Mastering Plant Hydration: Are You Overwatering or Under-nourishing Your Greens?

In the world of horticulture, watering is one of the most crucial aspects in keeping your plants thriving. Whether you're tending to indoor or outdoor greenery, understanding each plant's unique watering needs is key. Here's a guide to help you water your plants effectively.

Firstly, it's essential to know the signs of overwatering. Overwatered plants may show no new growth, have drooping and/or yellowing leaves, and may harbour pests or mold. If you notice these symptoms, it's likely that your plant is receiving too much water.

To ensure your plants are getting the right amount of hydration, test the soil moisture level by putting your finger about an inch deep. If the soil is not dry, hold off on watering. When you do water, start slowly to avoid overwatering. Watering should be done evenly, as the roots pull from all over the soil.

Room-temperature water is recommended for houseplants, as hot or cold water can damage them. Misting the foliage of indoor plants is acceptable, but avoid pouring water directly over the leaves to prevent potential issues. Outdoor plants can use cold water from a hose, but it's better to spray them indirectly rather than directly.

Different plants have different watering needs. For instance, plants such as the water milkweed (Phyllanthus fluitans) require soft to moderately hard water with a pH between 6.0 and 7.5 and a water temperature of 20 to 28°C for optimal growth. Succulents like Echeveria gigantea prefer slightly alkaline conditions due to their natural limestone substrates, favouring well-drained, mineral-rich substrates rather than specific water quality.

Some tropical plants and hydroponic systems need carefully controlled water quality, including pH and mineral content, for best results. Impatiens and begonias, for example, need consistent watering. On the other hand, cacti can survive with watering once or twice a month.

Seasonal and dormant watering schedules should be considered. When a plant is actively growing, it requires more water, typically in spring and summer months. Conversely, when a plant goes dormant, it requires less water. Plants, including air plants, require water to survive, but when they go dormant, their watering needs decrease.

Lastly, it's important to research the specific watering needs of each plant. Regular tap water is suitable for indoor plants, but avoid using distilled water as it contains no nutrients. Each plant should come with instructions on how often and how much to water it. By understanding your plants' watering requirements, you'll be well on your way to a lush, green home.

Happy planting!
