Nine Star Perennial Brocolli

Hello,

Last year i've sowed nine star seeds for the first time. I planted some of them and this year they're sprouting. They al have a main brocolli head and some even have small shoots on the sides. But when do i harvest the main brocolli head, how big does this type get ? I added a picture. I'ts about a small fist in size.

Thanks in advance for the help!

 

Hi, they should get heads about tennis ball size, from memory, on a mature plant. If you leave them then you can get a dozen or so heads of that size form on a plant bit in good soil, perhaps quite a bit more.
