Tulips in cold weather
I have lots of tulips that have grown to full size, with more that are still growing, but they're refusing to open up and bloom. I think this is because we're still in this cold spell, which is set to last for another week or more.
Is this likely to shorten the amount of time I'll see flowers for when the temperature finally rises? It'd be a shame if I get two days of open flowers and then the petals fall off!
