We moved to a house where the previous owner had planted Halley's Comet type tulips (yellow with red stripes). They bloomed beautifully for a number of years but now, over the last two years, they seemed to have lost their red stripe and the yellow is not as vivid. Is there a way to bring back the red/yellow coloring or do I need to plant new bulbs? Is there a way to prevent this from happening again, if I plant new bulbs? Thank you!
