This is a coincidence, I was just looking at my coriander and thought ' I will go onto TAS and ask the best way to harvest the seeds for use in the kitchen- and the 1st topic is about coriander !
I grew a few different herbs 3 years ago in maybe 6" pots, gave a lot away, lost a few but this one coriander in its black pot seemed healthy enough so just left if through the winter in the corner of a small raised bed. Well it survived just fine and started to grow well, I thought it could do with a bigger pot but when I tried to lift the pot the corianders roots were through the bottom and half way to Australia - so I left it where it was.
Looking at it now it is easily 7' tall, people are astounded when they see it, so a word of caution out there , if you grow coriander and it likes the place its growing, buy a pair of steps to harvest the crop. I will see if Eck will put a pic on at the weekend.
I pick the leaves for casseroles and curry and sometime soup though its not soup weather for me really, the hens get some chucked over now and again but not too often, don't want coriander eggs really BUT someone please tell me how to harvest the seeds please.
The 1st flowers have gone over and they have left lots of quite small seeds - do they grow anymore in size ? Do I pick them and ripen on a window ledge or leave them to ripen on the plant ? My coriander is full of flower and I really dont want to waste the harvest like I have in previous years.
