The miniature orange tree, also known by the name Calamondin, is a tree that is valued more for its ornamental properties than for its ability to bear fruit. The tree can grow between 6 ½ and 25 feet high. In some parts of the country it is grown as a hedge or on patios, rooftops and balconies for its white blooms and the bright contrast of its yellow fruit against the green foliage. The tree produces up to five new flushes of growth each year. If given the right growing conditions, the tree can bloom after each flush of growth for almost continual blooms year round.
Wait for the tree to mature. Trees can be started from seeds or rooted cuttings, but will not produce fruit or flowers until after their second year.
Place your tree near a window to ensure that it receives maximum sunlight. Calamondin trees need at least 6 hours of sun to thrive and produce flowers.
Supplement the natural sunlight that the tree receives with a plant grow light to ensure that your plant receives optimal levels of sunlight.
Place the tree outdoors during warmer months. This will help the tree to receive more natural sunlight as well as attracting pollinating bees and butterflies.
Water your tree once every 10 days. Wait until the surface inch of the soil is dry before watering. Never over-water the miniature orange tree.
Fertilize every 5 weeks during the winter months using a balanced liquid fertilizer diluted to half-strength. In the spring, place a slow-release fertilizer in the soil and increase the liquid fertilizer to full strength. Fertilize with liquid fertilizer every 4 weeks during spring and summer months.
Force the blooms by giving the miniature orange tree a resting period. To do this, withhold water from the plant until the leaves become wilted and roll up. Then resume watering the plant. The tree will immediately produce a flush of new growth and will be in full bloom within 2 months.
