Q.Tulips in pots
My pots are in the garden. I have read and understood that I leave the Tulip bulbs in the pot and let the foliage die, then I have put the pots in a cool dry place. I want to leave them in the pots to be placed by the front door next year. So when do I bring them out again into the weather, I am in NZ and it is a temperate climate. We are lucky if we see 2 frosts in winter. Thanks
You will need to provide chilling for Tulip Bulbs in the fall for them to have a chance of flowering again.
