Does Potting Soil Contain Fertilizer?

Potting soils are mixes of vermiculite, peat moss, perlite, or other components.

If the potting soil you bought has fertilizer included as stated on the packaging, you don't need to add more fertilizer upon initial planting or repotting, since too much can harm the plants. You can add fertilizer later, since it wears off over time.


Does Potting Soil Need Additional Fertilizer?

As we mentioned, check the packaging of the potting soil to see if it contains fertilizer. If there is none, you still need to add fertilizer to provide nutrients to the plants.

The plants need NPK or nitrogen, phosphorous, and potassium to thrive. Some plants also require other nutrients and vitamins to grow healthy and vigorous. Check the nutrient requirement of your plants before buying any product.

Do You Need Fertilizer To Grow Plants?

If your soil already has all the necessary nutrients and pH levels that your plants need to thrive, fertilizer is no longer required.

Keep in mind that nutrients wash away while watering, and your plants absorb them. Adding fertilizer later will be necessary. Know the soil's condition and nutrient level first before applying any fertilizer. You can use a soil tester to perform this procedure.

Is Too Much Fertilizer Bad For Plants?


Too much fertilizer can harm your plants and the environment. Excessive nutrients have a drawback and may even kill your plant.

Over-fertilizing doesn't only occur from adding too much fertilizer but also happens if the soil doesn't drain well. The roots will burn if the water has not flushed out the fertilizer and you continue adding more.

These are the signs of excessive fertilizer:

  • Wilting and yellowing of leaves.
  • Browning of the leaf's tips and margins.
  • Dropping of leaves.
  • Slow growth or stops growing.
  • Burned roots.

How To Treat Over-Fertilized Plants

You can use the process of leaching to treat your over-fertilized plants. Leaching uses running water to rinse and force the salt in the roots and soil away.

Although leaching can help your plants recover and prevent future damage, this process can't fix the damaged part. After cleansing the plant roots, transfer the plant to new, fresh potting soil and cut away the damaged parts to help the plant thrive.

Wait for the plant to recover for at least a month and regrow before feeding again.

Do Fertilizers Expire?

Fertilizer comes in liquid and dry forms. Dry fertilizers contain essential nutrients and do not expire if stored properly. When the fertilizer has insecticide or pesticide, it can last up to four years.

Liquid fertilizers may be organic or non-organic minerals. The minerals may settle at the bottom of the container if not used for a long period of time. Shake it well before using it.

Can You Use Fertilizer After Transplanting?

After transplanting, let the plant adjust to its new environment and wait for 2 to 3 weeks before applying fertilizer.

The waiting time allows the plant to absorb the nutrients from the fertilizer. You can use root hormone powder to lessen the transplanting shock and help maintain the roots' health.
