Black Specks Over Petals And Sticky Leaves Indoor Primrose

Question

Purchased a yellow primrose from supermarket 3 weeks ago, all fine, on sunny windowsill but last week or so tiny tiny black specks appeared on some of the petals, the leaves are a bit spotty and holey, but sticky!

Answer 1

Stickiness usually indicates honeydew, which is produced by insects such as scale and aphids. Treat your plant with Neem oil and see if that helps.
