Jacaranda Flowering Indoor Bonsai (Jacaranda mimosifolia)
 

Also know as Blue Jacaranda, Black Poui, Green Ebony, Brazilian Rose Wood, or as the Fern Tree; this sub tropical tree is native to South America. Today it can be found all around the world due to its beautiful long lasting Blue-purple flowers.
Its bark is pale grey- brown in color and straight-grained. Compared to other species, the bark is rather thin. The wood is often used for small carving such as bowels.
The flowers appear in clusters; blooming in spring and early summer. Flowers are followed by woody seed pods, containing flat winged seeds. The interesting shapes of the pods make them popular for gathering to make Christmas decorations and for use in other dried floral arrangements.
Outdoors, Jacaranda is evergreen only in the warmest, wettest climates (does well in Southern Florida & Southern California); Hardy in U.S.D.A. Zone: 10 to 11 in the ground it can withstand occasional temperatures down to about 20 degrees F; as a Bonsai it should not be exposed to freezing temperatures.
We consider Jacaranda an Indoor Bonsai in most of the USA because it will be deciduous outdoors, in various degrees, in areas with cool falls & winters or in areas with long dry periods; it won't tolerate long periods of freezing temperatures. If you summer outdoor, it should be brought inside well before the first frost. It can be grown indoors all year as long; it will need bright light and warmth to bloom.


How To Take Proper Care Of Your Indoor Bonsai Tree
Bonsai is the reproduction of natural tree forms in miniature. This art form has its origin in Japan and China where it has been practiced for centuries. Bonsai are grown in pots and are totally dependent on you for their care.
With proper care, your bonsai will remain healthy, beautiful and miniature for many years to come. Since your bonsai is a living miniature tree, it will increase in beauty as it matures through the years. The instructions below are just the basics and, therefore, we recommend that you purchase one of the many fine books available on the subject.

PLACEMENT SUMMER

The Jacaranda likes full sun; it will thank you for putting it in the brightest, sunniest part of your yard or your sunniest window. Jacaranda loves sun and hot weather and consistent moisture.

PLACEMENT WINTER
Once nightly lows begin dipping below the 50 degree mark; it is time to prepare to bring your bonsai inside. The ideal indoor location is on a window sill facing south. An east or west exposure is second best. A northern exposure will work, but will necessitate the use of "grow lights" to provide sufficient light to keep your bonsai healthy. Four to six hours of bright sunlight per day should suffice. If you can provide more light, that is even better.

WATERING

The watering of your Bonsai must never be neglected. Apply water when the soil appears dry; never allow the soil to become completely dry. If your Bonsai in full sun, you may need to water once a day. This schedule may vary with the size pot, type of soil and type of Bonsai tree you own. Evaluate each tree's water requirements and adjust your watering schedule to accommodate it. If you are unsure, it would be a good idea to use a moisture meter until you get to know the requirements of your Bonsai tree.
Watering should be done with a watering can or hose attachment which dispenses water in a soft enough manner not to disturb the soil. Water should be applied until it begins running out of the holes in the bottom of your pot. A good rain is usually a sufficient watering.
Caution should be used to make sure the bottom of the pot does not sit in water. Indoors misting is also appropriate.

HUMIDITY

During the cold months, when your bonsai is inside, we recommend placing it in a shallow tray filled with a layer of gravel with water added. This provides extra moisture around the tree as the water evaporates and reduces the amount of moisture lost to modern heating systems.

FERTILIZING

Fertilizing is also necessary if your bonsai is to remain healthy and beautiful. Since your bonsai is growing in such a small amount of soil it is necessary to replenish the soil's supply of nutrients periodically. Any general-purpose liquid fertilizer will do fine and is available at most garden centers. We suggest that fertilizers be used at half their recommended strength. Fertilizer should be applied at least once a month except during winter. Your bonsai will also respond well to foliar feeding, with a water-soluble fertilizer applied every other month as a spray.

TRAINING

This brief explanation of basic care does not cover training. Training deals with the art of bonsai and should be thoroughly understood before undertaking -- or left to a professional. However, most of the true bonsai trees you find have already been through their training period, thus requiring only periodic trimming & pinching to remain miniature.

TRIMMING & PINCHING

Trimming and pinching keep your tree miniature. Pinch and trim back the new growth to the farthest safe point. Never should all of the new growth be removed. A little should be left to sustain the health of the tree. Tropical and sub-tropical trees used for bonsai will require periodic pinching and trimming throughout the year. Since different trees grow at different rates, it is necessary to evaluate each tree’s rate of growth and adjust your trimming and pinching to accommodate it.

REPOTTING

Repotting must be performed periodically on all bonsai when their root system has filled the pot. The reasons for repotting are to supply your tree with fresh soil, and to encourage a more compact root system. As a rule, most deciduous trees require repotting every two or three years, while evergreens only need to be repotted every four or five years. Since trees grow at different rates, this schedule will not always hold true, therefore, you should examine your tree's root system each year to determine if it has become pot-bound.
In most cases, the potting process is easy and safe if performed properly and at the right time of the year. Repotting should be done in mid-summer. The tree, along with all of its soil, should be removed from the pot. The outer and bottom most fourth of the tree's root mass should be removed. This is done by raking the soil away, then pruning back the roots. In most cases, it is not good to prune back more than one fourth of the tree's root mass. After this, the tree can be placed back in its original pot or into another. The pot should have screen placed over the drainage holes. Then a thin layer of small gravel is placed in the bottom of the pot for drainage purposes. On top of this gravel is placed the new fresh soil. Place a layer of well-draining soil which is sufficient enough to elevate the tree to its previous height in the pot. After placing the tree back in the pot, the area left vacant by the pruned root mass should be filled in with fresh soil. This fresh soil should be worked in around and under the root mass in such a manner as to avoid leaving any air pockets. After repotting, your bonsai should be thoroughly watered. This can be achieved by submerging the entire pot in a tub of water. Moss or other ground covers can be used to cover the surface of the pot to help prevent soil erosion when watering.

INSECTS & DISEASES

Since your bonsai is a tree in miniature, it can be treated for insects and diseases the same as any other tree. If you discover any insects or diseases, visit our website where you will be able to obtain the necessary products to eliminate the problem.
