity in semi-permeable containers.
|
|
Pest Info
|
- Flea beetles can present a
problem, particularly for young plants, by chewing small holes in the
leaves. Healthy plants usually outgrow the damage to produce a
fine crop. Where undamaged leaves are desired or flea beetles are especially
problematic, use floating row cover (see Supplies) from time of planting
until two weeks after leaves emerge.
- Floating row cover also helps
prevent the cabbage root maggot, which feeds on the plant roots.
|
|
Disease Info
|
- Like other crucifers, radishes
can be subject to fungal diseases in wet seasons, such as Alternaria
Leaf Spot and White Mold (sclerotinia).
- Clubroot is a soil borne
disease which stunts the roots of the plants so that they are not able
to develop normally. Rotate crops and add lime to raise soil pH to 7.2.

Seed Saving
Instructions
|
|
Insect pollinated. Different radish varieties should be
isolated by a distance of ¼ mile to prevent cross pollination. The distance
may be shortened if physical barriers exist such as tree lines, buildings or
woods. Thin plants to 6" apart and allow to bolt and flower. Some
staking will be necessary as the plants will grow to 3'-4'. Allow the seed
pods to become papery and dry and harvest the entire plants. Some further
drying may be necessary before threshing. A ¼" screen on top of a
1/8" screen can be used for cleaning the seed. Radish seeds remain
viable for 5 years under cool and dry storage conditions.
