Miracle fruit, also called miracle berry or Synsepalum dulcificum, is a shrub or small tree that grows about 5 feet tall in cultivation. The berries, when eaten, make anything taste sweet. You can drink pure vinegar right after eating one and it will taste sweet. Miracle fruit requires certain conditions and is only hardy down to USDA zone 10b. This means that the plant will not survive temperatures that drop below 35 degrees Fahrenheit. Knowledge of how to create the right environment will help you produce a healthy plant.
Plant the miracle fruit in a pot filled with a mix of Canadian acid peat and pine bark. A mix of half peat and half perlite also works. This plant needs acid soil and hot weather to survive; potting it is the best way to control the environment.
Place the potted plant in full sunlight when inside. In summer it can sit outdoors in light shade. When indoors, place a tray filled with stones under the plant. Pour water into the tray up to the top of the stones and mist the leaves periodically. This will increase humidity. A humidifier will also work.
Water the plant deeply after planting. Allow the soil to dry slightly before watering again. This plant can easily succumb to root rot, so make sure the soil is never waterlogged.
Fertilize with a water-soluble fertilizer specifically made for acid-loving plants during the hot summer months. Follow the directions on the package for application instructions. Each manufacturer will have different instructions.
