Challenge Question #3
We think the date that tulips are planted this fall will affect the date that they emerge and bloom next spring.
Some of us think that if the bulb is planted later in the fall, it will emerge later in the spring because it needs the same amount of sunlight over time and time to grow roots, stem, and leaves so it can get food.
It all depends on weather says Justin. If it's all cloudy, sure it will get rain water, but if it rains a lot the bulb might die because it could drown! If it was sunny and hot for the whole time, it might dry up all the rain, and then it wouldn't have any rain so it couldn't grow. Caroline thinks temperature has something to do with it - like in fall we get less sunlight and it is colder and in spring we get more sunlight and it is warmer, it's like two different growing seasons.
James thinks if the bulbs are planted in the spring, they might still bloom, but a lot later than they're supposed to.
To test this idea, we could plant a tulip garden in the fall when it is supposed to be planted and plant another one later. We could plant one in each season, and see which one would emerge faster.
