Use the Right Amount of Fertilizers

Using the right amount of homemade fertilizers on your Pothos plants is essential. However, using too much or too little can cause problems. Follow the directions for each fertilizer recipe. Remember, your plants may need different amounts based on light, potting soil, temperature, and humidity.

Look for Signs of Over-Fertilization

Even if you use the best fertilizer available, too much can hurt your plants. Watch for these signs:

  1. Leaves are turning yellow, brown, or looking burnt.
  2. Plants wilting, even with enough water.
  3. Lots of foliage is falling off.
  4. Plants are not growing well.
  5. Damaged or rotten roots (root rot could also be from lack of drainage holes).

If you see these signs, use less fertilizer or apply it less often.

Fix Nutrient Imbalances

If your pothos has nutrient problems, do these things:

  1. Look at the plant’s signs to determine which nutrient is causing trouble.
  2. Change the type or amount of fertilizer you use based on what you find.
  3. Rinse the soil with water to remove extra nutrients. Let the plant recover before using more fertilizer.
  4. Keep a close eye on your plants and change your fertilizer routine as needed.

Store and Handle Homemade Fertilizers Safely

To keep your homemade fertilizers working well and safe, follow these steps:

  1. Put fertilizers in airtight containers with labels that show what’s inside and when it was made.
  2. Keep fertilizers away from sunlight, heat, kids, and pets.
  3. Use clean containers and tools when creating and using homemade fertilizers to keep out harmful germs.
  4. Throw away any leftover or old homemade fertilizers the right way. Follow the rules in your area.

So, there you have it. These organic fertilizers will do the trick if you want to avoid traditional pothos fertilizer (liquid slow-release fertilizer with a balanced n-p-k ratio).
