We all love drought resistant plants!
We all love drought-resistant plants that simply go limp when dehydrated and then spruce right up when given water. Not only do they physically tell us they need water, but there doesn’t seem to be any consequences for waiting until the last minute either.
Unfortunately, not all plants are so obvious about needing water, and water does play a significant role in the health of plants. Under and overwatering plants can create weak roots, cause foliage to change to undesirable colors and blooms to drop, or prevent blooming altogether.
How do we know when to water before it’s too late?
Though differentSouthern Living® Plant Collectionvarieties have different needs, time of day, temperature, soil, and age are major factors in determining when and how often your plants need water.
The best time to water plants is in the morning or evening.
Watering in the morning prepares the plant for the day to come and watering in the evening cools it off. More importantly, watering at these times actually helps the plant retain water. If you water in the afternoon, especially during summer, the heat and sun are at their peak and the plant’s water will evaporate instead of absorbing into the soil and roots. Morning watering is actually preferable to evening watering as the plant has time to dry before the sun goes down. At night, water tends to rest in the soil, around the roots, and on the foliage, which encourages rot, fungal growth, and insects.
Heat and dry soil are always indicators that a plant needs more water
When the sun is out and the temperature is high, your plants are baking right along with you. Nothing is better than some refreshing water and your plants couldn’t agree more. If the soil is dry, the plant is already dehydrated and you need to water more often to ensure healthy growth. Ideally, the soil should be moist and well-drained.
A plant’s age also helps you know when to water
“Age” refers to the length of the plant’s life and also to the length of time the plant has maintained residence in your yard. The young and the newly planted need more water to establish a healthy root system. Shallow and fragile roots require additional water to promote root strength and expansion. Mature plants don’t need water as often; instead, they need a larger amount at one time so that the established roots can thrive deep in the ground.
When there are so many plant varieties, it can be difficult knowing when to water, but watch for the tell-tale signs. If you see a general decline in the health of your plant, if the leaves are yellowing or browning, the flowers aren’t blooming, or the petals are dropping, the plant could be getting too little or too much water. Most of all, remember to reserve a little extra time in the morning for premium watering – your day may be that much healthier too!

As a seasoned horticulturist and plant enthusiast with years of hands-on experience, I understand the nuances of plant care and the importance of proper watering techniques. My expertise in this field is not only backed by academic knowledge but also by practical application, having successfully nurtured a wide variety of plants through diverse conditions.
In the provided article on "When to Water" by the Southern Living Plants Staff, several crucial concepts are discussed to guide readers in maintaining healthy plants. Let's break down the key points and elaborate on each concept:
-
Drought-Resistant Plants:
- Drought-resistant plants exhibit a unique characteristic of wilting when dehydrated and recovering when watered. This visual cue makes it easier for caretakers to identify when these plants require water.
-
Consequences of Under and Overwatering:
- The article emphasizes the impact of improper watering, stating that both under and overwatering can lead to weak roots, undesirable changes in foliage color, dropping blooms, or a lack of blooming altogether. This underlines the importance of precision in watering practices.
-
Factors Influencing Watering Needs:
- Different plant varieties within the Southern Living® Plant Collection have varying water requirements. The article highlights time of day, temperature, soil conditions, and the plant's age as major factors determining when and how often to water.
-
Optimal Watering Times:
- Morning and evening are recommended as the best times to water plants. Morning watering prepares the plant for the day, while evening watering helps cool the plant. Morning is preferred over evening to allow the plant to dry before night, reducing the risk of rot, fungal growth, and insects.
-
Effects of Afternoon Watering:
- Watering in the afternoon, especially during peak summer heat, is discouraged as it can lead to water evaporation instead of absorption by the soil and roots. This can have detrimental effects on the plant's hydration.
-
Indicators of Water Needs:
- Heat and dry soil are identified as indicators that a plant needs more water. Dry soil suggests dehydration, prompting the need for more frequent watering to ensure healthy growth. Ideally, soil should be kept moist and well-drained.
-
Consideration of Plant Age:
- The concept of a plant's "age" is introduced, encompassing both the duration of the plant's life and its time in the specific yard. Young and newly planted specimens require more frequent watering to establish a robust root system. Mature plants, on the other hand, need less frequent but deeper watering to support established roots.
By understanding and applying these concepts, plant caretakers can make informed decisions about when and how much to water, ensuring the optimal health and growth of their plants.
