The Fertometer measures the level of nutrients in the soil of your potted plants and uses a light to indicate feeding requirements.

Insert the Fertometer’s probe into the soil and press the button. A yellow light indicates that your plant requires feeding. A green light indicates that your plant has sufficient nutrients in the soil. Do not add fertiliser if the red light shows. In short: the Fertometer makes it possible for you to provide the ideal conditions for your plant.
The Fertometer is ideally suited to lovers of luscious and healthy potted plants with plenty of flowers.The correct level of fertiliser is essential and can be accurately established. No more 'guesswork'!

You can use it for all potted plants*, both indoor and outdoor plants. Common potted plants are geraniums, surfinias, fuchsias and numerous small plants such as marigold, petunias and verbenas. The Fertometer is also eminently suitable for use with indoor varieties such as the ficus, begonias, cyclamen and hibiscus, and even for exotic plants such as palm trees, bamboos and bananas.

* Plants that have been potted up and have developed adequate root systems (not seedlings or cuttings).
The Fertometer is not recommended for orchids and plants which thrive on poor soil such as heather.
