All about Hydrangea

hydrangea 1A lovely shrub for containers or garden beds, hydrangea bloom repeatedly throughout summer. Their colorful, rounded flower clusters make them a useful plant in any container or landscape.

Hydrangea are loved by gardeners, florists and wedding planners as they possess both grace and beauty. Most popular hydrangeas are the macrophylla group, also known as Big Leaf, Florists, French or Garden Hydrangeas. Flower color ranges from blue, purple, red, pink, white, and even green.  They come in a range of shapes, including the traditional Mophead, Lacecap, and Cone shape. Some newer varieties only grow to a few feet tall and wide, making them ideal for containers.

Use Sloat Planting Mix and E.B. Stone Sure Start to get hydrangeas off to a great start. If growing the blue and purple types, use A.C.G. (Azalea, Camellia and Gardenia) soil to keep their color and feed with an acidic fertilizer. Start using true blue or Espoma soil acidifier in the fall to change pink shades to blue and purple shades. They are very easy to grow in partial shade with some morning sun in well-drained, rich soil with plenty of organic matter.

Turn Hydrangea Flowers Blue
Love blue Hydrangea? Early spring is the time to turn their flowers blue! Bay Area soils are normally alkaline, which produces pink flowers. To turn Hydrangea blue/purple they’ll need to grow in more acid soil. We recommend using either Espoma Soil Acidifier or Greenall True Blue; both are easy to use. Time is of the essence though…because once Hydrangeas start growing from their winter dormancy, it’s too late. And with the sunny warm days we’re having lately, the clock is definitely ticking!
