A few weeks ago I wrote an article concerning signs you are overwatering your plants. It created interest in overwatering, but also sparked interests in the subject of underwatering plants. Since some of the signs of overwatering and underwatering plants look very similar, I am sharing some signs of underwatering.
1. Your plant is wilting
Wilting is a sign of both underwatering and overwatering your plants. In the case of underwatering the plant, when you feel the leaves you will notice they are crisp not limp. Wilting in this case is a symptom of a lack of water passing through the cells of a plant. Plants have pores on the surface of leaves called stoma. They allow air to enter plants. When plants do not have enough water they close their stoma to stop evaporation and this leads to wilting. Remember plants also wilt because of other reasons including overwatering, too much sun, being rootbound, too much fertilizer, or some diseases. Unfortunately, plants can’t talk so we can’t just ask them what’s wrong…or can we?
2. Soil is dry
Eric Santos Division Leader, Irrigation and Water Management at ValleyCrest Companies, is always reminding people a simple solution for testing soil moisture is a long screw driver. Walk your property and press a screwdriver into the ground. When the soil is moist, the screwdriver should penetrate the soil easily. The depth of penetration will vary by the soil type, size of screwdriver, and your strength. As the soil dries up, the screwdriver will be harder and harder to push into the soil.
3. Slowed growth
A slowdown in growth is a sign a plant is not receiving enough water. This can be a temporary or permanent situation. If the plant experiences a temporary decrease in water supply, the growth may just slow for a short period. If the challenge is more permanent you may see new leaf growth being smaller than normal.
4. Foot prints remain visible on turf
Walk across your lawn late in the day and examine the lawn behind you to see if your steps left any “footprints.” Your footprints will appear in a lawn when the grass blades have low levels of water in their tissues. When the grass blades are compressed by your feet, the low water levels prevent the grass blades from springing back up. If your footprints remain for an extended period of time, the lawn should be watered to prevent the grass from becoming dormant or possibly dying.
Once again we go back to the basic of water management. Understanding the signs of overwatering and underwatering are the basics for more sophisticated water management. I’m sure you have a few to add to the list and would love to hear your comments about underwatering.
