How To Grow Your Own Azalea Bonsai Tree

Azalea Bonsai - Indoor Bonsa TreeThe Azalea is one of the most popular bonsai trees because of its beautiful flowers. Even when the Azalea bonsai is not in bloom, it is a spectacular green since it is an evergreen tree.

There are numerous varieties of the Azalea plant with various shades of red or pink flowers. Some Azalea trees even have white flowers. However, the most popular variety that is recommended by most people and is easily available is the Satsuki Azalea.

Satsuki Azalea bonsai are one of the most sought after species of indoor bonsai regularly available.  These miniature Azalea plants are gorgeous when grown as bonsai.  They produce a large amount of beautiful flowers and are eye catching when in full bloom.  They typically bloom in late spring and are available in any flower color.  Azalea bonsai grow smaller leaves than most trees, making them the perfect choice for a bonsai.

Thinking of growing your own azalea bonsai tree? Let’s take a look at some of the main azalea care considerations.

Watering Azalea Bonsai

Azaleas do not do well with dry soil.  They need to have moist soil at all times, so checking daily is crucial.  Dry roots will shrivel up and die very quickly, leaving you with a dead plant.  Azaleas do not like lime, so use lime-free tap water or rainwater whenever possible.

Placement Of Your Azalea Bonsai

This species enjoys well lit areas that are sheltered from direct sunlight.  They can do well in partial sun if needed, but ensure that the midday sun is filtered.  This tree performs best in diffused light or partially shady locations, which are ideal for producing flowers and keeping a Satsuki Azalea healthy.

Training Azalea Bonsai

When wiring your Azalea, you should use aluminum wire instead of copper.  Aluminum wire, which is softer than copper, is more suitably designed to training Azalea bonsai due to their brittle branches and soft bark.  Wire this miniature tree in November, after the growing season has ended.  This species is typically trained into a semi-cascade, windswept, slanting, or informal upright style.

Repotting Azalea Bonsai

Satsuki Azalea bonsai prefer acidic soils, so using extra peat moss is advised.  Peat moss also helps retain water while still allowing air to reach the roots.  The best time to repot this type of tree is before you see the tree flower.  You can trim a substantial amount of the feeder roots from an azalea.  Do not prune the less prevalent thicker tap roots.  Repotting can also be done later in the season, just make sure to pluck all flowers; you want the tree concentrating on recovery instead of growing flowers.

Fertilizing Azalea Bonsai

Satsuki Azalea bonsai prefer an acidic fertilizer that does not include lime.  Fertilize this bonsai every other week in the spring.  Stop feeding fertilizer while the tree is flowering.  If you forget to stop, new leaves will overpower the flowers. In the late summer and early fall, switch to a monthly feeding of high phosphor fertilizer.

    Hi I wonder if you could advise me as my son gave me a Satsuki Azalea bonsai. I have bad light indoors and have put it under a grow light. It seems to be doing well however I have no idea how many hrs of light it need nor if I should stop the light in winter so it goes dormant. I’d love for it to bloom in spring 😊
