Watering Tools: Cans & Moisture Meters
Watering correctly is one of the most important—and most challenging—parts of houseplant care. The right tools can make the job easier and help you avoid root rot or crispy leaves.
Choose the right watering can
- Long‑spout indoor cans direct water to the soil without splashing foliage. Look for a narrow spout and a comfortable handle for precision watering.
- Small decorative cans hold less water but fit nicely on shelves; they’re great for tending to a few small plants at once.
- Detachable rose or shower heads provide a gentle sprinkle for seedlings and delicate foliage.
- Collapsible or flexible watering cans save space in small apartments.
Do you need a moisture meter?
Moisture meters measure soil moisture through a metal probe and display a reading on a dial. They can help you gauge when to water, especially for larger containers where the surface may dry while the root zone remains wet. However, you can often achieve the same results by:
- Using the finger test: Insert your finger an inch or two into the soil; if it feels dry, it’s time to water.
- Trying the chopstick method: Push a wooden chopstick into the soil; if it comes out clean, the soil is dry.
- Lifting the pot: Compare the weight of the pot when freshly watered to its weight when dry; light pots need watering.
If you do use a moisture meter, insert the probe halfway between the plant and the edge of the pot. Avoid leaving the probe in the soil long term; clean it between uses to prolong its life. Remember that readings are relative, so learn how your plants respond rather than relying solely on numbers.
Other useful watering aids
| Tool | Purpose |
|---|---|
| Spray bottle | Mists foliage to increase humidity for ferns, calatheas and air plants |
| Watering syringe or bulb | Allows precise watering at the base of small succulents or terrarium plants |
| Self‑watering spikes | Regulate moisture for a few days (see our self‑watering planters guide) |
Combine good tools with careful observation, and your plants will tell you when they’re thirsty.
