Sometimes with broccoli you will get some side shoots that have little heads on them...I would say that if you don't need the garden space, then leave them to see...me...I always need the space for a new plant...Cauliflower I can't remember if it does or not...

Most cultivars of broccoli will set a couple of cuttings of side shoots if it is cool enough. Cauliflower is a one shot plant. Neither tolerates heat, but summers in Maine are pretty cool and should be cooling down so you should get more broccoli. We can only get broccoli or caulilower in May- June and again in late November - January.

I let mine go to seed last year. Never had to plant any this year, ha.

g'day matthew,

with broccolli it will grow more heads though they will be smaller and smaller at each pick but still very tasty i get up to 8 picks before i pull the plant.

with cauliflower no when you cut the head off pull the plant and tuck it under the mulch to break down and feed the soil.

cabbages will also grow little growths about the size of brussell sprouts.

Sideshoots from my broccoli amount to over 90% of my harvest. The sideshoots may be a little smaller during high temperatures but regain size when cooler nights return. You can usually pick those side shoots until nightime temperatures drop into the mid twenties.

Size of those sideshoots is more of a factor of variety difference. I never let them flower since I harvest weekly after the primary heads form and any missed shoot is cut off with the harvest.

Not all varieties of broccoli have good side shoot production. Be sure you're growing a variety that does so that you don't waste growing space waiting for something that won't happen. You can pull the plants, add some compost and plant something else.
