if anything it gets too little sun; our balcony is east-facing, & the
insect house is on the wall that doesn't get any direct sunlight. i'll
try moving it to the other end of the balcony where it gets sun up to
early afternoon in the summer.

great, i'll try the insect attractant. all seeds are proper organic
ones, into organic potting soil, & definitely no pesticides or
herbicides going into the balcony garden, only additives are organic
fertilisers & composts. the city does composting here, so we add our
compost into that (get a voucher for free compost in return).

great - we always have lots of cornflowers, & some other purple ones
that i don't know the name of, plus lavendar. the bees also seem to like
nasturtiums, which we always have plenty of too. i'll look into more
purple flowers.
