Saving Seeds of Carrot
Carrot plants produce perfect flowers
(Fig. 10) that are pollinated by
insects. Separate different varieties
800 m apart. Remove wild carrot
weeds since they will pollinate with
Rogue off-types taking into
consideration the root color and
shape, plant habit, and plant vigor.
Plants that bolt and go to seed early
should be removed. Save seed from
many carrots to maintain crop vigor.
The seed turns brown 6 weeks after
pollination (Fig. 2). Before the seed
shatters, cut and place umbels into
paper bags to dry completely. Late-
season rains will reduce seed
quality. For small amounts,
handpick each umbel as it dries
brown. Large amounts of seed can
be harvested by cutting the entire
stalk as umbels begin to dry.
Carrot (Daucus carota) seed
production requires two years. Roots
form during the first year and then
require a cold period (at least 10
weeks of temperatures below 15 °C)
to stimulate flowering and seed
production. Two methods of
production are used:
Seed-to-seed. Pencil-sized or
larger roots are left in the ground
overwinter. In late fall, plants are
thinned to 5 cm apart, tops are cut
back to 5 cm high, and mulched.
Once temperatures rise in spring,
the mulch is removed and leaves will
regrow. After several weeks, a seed
stalk will appear. Superior plants are
thinned to stand up to 75 cm apart.
Root-to-seed. Harvest eating-
sized roots for replanting in early
spring. Clip tops to 5 cm and store
at 4 °C in a humid location or lay-
ered in sawdust or sand. Replant
roots 75 cm apart with soil just cov-
ering shoulders. Thi
