stopping tulip rot

Doug says you can't fight basic biology. And yes, if you plant tulips in an area with summer irrigation, they will indeed fade away.
So - simply accept this fading away - and replant some every year to keep blooms coming.
Or don't plant.
But there is no solution to basic biology and trying to grow a plant (tulip) in a condition where it is simply not suited to being.
Sorry
