I recently built my wife a raised kitchen garden, which is very simply a box
on legs, 2ft.6ins from the ground, so that she can grow some salad crops
without needing to bend. Firstly I have a problem with both carrot fly and
flea beetle,how do I deal with them and do I need to change all the compost
or can I treat it? Secondly, not a problem but a mystery, I have a lot of
worms in the compost. Now bearing in mind the height of the box, how on
earth did the worms get there, as there is nothing but compost straight out
of the bags in the garden?
