To soak or not to soak…that is the question (?)

The ecological relationship between seed and soil is like a symphony; there are natural cues that promote germination.

One of the major cues is moisture level! When the conditions are right, the seed will follow its own instinct and begin to swell. Once the seed coat is soft and moist the new seedling erupts into life.

The germination time for seeds varies greatly depending on the species. Some seeds can take years for germination (peonies) and others germinate in less than three days (cabbage family). We can use a mechanical force to speed the germination time (soaking).

Large seeds with hard coats (sunflowers, honeywort, peas, beans, corn and sweet peas) will appreciate a longer soaking- up to 24 hours.

Larger seeds with softer coats such as pumpkins, squash, chard, beets, nasturtium and cucumber are perfect to soak overnight.

Small seeds like lettuce, radish, carrots and tomatoes can become mushy and sticky if soaked too long (15-30 min) is appropriate.

Find a shallow bowl, place your seeds and top with water. Set away from pets, kids and spouses out of direct sunlight and in a warm location. Warm water is best but any water will do (what would nature do).

Once seeds have soaked and swelled…it is time to plant! Follow your seed packet guidelines for planting depth or reference our write up: https://seedsandsoilorganics.com/…/seed-starting-simply/

When in doubt…ask the question: What would nature do?

Alaska Sown-Alaska Grown

What zone are you in? Above frozen ground..

The USDA has a tool that outlines annual extremes for minimum temperature across 13 areas of the U.S.

An example of a zone represented in Southcentral Alaska is zone 4.

The USDA map has minimum temperatures of -30F to -20F for zone 4.

We can use this zone tool to help guide us when adding perennials (plants that live more than two years) and biennials (plants that complete their lifecycle in two years) to our garden spaces.

If I am shopping and find a “zone 7” plant , I may be able to grow this plant as an annual but the rate of overwinter survival will be less as the minimum temperature for a “zone 7” plant is 0F to 10F and the minimum temperatures in zone 4 may be way too cold for this plants survival without certain extreme protection measures.

When we are discussing annual plants (those plants that complete their life cycle in one year) we need know our frost free dates. This is the span of time where we can reasonably expect not to have killing frosts (28F and below).

For my landscape and microclimate growing spaces this is from May 1 (ish) – Sept 30 (ish). As nature doesn’t always fit in the “box” we can expect seasons to extend and sometimes shorten.

Nature is dynamic…not static

Certain plants can withstand much colder temperatures and overwintering with meticulous care of the soil, the enhancement of natural microclimates and a keen understanding of individual plant species coupled with extensive season extension. Taking growing risks is a fun garden challenge I look forward to every year.

We can use these tools as a guide to direct us towards plant choices and landscape design. Check your zone for perennials and biennials and know your frost free dates for annuals.
