Answer: It's normal for Shasta daisy blossoms to dry up and fall off during extended hot weather -- above 90 F for several days. Watering them is not the answer. If you oversaturate the ground, the roots will rot, which makes the problem even worse, especiallyon young plants. Keep the plants healthy by growing them in full sun and by using mulch. Water only when the soil is dry and remove dying flowers as soon as you notice them. Once the heat spell passes your plants will send up more flowers.
