6 Signs You Are Over Watering Your Plants


Over watering plants is one of the biggest issues I see in landscapes today. When plants don't look healthy it is tempting to give them more water and often this is a mistake. A mistake not easy to diagnose because in many instances too much water mimics the signs of too little water. Below are six signs you can easily recognize to determine if you are giving your plants too much water.

1. Your plant is wilting but it looks like it has plenty of water

The roots of  plants take up water and also oxygen to survive and thrive. Overwatering, in simple terms, drowns your plant. There is space between the particles of soil in your garden. Oxygen fills this space. Soil that is constantly wet won’t have enough air pockets and plants will not be able to breathe by taking up oxygen with their roots. When this occurs, your plants will wilt (giving the appearance of too little water) even though the soil is wet. Here is a great video from our friends at Denver Water about the negative side effects of too much water for your plants.

 


2. The tips of the leaves turn brown

One of the quickest, first signs of overwatering to observe occurs at the tip of the leaf.  If the tip of the leaf is turning brown this is a sign of over watering.

3. Leaves turn brown and wilt

Leaves turn brown and wilt when plants have too little and too much water.  The biggest difference is too little water will result in the leaves feeling crispy when you hold them in your hand.  Too much water and the leaves will feel soft and limp in your hand.

4. EDMA

When roots of plants absorb more water than they can use,  water pressure begins to build in the cells of the leaves. The cells will eventually  burst, killing them and forming blisters and these areas will look like lesions. Once the blisters erupt, tan, brown or white warty growths begin to form where the blisters originally were. Plus you will see indentations forming directly above the growths on the top sides of the leaves.

5. Yellow leaves

Stunted slow growth with yellowing leaves is a symptom of over watering.

6. Leaf fall

Leaf fall occurs in both situations of too much water and too little water.  When both young and old leaves are falling prematurly combined with buds not opening, this is a sure sign of too much water. Check your soil regularly.  Don’t be afraid to push you finger into the soil and see how moist it is an inch or two down.  If the soil is moist and you have some of the conditions above it’s a sign to reduce your water.  Also, many stores sell inexpensive and accurate moisture meters.  You simply insert them in the root ball and they will tell you how much water is in the soil.  This is a simple and inexpensive tool that will take much of the guess work out of watering your landscape.  I hope these tips are helpful and please share a few of your own in the comments area below.

Thank you very much for this article. I have a large garden in Morocco (am a retired Brit. Ex-Pat) and I now realize some plants have been overwatered when I thought more water was needed.
I hope most of it can be revived OK.
Sincerely,
Peter
