Detailed Guide to Making Hydroponic Napa Cabbage Bonsai
Container: bowl, dish, transparent containers are best!
Hydroponic time: around Spring Festival (late January to early March)
Method: trim the base of the napa cabbage flat, place it directly flat in the container, add an appropriate amount of water and that's it!

Care method:
1. Place on a sunny windowsill or balcony!
Change the water every 2~5 days, and after about 8~10 days it will bloom! After 4~5 days it enters full bloom!
The napa cabbage flowers are golden yellow, and the full bloom period is very beautiful! (It generally blooms fully for 7~10 days!)
And after the full bloom there may still be scattered smaller blooming periods! (Lasting half a month or a month, when sunlight and nutrients from the cabbage head are plentiful!)
Generally, the flowering period of hydroponic napa cabbage can last 20~30 days! Of which the full bloom period is 7~10 days!
2. If artificial pollination is carried out during the full bloom period, you can see the napa cabbage produce fruit!
(Napa cabbage hydroponically grown from mid-February to March is best)
3. After the napa cabbage produces fruit, it takes about a month or more to mature and produce seeds!
The seeds obtained can be directly used to propagate the next generation of napa cabbage seedlings!
(The author has confirmed this through experiments, very certain!)
Appreciation purpose: you can see the napa cabbage bloom and bear fruit!
Golden-yellow napa cabbage blooming, a patch of golden yellow, very beautiful, especially suitable for decorating indoor environments!
Advantages: easy to obtain, the cabbage head can be obtained at almost no cost!
One tip: if you find a napa cabbage head that has already bolted during October~December, you can follow the method and start the process early!
Extension: this method is also suitable for bolting rapeseed (the kind with a relatively large root base!) and bolt vegetable.
