The general rule of thumb for anyone who loves kale and wants 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 superfood 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, our 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 means that we are very conscious of what needs 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.
Small net cup like these supported each seedling in their individual or shared reservoir, and recycled plastic bottles at the same time.
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 a 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.
Transplant seedling when true leaves (the second pair of leaves) emerged and about 4 cm long.
At this stage, it needs 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 the nutrient feed.
In Soil – kept moist and the seedling is upright.
Behind the scene of a local documentary (Go, Go, Grow) part on how to transplant these seedlings into hydroponic sponges.
STEP 3 – Adjusting 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 for better-tasting leaves.
STEP 4 – HARVESTING
Cut bigger or outermost leaves stem as close to the main stem as possible.
Keep younger smaller leaves on the plant until they grow bigger, usually within 10 days.
After harvest, the cut parts will not regrow new leaves.
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 midsection will regenerate new leaves.
When Kale is 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 a raw salad, we preferred the less bitter and tender leaves of less than 2-month plants.
Eating well at home can be as simple as this, adding freshly harvested Kale to cheeseburgers.
We encouraged our daughter, my niece and their friends to harvest vegetables for their meals whenever they want, all over our apartment, on our D.I.Y (Do It Yourself) vertical gardens.
It’s always an unusual play date activity for their friends, as most do not garden or cook at home.
CUT and GROW BACK PLANT
I love how mobile my vegetables “garden” is, that they are all grown in jars and PET bottles. in natural sunlight and feed.
Garden to table in a minute when we harvest our salads!
ADDITIONAL KALE VARIETIES –
SCARLET, RED, GREEN CURLY, TUSCAN KALE –
SCARLET Kale showed its purple tint early.
The seeds took about 6 days to germinate, thus a tad longer than other Kale varieties ( 3 days).
A startlingly beautiful colored Kale!
Can you see the purple?
The edges of the leaves and stem were purple.
RED RUSSIAN KALE
RED Russian Kale has a reddish tint on leaves from the one-month-old seedling.
TUSCAN KALE
Seeds viability is good, about 90% germinated within three days.
Newly sprouted seedlings were yellow in color.
How the seeds progressed within the day –
Some seedlings were planted in liquid and others in soil-based to compare the rate of growth.
It was observed to be faster in liquid base.
All spare containers at home were recycled to grow food in liquid using net-cups or soil in vertical hanging gardens.
BLACK TUSCAN KALE
The color of the mature leaves is a unique blue tint!
Can you see it?
These young seedlings started out looking normal, the blue only appeared in the second month.
The seeds germinated in 5 days and grew rapidly.
When we ran out of space at home to grow them, we made a tower like this out of PET bottles!

Notes on KALE
- Likes moist , well drained and loamy soil
- Grow in partial shade if there is too much sun
- Temperature over 27C or under strong direct sun will turn leaves bitter and tough
- Seeds to harvest is 70 – 90 days , estimated height 10 inches tall
- Harvest big (outer facing) leaves and the plant will regrow new leaves from the middle. The lower stem will have no new leaves
- Young kale leaves are best for salads
- Older leaves are usually cooked or baked
- Hardy biennial plant (2 years to complete its life cycle, to bolt , to decline)
- Belongs to cabbage family
HYDROPONIC to SOIL
This experiment showed that hydroponic kale can adjust to soil environment gradually and thrive.
Other hydroponic plants such as above purple Pak Choy died very quickly.
Another hydro kale transplanted to soil adapted well after a month.
Kale Benefits
- Most nutrients packed vegetable (Vitamin A, B6, C, K, Manganese, Calcium, Magnesium, Copper, Potassium)
- High anti-oxidant (beta carotene, quercetin, kaempferol)
- Lowers cholesterol, reduce heart disease
- Zero Fat
- Protects eyesight
- High Fiber content
Delicious Juice Recipes
- Pineapple-Kale-Blast (Prolific Juicing) – 8 Kale leaves with stem, coriander, Pineapple, half cucumber and 1 medium apple
- Simple Kale – Kale leaves, lettuce, cucumber, lemon, apples (adjust sweetness with apples)
- Kale + Coconut Juice (Alan Tan, urban farmer)
- Green Goddess (Prolific Juicing) – 8 Kale leaves, 2 cups spinach, 12 strawberries, 1 lime, 2 apples, mint, optional – ginger
Kale goes very well with citrus fruits in salads and we love them for light breakfast any day!
We prefer to harvest young Kale leaves (less than 2 months old) instead of waiting till its bigger.
Growing our own Kale means we decide when to harvest to suit our preference.
Hi where did you get your kale seeds from?
Hi,
Kale seeds are harvested from our communities’ gardeners. Its $5 per pack of 30 seeds. Its not posted for sale as supplies are limited.
Hi, this is inspiring! I adopted a little kale plant from my urban farmer friend. It’s been 3 months and my baby kale is growing fine (tiny, but healthy). But, because there’s only one of it, I get only 2 leaves each time (while leaving the young leaves to grow out) I try to harvest. Wondering if there’s a way to do duplicate more of the same plant from what I have. So I have a little kale garden to harvest from instead of one lonely plant. Can you share your experience?
If it’s in soil, very mature plants can be propagated by stem cutting. There are videos of how to in YouTube. But I still prefer to grow from seeds for the fresher taste of young plants.
Hi!
For germination, kale seeds need wet tissue and keep them in a warm & dark area? Or warm & bright area? Is the above method suitable for all types of kale? Hope u can help me, thankU so much!
Hi, very wet tissues in dark warm place
How do I purchase the kale seeds?
Just go to SHOP and contact me from there? Let me which varieties you like –
