croton question

[Jacqueline Davidson]

I recently (about 2 months ago) bought a croton (Codiaeum variegatum pictum)
which looked healthy and well pigmented when I bought it. Now, however, it's
a bit sad-looking: the colours aren't nearly as bright and several leaves
are dying. The dying leaves turn brown and dry from the tip backwards.

I know the plant needs strong sunlight to maintain the colouration, but I
would appreciate any other advice on general care and possible remedies for
its ailment.

TIA
