Chard
|
|
Chard (Beta vulgaris) is a hardy biennial in
the Chenopodiacea family, which
includes spinach, beets, orach and quinoa. Chard is actually a type of beet that has
been specialized for leaf production.

Soil and Nutrient
Requirements
|
|
Chard
appreciates loose well drained soils with acidity between 6.2 and 6.8, but
will tolerate 6.0-7.5 and a wide range of soil textures. Heavy clay soils can
be helped by the addition of organic matter.
Optimal soil temperature for germination is 55-75°F.Fertilize with the
ratio of 1-2-2 (N-P-K) seven days before seeding. 1-3 side dressings may be
necessary.

Plant Spacing
|
|
Direct
seeding: For babyleaf sow ~40 seeds/ft in 2-4” bands; for full size leaves
thin plants to 4-8" depending on desired leaf size.
|
|
Row Spacing
|
|
Row
spacing: for full size 18-24", for baby leaf 2-4” between bands.

When to Sow
|
|
Chard can
be direct seeded mid-spring through mid-summer and into fall in warmer
regions. Transplants can be started indoors or in a cold frame 4-6 weeks
before planting and transplanted outdoors after danger of frost has passed.
Transplants result in earlier harvests. Optimal germination temperature is
55-75°F. Days to maturity from direct seeding; if transplanting, subtract
14-21 days. Babyleaf varieties grow well in summer months when it is too hot
for lettuce. Sow every week for a continual summer harvest until 4 weeks
before frost date. Ready to harvest after five weeks, when leaves are ~3”,
growth rate is weather dependent.

Harvest
|
|
Harvest
full size leaves at any stage. Continuous harvests will encourage new growth.
Use floating row covers to extend the season.
|
|
Storage
|
|
Cool with
water immediately after harvest; stores best in plastic bags in the
refrigerator.

|
Pest Info
|
- Spinach Leaf Miners, Aphids,
Leaf Hoppers and Flea Beetles can cause foliar damage, rotate fields if
present to avoid over wintering populations. Row cover can reduce some
types of insect damage.
- Cabbage Maggot can infect
transplants and young seedlings as they feed on roots; use nematodes to
alleviate transplant damage in trays.

|
Disease Info
|
- Leaf spots are commonly
caused by either Cercospora beticola or Phoma batae and are most
prevalent in mid-late summer, during periods of frequent rainfall and
high humidity.
- Pocket Rot is caused by the
fungus Rhizoctonia solani and is spread plant to plant creating pockets
of infected plants.
- Damping off is caused by a
number of individual fungi. Downy Mildew, Pernospora sparsa, may appear
in mid-to- late summer.
- There are no resistant chard
varieties available for these diseases. Prevention includes removal of
plant debris, crop rotation (preferably with grains), and increased air
circulation

Seed Saving
Instructions
|
Wind
pollinated biennial. Different chard varieties must be isolated by ¼ mile from
each other and from any beets that are flowering as well. Barriers such as tree
lines, woods or buildings between varieties may allow for shorter isolation
distances. In the fall, dig up the plants and cut off any leaves about an inch
above the crowns. Transplant into bins of damp sand or sawdust and store at
32-40°F under high humidity. In mild climates chard may survive with protection
outside or in a greenhouse. In the spring, transplant outside 6"-10"
apart in rows 16"-24" apart. Be prepared to stake or trellis the
plants as they can grow to several feet in height. Harvest seed stalks as they
dry and thresh with a flail or by stomping. After threshing, use a ½" and
¼" screen to help with cleaning. Chard seed remains viable for 4-6 years
under cool and dry storage conditions.
