Our general indoor plant food can be used for a multitude of different plants - always check each plant's specific needs (as some like to be fed on their leaves and some prefer to be misted on the base and the stem). As we make our plant food using nutritious seaweed harvested from a nearby beach. It is best used as a feed for your plants, therefore you should use it in their growing season (for most plants this is between March and September). Our seaweed food is a wonderful feed because it is rich in trace nutrients and carbohydrates, helping your plants to grow strong and healthy. To use our indoor plant tonic, fill the clear glass bottle with water, then place two droplets of feed into the water - shake to disperse and then happily mist the base or leaves during the growing season once every 7-10 days. (Make fresh every two weeks). Each set contains 100ml of natural plant food, designed to last for around a year. 100% natural ingredients.
