Frequently Asked Hydrangea Questions
What About Hydrangeas As Gift Plants
During the Easter season, the garden centers are filled with gorgeous hydrangeas. These plants make great gifts, but DO NOT TRY TO PLANT THEM IN THE YARD AFTER THEY STOP BLOOMING. These bigleaf hydrangeas are commonly forced by nurserymen in pots for spring bloom. `Ayesha' is not hardy enough for outdoors in many areas, but makes a good container plant. Also called the `lilac hydrangea', its blossoms resemble lilacs and even have some fragrance.
Why is my Hydrangea looking so wilted, when the soil is still moist around it?
Hydrangea leaves and blossoms may look very stressed and limp during the heat of the day; if the soil is moist, and they recover by early next morning, they are simply responding to high temperatures or hot sun.
