Thank you for sharing. 40 years ago, farmers from Knutsford started growing Chinese Choi sum and Bai choi for super markets. Before that we could not even get gingers or spring onions unless from the Chinese stores.
If you have success in growing Choi Sum, you must share, I have not met anyone growing them like those in HK. Otherwise everything else is easy to grow.
What can we find in the supermarket in UK? Potato, carrot, cabbage, onion, spinach, kale, bean, lettuce and pea..... not more then 12 items. not much green leaves are available. Tomato, corn, sweet potato are original from South America and tones of Chinese greens from China make them open their eyes wide. They never see that before. UK people are not farmer, they are the fighter. Beside vegetable, UK people only enjoy fruits such as apple, orange, pear, grape and banana. Their piece of land and weather is not allow them to plant. Poor region.
