Our first exploration of white strawberries was  WHITE SOUL on August 23 2015 in soil. In 2017, we learned how to grow in liquid base, and began new exploration using KRATKY hydroponics method. This post is a rewrite of the journal from 2015 to compare notes between soil based and KRATKY, non circulating hydroponic. The latter’s setup looked something like this –

 2015 – Germination was very fast, only 6 days. Seeds were sowed on August 23 after freezing overnight and they germinated on August 29.

Not all white varieties germinate within the same length of time (less than 10 days), some varieties were slower, about 14 days. Please check out germination method at this post.

New method utilizing heat and light while balancing with cool in natural environment was developed in 2018 for speedier germination. This method is only taught in our workshops. For most cool seasoned plants, including lavenders, now used the balancing act to germinate.

The germination time was about the same for soil based or hydro White Soul variety. In these observation, the seedlings were very small compared to red varieties.

We also experimented in 2015 whether seeds that had been frozen longer would made any improvement on the speed to germinate seeds.

A second batch was sowed on October 16 2015, after freezing over a month, and they germinated on October 21, 5 days later. Thus, the length of (seeds) freeze did not make much difference.

Whether sowed on soil or other medium, the seedlings are very small and frail compared to the red strawberries.

They are very delicate plants and transplant process was difficult. Young seedlings have very low survival rate when we tried them in 2015. The risk of failed seedlings increased with every transplant. Thus do not transplant too many times.

This variety may be difficult for beginner gardener to attempt. Every stage can be a challenge without prior knowledge of growing them from seeds and how to troubleshoot when symptoms of stress appeared. Much of what we learned from growing this variety formed the formation of our workshop’s curriculum on the challenges and how to resolve them.

The heirloom characteristics of red stem showed by the third week. At this stage, the roots were about 1 cm long.

We transplanted most of the soil based seedlings before the crown developed. The growth rate of this medium was slower than liquid based plants. Among the white varieties, White Soul grew the slowest.

In soil, they often die without warning. The leaves drooped and brown after being transplanted. We learned the most insights by growing this delicate variety.

Wilting Leaves

Seedlings in liquid base grew faster compared to soil based. Knowledge on how to settle the seedlings and hydro nutrients are necessary to grow them in liquid base. Not all nutrients are suitable. Trial and error experiments to get our KRATKY formula right.

In liquid base, they grew faster even without any high technology conveniences. However without prior handling experience of strawberries or/and no hydroponic knowledge, they are difficult to grow.

Hydro – 3 months old

Whether soil or liquid base, this variety remained slow and small compared to red varieties.

They tolerate morning sun and early afternoon heat well from the forth month. More growth was observed from 4th month.


Not heat but rain killed young White Souls seedlings on January 18 2016..

This trial tested whether they could adapt to natural environment without shelter from heat and rain. Thus 30 plants were sacrificed for this test and planted in 60 L of natural compost outdoor.

From pioneer batches of 30 seedlings,

At the height of our hot months, White Soul variety suffered stress from heat. The entire plant drooped like this.

Liquid Base

Removal from stress source will revive these plants. In soil, icing down soil relieved the plants. It is not recommended to grow white soul outdoor.


Our first exploration in 2015, in soil, was not successful. All the flowers dried up and the plants seem in poor health. From this experience, we learned how to read strawberry plants’ signal and what were they telling us before rushing to apply a remedy.

A wrong remedy add more stress to plants already in distress. For example, adding fertilizer can kill.

White Soul leaves like most other white varieties are lighter green and thin texture.

A healthy plant showed open faced leaves and not cupped as illustrated by above picture.


Soil based White Soul enter flowering stage at 8 months, whereas Kratky was 4 months.

Crown Thickening from 2nd month


Typical of white strawberries, White Soul turning into fruits from pollinated flowers took about 3 weeks to fully form.

