Smart Gardening #1: Study Data Science in Analog Way


Three-way Meter which can be purchased at Amazon can let us measure (1) Moisture, (2) Light, and (3) pH of soil without any battery. Not sure about accuracy. I would like to use this analog meter as a starting point for smart gardening.

When it’s sunny, luminance level when up to 750.

From here on,  I would like to improve the backyard gardening system by taking measurements using my engineering skills and gardening experience and help grow plants efficiently and effectively.

Let’s start the journey begin.

Here is a picture of strawberries from the garden. This is the third year since I started growing strawberries. The number of strawberries is growing exponentially this year.



Backyard Gardening #1: 2019 June Week 1

Here is my gardening update.

Strawberry: In a couple of weeks, we should be able to pick up fresh strawberry from our backyard. This strawberry is 3 years old, so the strawberry crown is big now. There are 1st and 2nd generation strawberry plants.

Japanese Eggplants: It is good to cut the first flower (which I did) so that we can grow the stem and make the size bigger.

Blueberry: Now, lots of green blueberries. Need a couple of more weeks to start eating 🙂

Flower: This smaller one was from last year. It survived over the last winter, which I didn’t expect. Plus, it looks bigger.


Gardening: Strawberry Pollination

Strawberry is a seed plant. To produce berries out of strawberry flowers, we need to pollinate strawberries. There are mainly three ways to do pollination.

1. Insects like bees can carry pollen (outside in spring time)

2. Wind can shake strawberry flowers for pollination (outside or indoor by fan)

3. Touch pistils with cotton sticks or fingers (outside or indoor)

Since it is still before last frost date here in Oregon and I still keep strawberries indoor, today I used a cotton stick to pollinate strawberries. We need try to get pollen from stamens with the cotton stick and then touch pistil. In general, we need to cover the whole pistil area evenly to grow nice berries. Otherwise, berries could become strange shape. The worst case is it turns into brown color, which means that the flower failed to get pollinated.


If pollination is successful, the pistil remains green and it will become a green berry and graduatelly turn red and big. Then, time to taste our own organic strawberries 🙂
