Hi Candice,

Here are some tips on how to get a Crown of Thorns plant to Flower.

Learn to identify a Crown of Thorns plant and how to get it to flower .
Crown of Thorns
  1. These plants are sensitive to temperature. A Crown of Thorns plant likes to be warm and does well in temperatures between 60°- 95°F (15.6°-35°C). A Crown of Thorns plant may lose leaves if the temperature goes below 55°F (12.8°C). If the temperature goes below 60°F (15.6°C) it stops the plant from flowering.
  1. Put the plant in very bright indirect lightVery few houseplants should be placed in direct sun. High light refers only to bright indirect light since direct sun often burns the leaves of indoor houseplants. An area that is too hot and dry encourages Spider Mites and causes blooms to quickly fade. A northern exposure really doesn't provide enough light for high light plants. These plants need to be placed directly in front of an east-facing window, within 1-3 feet of a west-facing window, and within 5 ft. of a south facing window. A high light area has over 300 ft. candles of light. but no direct sun.
  1. Feed monthly when the plant is actively growing with a water soluble fertilizerPlants need fertilizer only when they are actively growing. Slow growing plants in low light require very little plant food. Too much fertilizer is worse than not enough. Most plants prefer a water soluble plant food at 1/2 the recommended strength. Plants that are in bloom or dormant should not be fertilized. Houseplant food contains nitrogen (N), phosphorus (P), and potassium (K). A fertilizer containing these elements in equal proportion is considered a balanced plant food. Nitrogen helps in photosynthesis and encourages the growth of leaves and stems. Potassium and phosphorus also help in photosynthesis and aid in root and flower development. Most fertilizers have trace elements of other minerals that are lacking in the soil but are necessary for good plant growth. Fertilizers have a high salt content. If a plant is not producing new leaves and doesn’t absorb the fertilizer, salts build up in the soil. These salts can burn the roots, discolor the leaves, and cause new growth to be small. diluted to ½ the recommended strength. Use a plant food low in nitrogen and high in phosphorous to limit leaf growth and encourage blooms on a Crown of Thorns plant.
  1. When a Crown of Thorns plant is actively growing, usually from late spring to early fall, water well and then allow the top 50% of the soil to dry out before watering again. Reduce the amount of water when a Crown of Thorns plant is not producing new leaves and flowers, but never allow the soil to totally dry out. A Crown of Thorns plant can get severe root damage if the soil gets too dry.