The first flush of flowers may not turned, thus we learned to prune off rather than keeping on the plant. Trimming off encourage more buds and fruits form better on the next round.

The fruits start oddly shaped and fill up later.

White Soul variety provides a good learning experience for immediate level strawberries gardeners, because they are challenging. Overcoming their constant pitfalls in our natural environment enable us to handle any type of strawberries. Learn about other challenges of growing white strawberries in our climate here!

The plant remained small compared to other varieties, but fruit production can be vigorous.

Grow Mizuna ミズナ, 水菜, Beni HOUSHI

Whether its soil or liquid based, this mizuna is easy to grow and quick to harvest. It is very delicious to eat as salads or cooked.

The variety that we grew at home is call Beni Houshi, a purple stem mizuna that is very popular in Japanese restaurants.

Added to salads, the purple hue of its stalk adds color and vibrancy as well as being high in anthocyanin, an antioxidant property found in blueberries.

The general rule of thumb for anyone who loves kale and want fresh harvest regularly is to grow 3 to 4 plants per family member.

Grow your own at home saves money, as this is a cut and grow plant. As a gauge, a 10 weeks old plant will yield 5 big leaves every week. Cost to grow this super food can be as little as $1 per week or zero if we have our own compost.


Additional perks as home growers are we get to decide when to harvest, whether younger more tender leaves or the bigger foliage from more mature plants. In any case, own grown is always best, as we grow them without harmful pesticides and there is no waste. We only harvest when we need to and how much from the plant. When parents grow, children learned as well.

Learning and being able to grow superfood is a blessing. We are always grateful there is available healthy whole food at home when the weather is bad, and there is no need to dash to the supermarkets. Having these instant fresh salads also mean that we are very conscious of what need to be harvested, thus increasing the chances of healthier options for our meals.

Last but not least, there is NO carbon footprint from our gardens to mouth ! 🙂 

However, space may be a major constraint to grow enough of these wonderfully delicious and nutrients packed greens for urban high rise dwellers like ourselves in Singapore.

To solve space challenges, I chose to grow in PET bottles with Kratky’s non circulating hydroponic instead of soil to save space.

STEP 1 – Germination Method

It is important to keep seeds moist at all times. They can be sowed on wet tissues and lightly covered with another tissue. Cling wrapped or ziplock in bag to maintain moisture on seeds bed.

Germination speed is faster on tissues (2 days) than on soil (9 days).

STEP 2 – Transplanting Seedling

After a few days, the seeds will show 2 leaves (called seeds’ leaves or cotyledons ) like the following picture. The third leaf is called true leaf and carried the characteristics of future mature leaves.

Seed Leaves showed

Transplant seedling when true leaves (the second pair of leaves) emerged and about 4 cm long. At this stage, it need more sunlight.

Tip – For speedier seedling’s growth, keep grow lights on longer while maintaining moisture with foliage misting.

In Hydro – Make sure roots reach nutrient feed.

In Soil – kept moist and seedling is upright.

STEP 3Adjusting Sun Exposure

For better tasting kale, where leaves are tender and less bitter, adjust sun exposure when seedlings are one month old.

Grow in morning sun which is not hot or remove from direct afternoon sun to grow in partial shade, made better tasting leaves.

Cut bigger or outer most leaves stem as close to main stem as possible.

Keep younger smaller leaves on the plant until they grow bigger, usually within 10 days.

Cut and Regrow Leaves

After harvest, the cut parts will not regrow. The stem will continue to grow taller while the harvested area remained bald. Thus, cut the leaf stalk as close to stem as possible to reduce waste. Only the higher mid section will regenerate new leaves.

Harvesting Kale

When Kale are harvested young, less than 2 months old, leaf stalk and leaves are more tender. To find the texture and taste preferred, we encourage tasting as the plant grew. There is no right or wrong time to harvest, as Kale can be enjoyed as microgreens or mature. For raw salad, we preferred the less bitter and tender leaves of less than 2 month plants.
