This is my first time growing broccolis. My broccolis started to have very small bluish head and then they started to get more yellow without getting "big enough" (as compared to the broccolis I have bought so far). Should I wait for them to grow further or just harvest them as small as they are?
I am in Chile, so we are in late winter here, the days are getting warm and sunny.
You need to get them before they start to unbunch like the second picture as it's going into flower. The reasons you aren't getting large flowers are many, but probably not enough nutrients, or water in the ground. And since they're a cool season vegetable they tend to bolt like this in the heat.
You don't say where you are and it depends on location on what time to best plant them so that they don't bolt before they're ready for harvest.
Yeah, these broccoli plants are 'bolting'. What fertilizer did you use? This is found when too much nitrogen is added, lots of vegetative growth and the reproductive growth bolts. OR, when there are a few too many days of drastic temperature changes, up or down, that will cause this 'bolting'.
The most common problem is too much nitrogen in relation to Phosphorous and Potassium. Adding raw compost for example.
Harvest when small, they will be delicious. Check your fertilizer program. What has been happening with your weather? What soil is in these raised beds? How were these raised beds made? What have you added in terms of compost, chemistry? I've never seen such healthy broccoli leaves...that tells me you've used too much nitrogen. Let me know okay?
