UPDATE 2018 – Successfully grown in non-circulating hydroponics (KRATKY) and began 3rd generation seedlings trials.
This variety was acclimatized to SG natural environment by 2017.
The parent plants of this variety began their journey on January 16 2016 in soil.
This is Alpine heirloom Pineapple strawberries, a low growing variety with 1 inch sized light yellow colored fruits.
The taste profile of this variety has been described as sweeter than red strawberries, with an unforgettable impact of pineapple and rose.
GERMINATION NOTES
Sowed on January 7 2016 and germinated on the 16, about 9 days.
These seeds were not easy to germinate.
We succeed only on our third attempt.
Germination tests will continue in 2017 to pin down the best method to germinate these wonderful strawberries.
Pineapple strawberries are rarely sold in overseas supermarkets and even Farmers’ marts.
This variety does not travel well.
They have to be consumed the same day as harvest!
How to transplant seedlings post here.
We germinated more seedlings than needed to study how they grow.
In addition, what conditions made them grow better in our natural environment.
We collected these data to craft our strawberries growing technique for our workshops.
They were bigger plants than white strawberry varieties.
At 2 months old, they outgrew PET bottle pots and have to be transplanted to grow bags.
A common problem seen on non-red strawberries in Singapore is cupped leaves.
Seedlings tend to fail more during the second month of growth.
We have observed this tendency in red Alpine strawberries as well last year.
From the 4th month, they became hardier.
Cupped or folded leaves are signs of stress.
On the assumption that cupped leaves may be due to lack of aeration in the PET bottles, we made adjustments with our soil mixes.
The leaves improved after this was done.
Recycling efforts continued this year as well.
Most of our strawberries are grown in PET bottles, either 1.5L or 600 ml plastic bottles.
This year, instead of painting these bottles, we recycled even plastic bags and old socks (suggested by member ” Shy Jean“) to shield them from the heat of the sun.
Cooling with ice packs as shared by member Wanqing’s method was also explored during very warm weather.
As much as possible, we hope to show gardeners that growing strawberries in tropical countries, is possible and with the least carbon footprint and costs.
See why I enjoyed growing strawberries from seeds?
We get the chance to witness each development closely as they evolved.
Just watching how the crown began preparation for its flowering/fruiting journey is amazing. 🙂

Pollinating flowers with new young friends (Jonas and Eva) from NakedGreens‘ gardening group! August 14 2016 –
When pollination is successful, strawberry’s petals will drop completely.
Sometimes, even after successful pollination, the fruit may dry up in Singapore, halting its journey to fruiting.
Thus, we always keep our fingers crossed till harvest day!
Not taking any developments for granted.
The strawberry plant though continued to evolve.
Check out how flowering stems developed from the crown.
HARVEST DAY (Parent Plants to our second generation seedlings to come) – August 7 2016 :)
These strawberries took one month to slowly ripen and grow.
Fruit sizes are about 2.5 cm to 3 cm when it’s fully ripe.
Pineapple candies smell scent in the bedroom!

Second Generation (Born in Singapore Strawberries) – Seeds from our ripe strawberries were sowed for the next generation of pineapple strawberries.
Hopefully, we will have acclimatized strawberry plants for Singapore soon.
As the seedlings grew, we need more space to accommodate an expanding garden.
Thus vertical space was considered again.
A new method to grow them in less soil and using Singapore natural resources work well.
It will be shared in workshop sessions only.

OBSERVATIONS on second-generation plants (February 02, 2017 ) –
- Hardier than Generation 1 , need no chilling treatment
- Slower to flower
- Fruits production is less than parent plants
With so many seedlings on hand, the window of opportunities grew to learn more from them.
For example, what kind of soil is best for strawberries?
Working with soil specialists, we were able to put our seedlings through soil trials in order to pin down a formula that works for these plants in our climate.
Thus, customized ready soil mix is in the pipeline soon,
The learning journey never stops as we sought to learn more about our strawberries.
As these plants are not commonly grown (yet), everything from soil mixes to plant care has to be documented.
After many months of trial and error, we think the solution to the best soil mixes is close.
What do you think of our progress on these 3 months old seedlings?
Another discovery on December 10, 2016 –
Stressed Alpine strawberries even a reputed non-runner variety like this one will sent out runners when they sensed danger.
We do not think this is a good sign for this plant.
The instinct to live is high for this seedling!
Second Generation Strawberry Plants
Recovered from transplant shock very quickly, within 2 days instead of weeks.
Comparative Study of SG vs. USA seedlings –
Since we have seeds from USA Heirloom and SG born Pineapple Strawberry plants, we thought it would be interesting to study how they grow together for a comparative study.
These were our observations so far.
The germination rate for SG seedlings was 4 days compared to 9 days for USA seeds, and as can be observed, the speed of growth is faster for SG seedlings as well.
These pictures were taken on October 2nd 2016.
Seasoned gardeners lend a hand to study how to grow strawberries better in Singapore from February 2016.
Summary of Pineapple Strawberries Information –

Two months old Pineapple Strawberry Hydro “plug-ins” seedlings can be PRE-ORDER.
Due to limited space to grow, reservation is needed.
Thank you for understanding.
Hi
Interested in promoting your strawberry growing techniques in the gardening communities? You are invited to conduct gardening short course in ITE. please call me if you wish to share and spread this passion. Thank you.

Hi ! I was reading your strawberry journey and have been interested in the pineapple strawberry, would actually know where you get the seeds from or if i could purchase some from you ?
Thanks
I will be selling them in my workshops only as there is very limited stock. This variety is not easy to grow without some understanding/experience of strawberries first.
Oh… then is it possible to let me know where you got your seeds from, as i am interested in cultivating them as well. Thanks 🙂
Hi, i have been trying to purchase the same breed of seeds online but i don’t know how i can ship it to SG, would reall appreciate it if you could share the experience, my email is whipandbake@gmail.com . Looking forward to your reply as it would help me alot ! Thanks
Regards,
Alex
Yes, most of these cold season strawberries seeds are not available for sale outside its natural growing zones. Mine were from growers direct who are also friends, and sometimes I wait 6 months for relatives to hand carry back.
