Plant them out asap, make sure you have good rich soil (not too much N though) and water regularly.

Hi there, I have broccoli growing and aquadulce broad beans. Are these compatible? I don’t think these beans climb as much as some others but find it hard to distinguish between dwarf and climbing for these. Thank you!

By the info I provided below and your concern about growing broccoli near beans, you can grow near dwarf but not recommended near climbing. By the sounds of it climbing beans need to climb (twine) up a trellis/pole etc. Broad beans do not do this, therefore I would call BB dwarf beans. JMO.

I suggest you look on an internet seed selling site and look through the different varieties. Try Eden seeds or Boondie seeds (in Australia) or look up NZ websites.

Yes it is to late now, plant out seedlings if you can get hold of them.

It takes about 4 weeks to grow a seed to seedling stage to transplant. And it is time consuming - watering 2-3 times a day. Miss a day or so and the seedlings could be dead. Plant seeds now and it takes about 12-16 weeks to grow to pick. You are looking at July Aug for harvest. I live sub tropical and most vegies do not grow much in July Aug. You are temperate so they will grow less probably. SO you plant SEEDLING this time of the year. A general rule sub tropical and probably temperate (no frosts) is for winter veg you plant late summer and for summer veg you plant late winter/very early spring. I will be picking my first broccoli next week.

Is it advisable to fold leaves over the broccoli head as you do with cauliflower? The heads are still quite small but parts seem to be yellowing.
