Potassium, in common fertilizers, began as a potash salt and cannot be made synthetically. Instead, it is mined from now-dry, ancient seabeds. Once obtained, these natural salts are utilized to provide nutrients to plants.

When plants go yellow, it’s often the first instinct to reach for a rich balanced fertilizer.

Digital testing kits – tests for current pH levels and available amounts of nitrogen, phosphorus, and potassium.Although this is a water-on liquid feed for tomatoes, it’s also excellent for all container-grown bedding plants, agapanthus, dahlias etc. Use once a week once the first truss begins to set. Plants need nitrogen, phosphorus, and potassium, and without them, are unlikely to remain healthy for too long. The amount each plant needs varies from one species to the next and so different fertilizer products contain varying proportions or NPK ratios. High potassium fertilizer is easy to recognize by the higher 3rd number, for example, 0-0-60.
