Symptoms of nutrient deficiency

  • Symptoms of nutrient deficiency include yellow leaves and poor growth.

  • Iron chlorosis (leaf yellowing with green veins) is the most common nutrient deficiency. Acid-loving indoor plants like gardenias are prone to this.

  • The remedy is applying a chelated iron product according to the label directions and acidifying the soil using a sulphur product. Look for a product labeled for indoor plants or houseplants.  

  • Fertilizer for indoor plants.
