Signs of Underwatering Trees or Overwatering Trees

Signs of Underwatering Trees or Overwatering Trees

Trees can’t tell us when they’ve had too much to drink–or when they’re dying of thirst.

Instead, trees leave subtle clues that we need to decode. Look at your tree’s leaves, and let’s solve the mystery!

Is your tree getting too much, not enough or just the right amount of water?

 

 


The Difference between Overwatering and Underwatering Trees

Signs of Underwatering Trees

Signs of Overwatering Trees

  • The area around the tree is constantly wet
  • New growth withers before it’s fully grown or becomes light green or yellow
  • Leaves appear green but are fragile and break easily

Is your tree getting too much water or not enough?

In both cases, the trees can look eerily similar. Luckily, there are two ways you can determine once and for all if your tree needs more or less water.

  1. Quick and easy check: Stick a long screwdriver into the soil below your tree. If that’s hard to do, your tree needs more water.
  2. Precise-as-can-be check: Below your tree, dig 6-8 inches deep and grab a handful of soil. Your soil should be cool and moist. If it’s sopping wet, you’re overwatering. If your soil isn’t drenched or sandy, roll into a ball. If it crumbles, your tree needs more water. Poke the soil ball a few times. If it doesn’t budge, you probably have clay soil.

How to Fix or Save Overwatered Tree

If your tree has too much water, it’s struggling to breathe. That excess water commandeers spots air pockets previously held. So, your tree roots are getting too much water and not enough oxygen. That’s a double whammy that could lead to root rot, fungi or long-term tree stress.

Here’s how to fix an overwatered tree:

  1. Stop. Don’t water your tree for a week or two. Before watering again, do the screwdriver test mentioned above. Only water your tree when it needs it.
  2. Fix. If you have clay soil, mix in compost to help it drain better.
  3. Inspect. After it rains, see if there’s water pooling around your tree and find out where it’s coming from. Is water running downhill and landing at your tree’s base? Does your rain spout empty right near your tree? If you spot an environmental cause like this, it may be best to move the tree entirely.
