Camellia advice
 

first off, it wasn't flowering, ie the buds stayed buds then dropped
off, so i gave it a bucketful of epsom salts and charlie carp, etc.

it flowered! then the top of the plant started to die, absolutely going
dry, with lots of new growth low down and spreading out sideways.

when i read up it suggested that - i shouldnt have planted cornflowers
underneath it (which i thought was protecting the roots from too much
sun) and that non-budding can be a virus disease from which the plant
doesn't recover.

also on the old growth there is some form of crusty spots that look like
an insect.

should i keep spraying with pyrethrum?
should i move the cornflowers gently now and put cowpoo mulch over the
soil and feed it camellia food?

any help would be greatly appreciated.
