heads). Broccoli matures in spring from sowing made the previous year, whereas calabrese
types matures in mid to late summer from sowings made earlier in the same year.

packets. That way you won't pick the wrong variety.

Message: Hello I've grown purple sprouting broccoli this year and have had a huge harvest. I need advice on how to finish the plant off as it has now come into flower and any broccoli heads the plant produces are quite woody and bitter. Should I cut the plant back or should i let it be? I want to do the right thing so as to have lovely sprouting next year. Any advice would be great. Thanks Jan

I'm growing Italian sprouting broccoli for the first time and I live in New Mexico where the temps are currently reaching over 90 degrees. From what I can tell my plants look healthy, the leaves are hugh but they have not started to flower or produce any broccoli. Is the norm or should I be cutting anything back. The plants have been in the ground for 30+ days. Your help would be appreciated.

Message: After a good harvest last year, I left the purple sprouting broccoli to keep growing; the woody stalk grew to about 4 feet; the few flowerheads that were left developed massed narrow black seedpods. Two green finches discovered them, and working downwards, stripped the seeds out, leaving the pods still attached; wonderful to watch. I have planned six different plots for them this year. So, if you love bird-watching, dont follow the advice below to prevent broccoli going to seed.
