raised bed good or bad ideahello there i asked my husband to buid me a raised bedwhich he has done

Wow! That's a big bed, Aina! Are you sure that you have the measurements right? 585 square meters would be 39 meters long, by 15 meters wide. How deep (tall) is it? Ideally, the soil should be close to 1/2 meter deep, which means that you will need 290+ cubic meters of good soil to fill it, which could mean as many as 19 truckloads!

Oops sorry about that meant 0.585 metres square.

A one ton bag is reckoned to be 1 cu metre.
Easier to work it out if you can give us the actual dimensions. Length, width and depth.

Hmm...0.585 square meters would be enough for 3 plants of cauliflower, broccoli, cabbage, bulb fennel, or curled kale. The same area will support 6 plants of Tuscan or Russian kale, collards, kohlrabi, heading lettuce, endive, Swedes, celery, eggplant, and banana peppers. You could squeeze in 12 plants of chard, beets, spinach, rapini, mustard greens, leaf lettuce, bush beans, dwarf peas, mache, full sized carrots, turnips, bok choy, large radishes, and onions grown for size. 24 or more plants of regular radishes, onions, mesclun, baby carrots, arugala, garlic, shallots, and parsley will fit. Hope that this helps with plant selection.

If that is all your veg space I wouldn't try cauliflowers because they aren't the easiest things . In particular they resent any early setback. Also you only get one picking from each plant. With kale you can go on harvesting for ages by just taking one or two leaves from each plant. Same appliers to spinanch - if you grow spinach beet instead you can go on harvesting rather than having to pick the whole plant.

Spinach can bear repeated harvest, as long as you take no more than a third of the leaves at a time.
I have noticed that cauliflower is commercially grown in warmer climates--as a winter crop in my area. I have heard that there are varieties that will produce smaller curds, once the main one is cut, but I have no personal experience with them. Always, the main problem is the room that they take up. Only potatoes and members of the squash family take up more space per plant...one reason that I left them out of my list.

I once tried cauiflowers on my allotment and they were a total failure, which is when I found out what I'd done wrong. The ones on the plot next to mine got totally over grown with grass and weeds when the gardener was ill, and the cauliflowers were magnificent, peeping out from the long grass...

It sounds like the secret to growing cauliflower in the UK is a series of short screen windbreaks, maybe between every two rows, to cut cold winds at either end of the growing season.

Possibly but the neglect was midseason so no cold winds to speak of. Anything's worth a try though, but with such a small growing area something else would give you better returns for your effort.

Oh, yes! Even when they are growing perfectly, cauliflower is hardly worth taking up a small bed like that.
