Do hydrangeas flower every year in pots?
The size and type of container you choose will often depend on whether you intend to treat your hydrangea as an annual and keep it in the pot for just one growing season or as a perennial, in which case it will stay outdoors in the container season after season. But hydrangeas are water-loving plants; they prefer moist soil and evolved to live in humid conditions. They also use water to cool themselves off in high heat. These needs are incompatible with the hotter summers and longer droughts that climate change has made our new reality.
What is the best fertilizer for hydrangeas to bloom?
An organic fertilizer formulated for acid-loving plants, such as Holly-tone, is the best choice for hydrangeas that thrive in lower pH soil, including bigleaf hydrangeas, oakleaf hydrangeas, and mountain hydrangeas. Baking soda is mildly alkaline, but it’s a very short-lived solution in the soil. When applied to the ground around your hydrangeas, it will briefly raise the pH in a narrow zone – and then disappear with the next watering or rain.Use soil amendments specifically designed to lower pH, like sulfur or aluminum sulfate, and apply them directly around your hydrangeas.
