I have a pot 16 inches

Question

The bulbs should be ok for next year, yes? I put 8 bulbs in a pot 16″ across and 12″ deep. Should I add fertilizer too ?

Answer 1

Tulips are normally treated as annuals in South Carolina so you don't need to fertilize. Plant in November or December for best results.

If you didn't mulch your containers go ahead and do that. They should be fine outside.
