I'm new here and to gardening, but this year I have tried growing a few
vegs on a small piece of land, which gets nice sunshine, and whilst my
onions and potatoes havn't done to bad, things like radish, beetroot etc
have made lots of top growth but there is nothing underneath them. Also I
have brussel plants about 3 foot tall but no brussells as such on them. My
collies made plenty of top but only very small hearts some of which went a
funny colour.
Could someone please tell me what or where I am going wrong with my veg
growing.

If the land hasn't grown much before then it should be fertile and it sounds
like it gets enough sunshine too. The only other thing that could cause a
problem is watering.

Radish and beetroot, when did you plant them?
Brussels Sprout are a winter crop, check out the seed packet for cropping
months, our's aren't showing sprouts yet and the earliest I've seen crop is
in October/November.
Collis hate any shortage of water or other check to growth, they do make big
plants too, some say they are difficult. Summer ones do tend to get
discoloured with the sunshine and eaten by the caterpillars so we also grow
the winter ones..Walcheren Winter Armardo (whatever) which always produce
nice big clean heads in the early spring.
You can tell when Collis start to heart up, the leaves will start to curl
round at the base slightly instead of growing straight up. Bend/break the
leaves over the curds to keep them covered if they aren't ready, or you
aren't going to cut them immediately, to ensure they stay white.They all
tend to go over quite quickly if not cut and with F1 seed they do all come
at once.
