This bed has my brassica family of plants. This include, Brussels sprouts, calebrese, cauliflower, pok choi and a small portion of lettuce squeezed in a spare portion.
This is a tight squeeze into this bed. The Brussels sprouts are on the right hand side of the bed. Next in is the cauliflower, and then the main plant on the left hand side is the calebrese ( broccoli) - plus some lettuces seeds and some bolted pok choi.

Bolting Pak ChoiPak choi is a member of the brassica family and although its a little hard to grow (the main problem generally is that it is very inclined to bolt), its worth the effort since the entire plant can be eaten - flowering shoots, leaves and stems.
A key requirement is to place the plants in a sheltered site with soil that is not prone to drying out. PC has shallow roots and will dry out if you dont keep the soil moist. Dig in plenty of well rotted manure or compost before sowing. Sow seed directly in the ground in early summer - sowing earlier than this (in cool weather) is the main reason why Pak Choi bolts. Always keep well watered.
This is exactly what has happened to me. I got young plants back in March and grew them under a cloche for about a month. They have totally bolted ( but at least still edible). I have removed and used about half of them so far - hence the space for the lettuce. But next stir-fry, their days are numbered.
This was the only raised bed I had to add some feed to. A lot of the lower leaves were starting to turn purple which from my internet searches led me to believe a nitrogen deficiency. I used some store bought nitrogen this year, but next year I plan to use some nettles juice( Nettles left soaking for about a month in a bucket of water - note, try to use one with a lid as the stuff stinks from past memory!).
