Signs of Over-Fertilizing

As plants grow, they require occasional nutrient boosts from fertilizer to keep them going strong and healthy. But more is not better when it comes to fertilizing your plants.

As plants grow, they require occasional nutrient boosts from fertilizer to keep them going strong and healthy. But more is not better when it comes to fertilizing your plants.

One way to think about over-fertilizing plants is how overeating affects our bodies. When too much food is taken in, the body (or plant) doesn’t know what to do with it.

Here are some things to look for in your plants that can indicate you’re giving them too much fertilizer:

    t

  • Yellowing leaves. Fertilizers contain salts, and too much can block plants’ ability to take in water.
  • t

  • Excessive foliage. Lots of green leaves with no fruits showing.
  • t

  • Spindly, leggy plants. Too much fertilizer makes the stems grow quickly, before the rest of the plant has a chance to fill in.
  • t

  • Disease vulnerability. Over-fertilizing the soil can kill beneficial microorganisms that protect plants.

Stick to fertilizing your plants only every other week. If you notice signs that they’re getting too much, you can revive them by flushing out the soil with water.
