Want to start your
own seedlings at home to transplant them into the garden? And, do you wonder how
to grow these ‘starts’ and bedding plants
organically?
If so, read on! Here is your step-by-step
guide. First, note that you cannot officially call these bedding
plants “organic” unless you certify each variety as Certified
Organic under the USDA National Organic Program with paperwork,
inspection, and fees. Unofficially, you can grow them happily and
effectively in the spirit of the organic tradition by your choices
of seed, potting mix, fertilizers and containers.
Seed Selection
First, make a list of
the vegetables, flowers, and herbs you want to grow. Ask experienced
gardeners which ones will grow well in our cold soils and short,
cool growing season. Then list how much of each kind you want. Now
imagine these plants full-grown and figure how many will fit the
garden space you have. For example, one cabbage takes nine square
feet of area and a mature head of romaine lettuce takes a square
foot.
Next, buy your seed
from store seed racks or from seed catalogs. In Anchorage, the seed
racks at Alaska Mill & Feed and Natural Pantry offer many brands in
addition to Denali Seed. In Palmer, Budget Feed store will not only
mail your order to Johnny’s Selected Seeds for you, but also waive
the shipping cost of your seed order.
I like seed catalogs
that offer detailed information about growing, the number of seeds
per packet, germination temperature, transplant spacing, etc. A few
of my favorites are:
Johnny’s
Selected Seeds,
www.johnnyseeds.com
Seeds of Change,
www.seedsofchange.com
Nichols
Garden Nursery,
www.nicholsgardennursery.com
Fedco,
www.fedcoseeds.com
Why? Because these
businesses are not corporate giants. They have a policy for
preserving biodiversity, supporting sustainable agriculture,
offering organic choices, and do not knowingly sell
genetically-engineered seed.
Now you have choices
to make! Here’s how to navigate through those options of seed, soil,
fertilizer and containers.
Variety Selection
Treated or Untreated
Seed?
Treated seed is
coated with a fungicide and/or insecticide. How do you know? Look
for specific wording or an alert written on the seed packet. Also
check the seed color. Treated seed is usually (but not always) dyed
pink. The safer and organic choice would be untreated seed.
Open-pollinated, Hybrid, or Heirloom?
Open-Pollinated
(OP) seeds are non-hybrid plants. Pollination occurs by uncontrolled
natural agents such as bees, birds, and wind. The resulting seeds
produce plants just like the parents; thus, OP seeds are appropriate
for seed-saving.
Heirlooms are
open-pollinated cultivated varieties which were once commonly grown
in home and market gardens. There is no rule about how old a plant
variety must be to be called "heirloom", though these varieties are
often 85 years or older.
Hybrids are
denoted in catalogs by F1 and F2. Plant
breeders create hybrids by controlling cross-pollination of parent
plants to increase characteristics such as disease resistance or
yield. Hybrids are perfectly acceptable for organically certified
growing. Indeed, hybrids should not be confused with genetically
engineered (GE) seeds (an organic No-No!). Hybrids are not
appropriate for seed-saving, because the next generation will be
genetic throw-backs (rather than being like the parent plants).
Soil or Potting
Media Selection
Most conventional
potting media are soilless mixes that use Canadian peat as a main
ingredient. These also include a chemical wetting agent and are
often sterilized. Sterile media leaves your seedlings vulnerable to
disease-causing microorganisms (such as “damping off” disease) that
lurk in your propagation area. You want some compost in your mix to
provide beneficial microorganisms to protect your seedlings from
disease. Compost also supplies a wide range of balanced nutrients
and retains moisture well. Choose a potting medium that contains a
portion of compost. Or, simply add one part compost into three parts
of your conventional medium.
Two excellent Alaskan
choices of potting media are Fishy Peat (provided you mix in some
perlite) or Alaska Earth potting medium from Anchor Pt. Greenhouse
(907-235-7288). These are composted from fish waste, seaweed, and
local peat.
Fertilizers
Conventionally-raised
seedlings are fertilized regularly with a drench of soluble chemical
fertilizer. This practice can build excessive salty levels in the
root zone, discourage beneficial soil life, and force-feed the
plants whether they need those nutrients or not.
With organic methods,
your compost is your fertilizer as well as your disease protection.
Compost is an excellent food because it gently nourishes your plants
with a natural, balanced, steady release of nutrients. If your
developing plants seem to need more nutrition than the compost
supplies, choose fertilizers like manure tea or compost tea and
administer a weekly drench or spray. Or, purchase liquid fish and
seaweed fertilizers, and follow the directions. Never over-dose
your fertilizer applications!
Containers
Commercial growers
start with new black plastic cell packs and flats every year.
Instead of using brand new ones, start saving and re-using 4-paks,
6-paks, and flats. Also consider substituting cell packs with yogurt
and cottage cheese containers with drain holes. Or, if you want to
skip the plastic in any form, order a soil block maker and press out
soil cubes into your flats. Soil blocks handle well, and you avoid
container fuss and storage space.
Okay, you are ready
to sow your seed, identify each kind with a marker, and place your
flats in a warm place. As soon as you see the slightest germination,
get them under shop lights for 14 hours per day. The lights must
nearly touch the baby leaves to prevent spindly growth.
Water every day as
needed. By mid-April, you may have enough daylight to transfer your
seedlings from shop lights to a sunny windowsill, but be sure they
don’t fry there. A week before transplanting your starts to the
garden, get them used to UV sunrays and wind by exposing them to
direct sunlight for an hour the first two days, and two hours for
another couple days. Gradually increase exposure up to four hours.
Now your babies are toughened up and ready
for living outdoors in your garden! That is, as soon as your soil is
warm enough—probably around Memorial Day. Congratulations! You
have successfully gotten your hands into the soil, and enjoyed the
satisfaction of growing your bedding plants organically!
