Just note of caution with regard to reusing old compost - take care as you
empty the pots in case there are any vine weevils. Sift throught the compost
carefully.
They love to infest pots and eat plant roots. The trouble is with pots there
are no predators to munch on them unlike open soil. Keep an eye open for the
adult beetles too - kill them on sight.
They are nastly little blighters and you definitely don't want to spread
them around.
If you find any in the pots - they are around 1cm long, white with a brown
head and usually curled up into a letter C - any such compost put it into
the dustbin. Do not attempt to reuse it or it will lead to a major contagion
of the things - and no plants, no veg.
