advice

[Tarragon2017]

With regard to my first pic should I start thinning out the choy sum how many choy sum should I put in a 1 litre pot.

with the second picture as you can see I am using a large seed tray is it possible to growm them like this and if not how should I transplant.

Advice would be warmly welcome

Choy Sum is a variety of Pak Choi and doesn't much like being transplanted. They make quite big plants - a 1 litre pot is not going to be big enough. If you look at the seed packet it will probably tell you to sow in rows 16 inches apart and thin the plants to 10 inches apart. A standard 1 litre pot measures about 5 inches across. My advice would be to sow a few seeds thinly in a bigger pot, or you could try transplanting some when they have 2 true leaves - try to disturb the roots as little as possible. Any you don't plant out can be eaten in salads as microgreens - I often grow choy sum for exactly this purpose as I don't really have room for it in my garden.

I don't know about the basil in the tray - I grow basil in small pots for the windowsill.
