How to cultivate hydrangeas - TvAgro por Juan Gonzalo Angel

Twitter @juangangel With immense flower heads,hydrangeas flaunt an old-fashioned charm that is hard to resist. Colors also beguile with clear blues, vibrant pinks, frosty whites, lavender, and rose—sometimes all blooming on the same plant! The colors of some hydrangeas—especially mophead and lacecap—can change color based on the soil pH which affects relative availability of aluminum ions. Acidic soils with a pH of less than 5.5 produce blue flowers; soils with a pH greater than 5.5 product pink flowers. White flowers are not affected by pH. Unrivaled in the shrub world, these elegant ladies are easy to cultivate, tolerate almost any soil, and produce flowers in mid-summer through fall (when little else may be in bloom). Hydrangeas are excellent for a range of garden sites from group plantings to shrub borders to containers. Most hydrangeas thrive in rich, porous, somewhat moist soils. Add compost to enrich poor soil. They prefer full sun in the morning, with some afternoon shade; however, many will grow and bloom in partial shade. This is especially true for the bigleaf hydrangeas (see Recommended Varieties below). Plant in spring or fall. Dig a hole as deep as the root ball and 2 to 3 times as wide. Set the plant in the hole and fill it half full with soil. Water. After water is drained, fill the rest of the hole with soil. Water thoroughly. Space multiple hydrangeas about 3 to 10 feet apart.
