Planting Information

We suggest when planting your newly purchased Nikko Blue Hydrangea plants that you dig a hole twice as wide as the root system but not deeper. Depending on the quality of your existing soil you may need to add a locally sourced compost or topsoil to the back-fill soil. We do not recommend using straight topsoil or compost as a back-fill soil because more times than not these products will retain entirely to much moisture and will cause the root system to rot. Adding compost or topsoil will help the young feeder roots of Nikko Blue Hydrangea to spread through the loose, nutrient rich soil, much easier than if you used solely the existing soil which more times than not will be hard and compacted. The most common cause of plant death after transplanting is planting the new plant to deep. That is why we do not recommend planting in a hole any deeper than the soil line of the plant in the pot. A good rule is that you should still be able to see the soil the plant was grown in after back-filling the hole. Bio-tone starter fertilizer is a great starter fertilizer that provides plants with mycorrhizae fungus. It is a naturally occurring beneficial fungus that colonizes on the new growing roots of plants. It creates a barrier between the roots of the plant and fungus and pathogens that can cause root rot. We love this product and use it on all plants we install in our own gardens. Bio-tone is a gardeners best friend and can help guarantee your success.

Additional Information

History and introduction of Hydrangeas:

The hydrangea was first cultivated in Japan, but ancient hydrangea fossils dating back to 40-65 million years ago have been discovered in North America. Hydrangeas didn’t appear in Europe until 1736 when a colonist brought a North American varietal to England. The oldest fossil finds were found in North America , namely in Alaska , Oregon and California , they were dated at 40 to 65 million years ago , more recent discoveries in China , Japan , Taiwan and the Philippines prove that the Hydrangea have been on this planet long before the arrival of men . In China and Japan they already cultivated Hydrangea's many thousands of years ago , in North America the medicine men used the roots of H.arborescens as a means to drive out kidney stones and to combat bronchitis. The first Hydrangea arborescens ( North American species) was introduced in England around 1736 from Pennsylvania by Peter Collison. Grovonius gave the plant in 1739 in his work " Flora Virginica ' for the first time the name: Hydrangea . The still famous botanist Carolus Linnaeus , to whom we owe our current plant name system ( binomial nomenclature ) has mentioned already in 1753 the name Hydrangea arborescens . The name hortensia , in Belgium , the Netherlands and France still commonplace, was first used by Philibert Commerson , botanist and plant collector, who found some Hydrangeas in Chinese gardens ( 1767 ) and it took to France , he named the plants: Hortensia opuloides or even Hortensia hortensis . Hydrangeas from Japan Since 1639 it was forbidden for foreigners to travel around in Japan, the only contact was by the island of Dejima in Nagasaki Bay and it was here that Carl Peter Thunberg , a pupil of Linnaeus , settled in 1775 and succeeded to acquire five hydrangeas from the mainland, he later called these plants : Viburnum macrophylla ... Sir Joseph Banks brought in 1788 a Hydrangea from Japan with him and gave it to Kew Gardens , he called the plant: Hydrangea hortensis ... Doctor and botanist Philipp Franz von Siebold succeeded around 1823 in two trips to the Japanese mainland and toke numerous plants with him. Thanks to his good work in the eye clinic and the gratitude of the patients , he managed to acquire many new plant species ( Hydrangeas ... hostas , ) When he was expelled in 1829 , for allegedly spying for the Russians , and had to leave Japan, he brought with him various kinds , including H. Involucrata , H. anomala ssp . petiolaris ( climbing hydrangea ) , H. Hirta , H.paniculata ..... Partly due to independance war between Belgium and the Nederlands in 1830 , when he arrived in Antwerp harbour he had to leave behind, 260 plants, bulbs and tubers in the botanical garden of Ghent . Around this time ( 1830) the Hydrangea macrophylla got its present botanical name : Hydrangea macrophylla . Plant hunters seek new varieties. Around 1879 the famous English nursery Veitch , sent the plant hunter Charles Maries to China and Japan , he would find two hydrangeas and bring back , a Hydrangea with flat flowers (lacecap) he called H.macrophylla 'Mariesii' and a spherical type , he called Hydrangea macrophylla ' Rosea' . Around 1860 the Russian botanist Carl Johann Maximowicz was sent out by the Tsar of Russia to Japan to discover plants and he would eventually bring more than 400 plants to the gardens of St. Petersburg , later in 1867 he published his Revisio Hydrangearum Asiae Orientalis . Species such as Hydrangea. anomala , H.aspera and H. heteromalla were introduced during the 19th century in Europe, thanks to two enthusiastic botanists , namely Francis Buchanan Hamilton and Nathaniel Wallich . While nurseries from Asia , U.S. and Europe in the course of the twentieth century brought mainly numerous cultivars of Hydrangea macrophylla on the market , enthusiastic planthunters and botanists went out in nature discovering new species. From Belgium Robert and Jelena de Belder brought along lots of seeds of numerous expeditions , which were brought to growth and later subsequently crossed. In France, Robert and Corinne Mallet devoted themselves with great enthusiasm , to the genus Hydrangea and after so many expeditions founded the Shamrock collection in Varengeville - sur-mer (Normandy) and released numerous interesting books and publications Hydrangeas such as Hydrangea Sweet Summer are primarily used for landscaping because their petals contain low levels of cyanide, making them unfit for consumption. The exception is hydrangea serrata which Buddhists drink in a sweet tea as part of a cleansing ritual. The tea is said to help treat autoimmune disorders as well as malaria, kidney stones and enlarged prostate. In Western culture the hydrangea has many different uses. Native Americans used the root as a diuretic and the bark as pain relief specifically for muscle pain and burns. Traditionally, hydrangeas are also a polite way of telling a suitor you are uninterested. Now they are beautiful garden decoration that line many houses in suburban America. The etymological meaning of hydrangea stems from the Greek words for water, hydros and jar, angos. The name comes from the constant moisture required to keep the flowers happy, healthy and blooming. In Japan, they are said to be a sign of apology or gratitude because an emperor gave them as apologies to his maidens. To the opposite effect, hydrangeas have a negative sentiment in Europe where they were used to declare arrogance. They also became synonymous with frigidity in the Medieval ages because it was believed that young women who grew them would never find husbands we however do not believe this.
