Diameter Plants Watering Bulb

The duration depends on the plant's size, the soil type, and the ambient temperature. Generally, the small bulb lasts a few days, while the large bulb can sustain a plant for up to a week or more.

Use the small bulb for tabletop plants or pots under 6 inches in diameter. The large bulb is better suited for floor plants or larger containers that require a higher volume of water.

To prevent soil blockage, wrap a small piece of cheesecloth or a coffee filter around the end of the stem before inserting it into the soil. Alternatively, fill the hole with a bit of potting mix after inserting the bulb to keep it stable.

These bulbs work best for plants that prefer consistently moist soil, such as ferns or peace lilies. They are not recommended for succulents or cacti, which require the soil to dry out completely between waterings.

You can clean the bulb by rinsing it with warm water and a mild dish soap. If there is mineral buildup, a small bottle brush or a mixture of vinegar and water will help restore the glass's clarity.
