If you recently acquired a carnivorous plant, you may be wondering how to fertilize it. Fertilizing carnivorous plants, like other plants, can be tricky. If you do it wrong, you can burn their roots and kill them. According to the Botanical Society of America, carnivorous plants have adapted to living in low-nutrient soil by getting their nutrients from trapping and digesting insects and even small lizards and mammals. For that reason, they need to be fertilized through their leaves and not their roots, also known as foliar feeding.

Difficulty: Easy
Instructions

Things You'll Need:

  • Spray bottle Distilled water 30-10-10 orchid or epiphyte fertilizer Rag
  1. Step 1

    Purchase a good 30-10-10 fertilizer such as Epiphytes Delight, which is highly recommended for most carnivorous plants. Some suggest using orchid fertilizer on Mexican butterworts (Pinguicula) and Nepenthes (tropical pitcher plants) and Miracid fertilizer on North American pitcher plants (Sarracenia), Venus flytraps (Dionaea muscipula) and sundews (Drosera). However, others state that using fertilizer on sundews can fry their leaves. Because of this contradictory information, you will want to watch your plant carefully when fertilizing.

  2. Step 2

    In a spray bottle, dilute the fertilizer with distilled water so it is 1/10 its normal strength. For example, use 1/2 cup fertilizer to 5 cups distilled water.

  3. Step 3

    Cover the soil with a rag. This will protect it from receiving any fertilizer.

  4. Step 4

    Lightly mist the leaves of the plant every two to four weeks during the growing season. Carnivorous plants absorb nitrogen and other nutrients through their leaves, instead of through their roots like other plants.

  5. Step 5

    Feed your carnivorous plant an adequate diet of insects to ensure it gets all the nutrients it needs. For best results, feed them insects that they would find in the wild such as fruit flies and wax worms. Feed no more than one insect per week.

Tips & Warnings
  • Avoid acid-based fertilizers.
  • Applying fertilizer to Drosera schizandra, Drosera prolifera or Drosera adelae can fry the leaves.
