Digging through soil for veg

Hi,

I'm going to be attempting to grow my own veg this year for the first time. I'm growing from my own garden, adapting the space we already have.

I have some raised beds previously containing box & roses which have been dug out. The soil isn't very good quality. It has a fair amount of rocks etc. I plan to add new compost on top, but how far down should the 'good quality' compost go?

In this particular space I plan to grow sweetcorn, brussell sprouts & cauliflower.

Thanks in advance for your help.

If you have already dug the land over to a reasonable depth then just incorperate the compost in the top spit.

Sweetcorn are quite shallow rooting, so you'll be fine.  Brassicas like really firm soil, so you'll need to tread the soil down before they go in.

What kind of space are we looking at? Both sprouts and sweetcorn can get quite large!

For the raised beds that are already built they're approx 2 ft in wide & run the length of the garden which is around 80ft. I will only plant 1 row deep in these for brussels, and cauli maybe 2.

Sweetcorn I know should be planted in blocks so I'm creating a new area for those.
