Answers to common questions about plant care, landscape design, greening, and drip irrigation from Maghakyan Botanic in Armenia.
Plant watering frequency depends on many factors, such as plant type, pot or soil size, temperature, humidity, and season. A general rule is to water when the top 2−3 cm of soil feels dry to the touch, allowing roots to breathe and preventing overwatering.
The best time to water is early morning. This allows plants to absorb water before the heat of the day and lets leaves dry by evening, which reduces the risk of fungal diseases. Avoid watering during the hottest part of the day or at night
Signs of overwatering include yellowed or wilting leaves, soft or mushy stems, the presence of mold or fungus on the soil surface, and an unpleasant odor from the soil. These signs indicate that the roots are suffocating and unable to get oxygen.
Signs of underwatering include dry, crispy, or curling leaves that may start to drop, the soil hardening and pulling away from the pot's edges, and the plant's overall wilted or lifeless appearance. The plant loses its turgor and becomes limp.
It's best to use room-temperature water. Tap water often contains chlorine and fluoride, which can harm some plants. To remove these chemicals, you can let tap water sit in an open container for 24 hours or use filtered or rainwater.
Water plants until water begins to drain from the drainage holes at the bottom of the pot. This ensures that water reaches all parts of the root system. Remove excess water from the saucer after 15−20 minutes to prevent root rot.
Bottom watering means placing the pot in a saucer filled with water, allowing the plant to absorb water through the drainage holes from the bottom. This is especially beneficial for plants sensitive to water on their leaves or when the soil has become very dry and struggles to absorb water from above.
In hot and sunny weather, plants require more water as water evaporates quickly. In cloudy or cool weather, and during winter, watering frequency decreases. Regularly check the soil to adjust watering according to weather conditions.
Water drainage is the process of removing excess water from the soil. It's important because roots cannot breathe in waterlogged soil, leading to root rot and plant death. Pots with good drainage holes and appropriate potting mix are vital.
Yes, when plants are actively growing (e.g., in spring and summer), they typically require more water. Their metabolism is higher, and they use water more quickly. However, always check the soil, as too much water is still detrimental.
Newly planted plants require thorough and frequent watering to help their roots establish in the new soil. For the first few weeks, keep the soil consistently moist but not waterlogged. Then, gradually reduce the watering frequency.
In low humidity conditions, plants lose water through their leaves (transpiration) more quickly, so they require more frequent watering. In high humidity, conversely, plants lose water more slowly, and watering frequency can be reduced.
To water a severely dried-out plant, place it in a saucer or basin filled with water and allow the soil to absorb water from the bottom until the soil surface is moist. This may take up to 30 minutes or more. Pouring a large amount of water at once can be damaging.
Water runoff is the water that drains out of the pot's drainage holes. It indicates that you've provided enough water to reach all parts of the root system and to flush out excess salts from the soil, which prevents root burn.
A moisture meter is a device that measures soil moisture. Insert it into the soil near the root ball and read the indication. This helps avoid both over and underwatering, ensuring precise and optimal watering frequency for each plant.
Pot material can affect watering. Terracotta pots are porous and dry out quickly, so plants in them need more frequent watering. Plastic or glazed pots retain moisture longer, so they require less frequent watering.
Root rot occurs from overwatering the soil, when roots are deprived of oxygen and begin to decay. Prevention includes proper watering, using pots with good drainage holes, and selecting a well-draining potting mix.

Yes, automatic watering systems (e.g., drip irrigation or self-watering pots) can be very useful, especially if you are often away or have a large garden. They provide a consistent and controlled water supply.
Soil type greatly affects watering. Sandy soils dry out quickly and require more frequent watering, while heavy, clay soils retain moisture longer and should be watered less frequently. A well-draining potting mix is ideal.
If water isn't absorbing, the soil may be severely dried out and compacted. Place the pot in water for bottom watering or slowly water from the top in small increments, allowing each portion to absorb before adding the next. The plant may also need to be repotted.
