How Do I Know When to Water?
Lee-Anne FerrariShare
It’s the most common question we hear from new and seasoned plant lovers alike: “How often should I water my plants?” The truth? There’s no one-size-fits-all answer. Melbourne’s changing seasons, indoor heating, plant type, pot size, and even your light levels all play a part in how thirsty your plants are. Learning when to water isn’t about sticking to a calendar—it’s about learning to read your plant’s needs.
In this blog, we’ll break down simple ways to tell when your indoor plants need water, how Melbourne conditions affect your routine, and how to avoid the number one killer of houseplants: overwatering. Plus, we’ll show you where to find the healthiest Melbourne indoor plants and care advice at The Grow Centre.
Why a Watering Schedule Doesn’t Always Work
You might have heard advice like “water once a week” or “twice a month.” While this can be a loose guide, watering on a strict schedule is one of the easiest ways to accidentally drown your plants—especially in Melbourne, where temperatures and humidity can shift dramatically across seasons.
A better approach is to check the soil, observe your plant’s behaviour, and consider your home's environment.
Signs Your Plant Needs Water
Here’s how to know your indoor plant is ready for a drink:
🌱 1. Check the Soil
Stick your finger about 2–5cm into the soil. If it feels dry at that depth, it’s usually time to water. For moisture-loving plants like ferns or calatheas, aim for slightly moist soil. For succulents and cacti, wait until the soil is completely dry.
💧 2. Look for Wilting (But Check Carefully!)
Soft, drooping leaves can indicate underwatering—but they can also mean overwatering. If the soil is dry, it’s likely your plant is thirsty. If the soil is wet and the plant is still wilting, hold off—its roots may be waterlogged.
🪴 3. Feel the Weight of the Pot
Lift the pot when it's dry, and again after watering—it’s a great way to learn what your plant feels like when it needs a top-up.
☀ 4. Consider Melbourne’s Climate
During winter, indoor plants in Melbourne slow down their growth and need much less water. But in summer or when heating is on indoors, the soil can dry out faster—so adjust accordingly.
Common Watering Mistakes
-
Overwatering: It’s easy to kill with kindness. Always check before watering.
-
Using cold tap water: Especially in winter, this can shock the roots. Room temperature is best.
-
Letting water pool in saucers: Empty excess water after 15–20 minutes to prevent root rot.
