Q.Dipladenia plant
It is bushy & looks real healthy but hasn’t bloomed this summer. I have it planted in a big well-drained pot in bright sun and water frequently. This is its 2nd summer. I winter it over in our garage. I fed it liquid fertilizer about once a month. It was loaded with blooms last summer. Could it be root bound in the 14″ pot? We live in Iowa, where my summer flowers usually thrive.
