Fear not, as this article provides practical guidance on how to distinguish between the two, ensuring your plants get the right amount of hydration they need to thrive. Understanding the signs of Overwatering and Underwatering is essential for the health and well-being of your garden plants. In this article, we will decode these signs, help you diagnose whether your plants may be getting too much or too little water, and of course, address how to fix these common irrigation issues. Read on to become a more informed, confident gardener and maintain a more vibrant, healthier garden.
Overwatering vs Underwatering Symptoms Cheatsheet
Overwatering Symptoms:
- 💦 Yellowing leaves with soggy texture
- 💦 Mold or fungus growth on plant or soil
- 💦 Foul odor from root rot
- 💦 Slowed or stunted growth
- 💦 Wilting, even when soil is damp
Underwatering Symptoms:
- 🌵 Dry, crispy leaves or leaf edges
- 🌵 Drooping leaves that don't regain turgidity
- 🌵 Browning or withering of leaves
- 🌵 Slow growth or lack of new shoots
- 🌵 Older leaves shedding prematurely
Only 20% of plant problems are due to underwatering, while 80% are caused by overwatering. Finding the right balance is crucial for plant health and self-sufficiency.
Overwatering can lead to root suffocation and reduce oxygen availability to the plant, resulting in decreased nutrient uptake.
On the other hand, underwatering can cause drought stress, impairing the plant's ability to photosynthesize and utilize nutrients efficiently.
Remember, it's essential to provide adequate water based on your specific plant's needs and environmental conditions for optimal growth and health.
What happens when you underwater a plant?
For this example, we’ll use an outdoor herb, but the principles of how plants are affected by too much, or too little, water will apply to all plants. When you water a plant too infrequently, the leaves begin to yellow and droop. The plant’s roots are also affected by this, so the plant may show signs of being weak and malnourished. If you continue to under-water your plants, the roots will begin to die, and the plant will not grow new leaves to replace the ones that are wilting. The wilted leaves will curl or turn brown and crispy at the edges. This is a great example of how a plant should be waterlogged. Waterlogged means that the soil level is above the surface of the leaves, so the roots are not affected. If you water a plant that is not waterlogged enough, the roots are still wet, so the plant will grow new leaves, but it will be weak. This is under-watering.
What are the signs of underwatering a plant?
If you’ve under-watered a plant, the leaves will be yellow and droopy. If you overwatered a plant, the leaves will be limp and wet. In either case, you will see the slight curve in the stem. If you continue to water a plant that is not waterlogged enough, the leaves will yellow, droop, curl and eventually die. Eventually the wilted stem will die too. Underwatering is less severe than overwatering, but it can still be a problem.
What happens when you overwater a plant?
Overwatering is just as bad as underwatering, but in reverse. The plant’s roots are too wet, so the plant will be weak and not grow new leaves like it should. If you continue to overwater a plant, the roots will rot and die, and the plant will simply wilt and die. This is a great example of how a plant should be waterlogged. Waterlogged means that the soil level is below the surface of the leaves, so the roots are not affected. If you water a plant that is not waterlogged enough, the roots are still wet, so the plant will grow new leaves, but it will be weak.
What are the signs of overwatering a plant?
If you’ve overwatered a plant, the leaves will be limp, yellow and almost lifeless. If you under-watered a plant, the roots will be dry and brittle, so the plant will be weak and wilt. In either case, you will see the slight curve in the stem. If you continue to water a plant that is not waterlogged enough, the roots will be waterlogged, so the plant will grow new leaves, but it will be weak. This is under-watering. If you continue to overwater a plant, the leaves will be limp and yellow, and the stem may be brown. If you continue to overwater a plant, the plant will die.
What is the difference between drainage and irrigation?
Drainage refers to the ability of soil to drain properly and take away excess water through the root zone. Irrigation refers to the ability of water to reach the root zone of the plant. There are several different irrigation systems. The most common is the drip irrigation system. It’s easy to install and use, but it’s expensive. The next best system is the soaker hose, which is the least expensive system. If your soil has good drainage, you don’t need to add any chemicals or restrict how much water you use. The water should drain quickly and the root zone should be no higher than a few inches below the surface of the soil. You can add compost to improve the soil’s drainage. When cleaning your sprinkler, be sure to remove all the dirt and debris. Clear out the sprinkler head and make sure there are no obstructions that may be blocking the water from reaching the root zone.
Don't forget about drainage
What are the signs of poor drainage?
If your soil is constantly wet, it will not allow water to drain well. You will see puddles around your plants or in between the roots. If your soil has poor drainage, the soil will be soggy and the roots of your plants will be waterlogged. You will want to amend your soil with sand or potting soil to improve the drainage. You can also add a layer of gravel or rocks to help prevent excess water from sitting in the soil profile.
How can you prevent poor drainage?
Add compost to your soil. You can purchase or make your own compost from leaves, grass, and other organic materials. This will improve the soil’s drainage and allow water to soak into the soil, rather than sitting on the surface. You can also create a raised bed. This will allow the water to drain out of the soil profile and prevent excess water from sitting on the surface.
