turnips in which crop rotation?

[janeyo]

Hi with which group do I put turnips for crop rotation?
I have 6 beds = a) carrots parsnips b) potatoes c) onions and leeks d) caulis & brocolli e) peas and beans and f) misc, to include sweetcorn, lettuce and odds & sods

thanks

ps just thought they are root veg so should go with carrots & parsnips?

I think they are brassicas .

[Paul Wagland]

They certainly are Carl, as are radishes, horseradish and various types of mustard.

The Brassica family is quite an important one to get right in terms of crop rotation, as club root is a real problem on some plots.

There are flowers in this group too - stocks and honesty being the only ones I can remember!

Right, so they go with the caulis (that surprised me, good job i asked or they would have taken their chances with the carrots!)

ps just out of curiosity, as horseradish can go mad in the garden can I put it in a pot? If so how big?

[Paul Wagland]

I've never had a problem keeping horseradish under control, but if you're worried then planting into a terracotta pot would be a good idea, burried in the ground with just the rim above the soil (helps it stay moist, which horseradish likes). About 30cm width is a minimum I would say, perhaps aim for 45cm if you have space.

If I put it in the raised bed and not in a pot will it have to be moved each year under the crop rotation rules? If I keep it in a pot will it keep longer? or be easier to move?

I grow it in a perennial veg bed, so it doesn't move other than when I lift it to divide (and therefore harvest) the roots. This is a bit outside my crop rotation scheme - if I ever have problems with disease I think I will simply pull it all out and start again somewhere else. Probably lower down the plot, where the ground is more damp.

And wallflowers.............and weeds as well including fat Hen!

Yeah do beware of them Brassica, too many of them for my liking .

The Brassicas are Cauli, Cabbage, Broccoli/Calabrese, Purple Sprouting Broccoli, Brussel Sprouts, Kale, Swede, Radish, Turnip, Kohl Rabi and most of Oriental leafy vegetables like your Pak Choi, Japanese mustards and loads more. One easy giveaway is the seeds, all Brassica seeds more or less look the same, like mustard seeds and all Brassica seedlings therefore look similar too, be careful not to get them mixed up like I have .

I've got Nine Star Perennial caulis which I'll have to do this with as it's a short lived perennial brassica which supposedly crops for three or four years..........we shall see!
