Juniper tree – The Juniper is one of the three species used as bonsai plants. The Juniperus is a genus with over 50 species of evergreen conifers, plants that come from the forests and hills around the world. The Junipers have two types of leaves: needle-like leaves at a young age and larger leaves in adults. The range of colors of the leaves varies from steel blue to green until the green light, sometimes with shades of silver or gold.
Most species of Juniperus is a classic bonsai for the Japanese who collect them in their mountains and can reach the age of 200 years or more.

  • Shimpaku or Juniperus sargentii: the Shimpaku is a Chinese variety of Juniperus with bright green foliage. It becomes a darker green when ripe. The tree has dense, compact foliage excellent for bonsai. As with many varieties of Juniperus, the foliage may turn into a brown or bronze after frost and remains so until spring, when you return to a more familiar (and healthy looking) green.
  • Juniperus x media Juniper x Media is more powerful than the Shimpaku but has a less well-branched growth. In comparison, the green foliage has a gray-blue.
  • Juniperus Sabina common in Europe and of similar color to Shimpaku. The Juniperus Sabina has leaves more flexible, but more subtle, that require a continuous pinching to support the branching.
  • Juniperus San Jose is one of Juniperus leaves with colors from blue to green and a beautiful red bark. They are more easily in the United States of America.

Notes on the cultivation of bonsai

Do not cultivate the junipers at home; suffer from low humidity and lack of light. They should be watered sparingly as easily suffer from root rot, while the leaves should be sprayed frequently to maintain your pores allowing them to breathe free of dust. Misting also prevents perspiration and excess water loss during hot summer days.

Fertilization of Junipers

Fertilization should be every two weeks. Use fertilizers with very nitrogen from early spring until mid-summer, then fertilized with a balanced fertilizer to the end of the summer, continue using fertilizer nitrogen with little during the winter.

Repotting of Junipers

Repotting should be done in any case in the month of April. Do not repot or prune the branches too early in the year. It can be very successful repotting during the heat and humidity of August, although it should be avoided repotting during the very hot days. Once stabilized in an area of good quality, repot every 3 or 5 years. Since the Junipers cannot have bare roots, you must change more than a third of the land each year.

For a Bonsai Junipers well defined, the entire structure will require a total winding at least once in his life. It takes three months to a year, depending on the thickness and strength of the shoots, in order to see the results of a modeling. During the summer, the wire can leave deep scars suddenly. Signs of light instead will disappear within a few months.

Pruning of Junipers

As with all conifers branches should always have enough foliage or he will die. I Ginepri grow from early April when temperatures begin to rise, and then later produce new shoots that extend throughout the summer until early autumn. The leaves can be pinched or cut and the plant can be modeled throughout the growing season. It is important to thin out the leaves (once or twice a year) to ensure an even distribution of air and light to all the leaves.

Reproduction of Junipers

I Ginepri reproduce easily. To get large logs the aerial part can be buried and rose from May to the end of June when it starts to grow. Cuttings can be taken from April to September.
