A Sure-Fire Way to Force Blossoms on Orange Trees


According to Texas A&M University, oranges are native to India, but were spread throughout the world along trade routes. The Spanish first brought oranges to North America. They are widely grown in the tropical and subtropical climates of Florida, Texas and California. On orange trees, fruit production is preceded by fragrant, white flowers. However, if an orange tree is stressed or not getting sufficient light or nourishment, it will not produce blossoms. Fortunately, there is a method for forcing blossoms on an orange tree.

Step 1

Place the tree in a window or beneath grow lights. Orange trees require at least six hours of light to produce blooms.

Step 2

Water the tree whenever the soil becomes dry to the touch. Oranges prefer moist, well-drained soil, but do not tolerate standing water. Soil should feel like a wrung-out sponge, but should not feel like a saturated sponge.

Step 3

Fertilize your orange tree once a month with a balanced (20-20-20) liquid fertilizer. Mix the fertilizer with water according to package directions in summer and dilute it by half in winter.

Step 4

Withhold water from an orange tree until the leaves curl up. Then water the tree. This will force the orange tree into dormancy. The flowers should appear on the tree within a month after this.
